Joins Marrakech University in 1992 and founded with 5 other researchers the laboratory of high-energy physics and astrophysics in 1999. Works to create the first professional astronomical observatory in Morocco on Oukaimeden site, inaugurating it in 2007 and has been directing it since then.

Creates with a group of passionate people the Association of Astronomy amateurs of Marrakech (3AM), a cultural association aiming to promote astronomy and space science to the public.

His research works allow Morocco to be selected for the E-ELT project campaign. He conducted this project as part of the European FP6 program with the support of Hassan II academy for Science and Techniques in Morocco.

He is president of the National Committee for astronomy in Morocco (CNAM). Has just been elected president of the ArAS (Arab Astronomical Society), a professional association newly created (December 2016) and working towards the promotion of scientific research in Astrophysics in Arab countries. He is one of the founders of  “Africa Initiative for Planetary and Space Science '' and he is a member of its scientific advisory committee.

He is leading an ambitious project to create a 2 meters diameter telescope in Morocco. He is also leading the Atlas Dark Sky Morocco (ADSM) project. The project is aiming for the creation of a Dark Sky Reserve around the Oukaimeden observatory in Morocco. The reserve will cover a large area including the Toubkal National Park and the Oukaimeden observatory with a radius of about 80 km. It will become the largest Dark Sky Reserve worldwide and the first in North Africa.

Narrative Write-Up

Professor Benkhaldoun has been working for more than 30 years for the development of Astronomy and Astrophysics in Morocco. For this reason, he chose first the site-testing theme for observation in astronomy aiming to provide Morocco with an astronomical Observatory. His works on this area allowed him to showcase the good quality of Moroccan sites, mainly the ones of Oukaimeden mountains, and lastly of Aklim site, that was shortlisted as candidate for the future project of the largest telescope in the world; E-ELT.  

Within this thematic, Professor Benkhaldoun and his team first estimated the sky quality in terms of transparence and developed their own measuring instruments (Benkhaldoun, 1993, 1994). Within his laboratory, the candidate also put in place and used two astronomical seeing measurement instruments: the Differential Image Motion Monitor of Marrakech DIMMAR (Benkhaldoun et al, 2004 and 2005). This instrument uses images flickering caused by atmospheric turbulence to characterize the latter and deduct the seeing, which is a main site testing parameter.

The expertise he acquired in this field allowed Pr. Benkhaldoun to contribute with his team to the creation of an atmospheric profiler of a new type: the Single Star Scidar (SSS), by developing an inventive method of optimization calculus, based on what is called the simulated “recruit” « The Simulated Annealing Algorithm» (Habib et al, 2004, 2005).

Working on new concept using an interferometry method for the measure the phase fluctuation generated by the atmosphere turbulent motion, Mr. Benkhaldoun’s team developed a new instrument: Interferential Seenig Monitor ISM (Habib et al, 2008, 2013, on the long run, this instrument is supposed to replace the DIMM system taking into account its high efficiency and lower cost.

In addition to the instrumental development of these profilers, other techniques to extract turbulence profiles such as the usage of NCEP/NCAR meteorological data were put in place within the LPHEA team led by Mr Benkhaldoun (Y. Hach et al., MNRAS 2012). Therefore, on top of the instrumental development, professor Benkhaldoun showcased a strong theoretical knowledge, and therefore directed his team to contribute to the development of universal models of atmospheric seeing previsions (Benkhaldoun et al, 1994, 1996, 2003, Jabiri et al, 2001, Abahamid et al, 2004). These models are very useful for astronomers willing to schedule in advance the time and location of their observation.

Lastly, this characterization part of astronomical sites has been completed by the aerosols characterization, which is very annoying for observation in this region of the globe because of the proximity to Sahara. Dates of circulation of these aerosols were elaborated within the LPHEA. This part, studied in detailed, was the main subject of two thesis (Siher and Bounhir) supervised by Mr Benkhaldoun, as well as many scientific publications (Siher et al, 2002 et 2004, Bounhir et al, 2006, 2008 et 2009).

Many PHD students were therefore trained under the supervision of mister Benkhaldoun under the thematic of « site testing » (Jabiri, Siher, Abahamid, Habib, Bounhir and Hach), 5 of these researchers later joined his laboratory.

Year 2000 witnessed the organization in Marrakech of an important international conference on the thematic of site testing in visibility and radio (Site 2000). IAU (International Astronomical Union) and URSI (International Union of Radio Science) sponsored this conference and was a big success. Mr Benkhaldoun was the coordinator of the scientific comity and one of the three proceeding publishers. This proceedings are now a reference in the community (J. Vernin, Z. Benkhaldoun, and C. Muoz-Tunon, PASP 2002).

The scientific research conducted under this thematic contributed highly to the creation of Oukaimeden Observatory. This observatory was inaugurated in 1997 and Mr Benkhaldoun was naturally appointed director of this new research center belonging to Cadi Ayyad University.

In this context, and in thanks to the expertise acquired by professor Benkhaldoun on one hand, and the quality of Moroccan sites proves by scientific publications cited above on the other hand, the European community  (through ESO) chose one of the Moroccan sites as a possible candidate of the future 40m Diameter telescope called Extremely Large Telescope (E-ELT). This was a very complex challenge due to the site isolation, but it was successfully completed. Actually, Professor Benkhaldoun knew how to mobilize his team and the financial and logistic resources necessary to lead this project. This campaign allowed Morocco to get a consequent database on the astro-climatic parameters of the region. This subjected led to the completion of a PHD thesis (Sabil 2013) and to a number of publications (Bounhir et al 2008, Benhida et al 2010, Sabil et al 2010, Vernin et al 2011, Vasquez-Ramiro et al 2012, Varela et al 2014).

Since the creation of the project of Oukaimeden observatory, professor Benkhaldoun is working toward the target other scientific areas more linked to stellar observations and compatible with the instrumentation he owns or that he was able to acquire within international cooperation. These subjects are presented here after:

Magnitude limit in Optical Interferometry:

The context being the optical interferometers on the launch of the realization of the European Extremely Large Telescope. The very long baseline interferometry (VLBI) is at a strategic turning-point, which determines its scientific applications and its future by horizon of 2020. If it’s application scope can be extended to the low sources, then one of the main axes of development of the VLBI is the manufacturing of instruments, and even interferometers, that could complete the EELT by accessing the fine details that are beyond its resolution abilities. The goal is then to grasp the limits of the long baseline interferometers on the years 2020.

During one doctorate thesis defended in Mr Benkhaldoun laboratory in 2008 (T. Elhalkouj), the following have been developed:

      A new isopistonic angle calculation method, acceptable angle between two astronomical sources so as one can be used as a guidance source for the scientific target source (Elhalkouj et al 2008, Sabil et al 2010).

      A new cophasing method, called hierarchical (ThŹse Elhalkouj 2008).

      A global method of evaluation and optimization of the sky cover for an off axe cophasing( Elhalkouj 2006).

Mach Zehnder interferometer for coronography and apodisation.

The Oukaimeden observatory, under Mr Benkhaldoun supervision, is strongly involved in the R&D program on that topic. The coronography development is fundamental to reach the “final” objective of the EELT on detection and characterization of very faint sources (looking forward “bio-markers” on exo-earths).

The professor Benkhaldoun have conclude an agreement with several partners which allowed the acquisition and installation of materials needed to develop a testing bench at the Marrakech University for an experimental validation of those concepts of apodisation and coronography.

The LPHEA team has engaged in simulations and experimental tests of the apodisation happening by interferometry by using the Michelson interferometer (El Azahri et al, IAU 200, 2006) then the Mach-Zehnder interferometer (Carlotti et al, A&A 477, 2008). The LPHEA has then developed a homothetic technique for interferometric apodisation (Azagrouze, ThŹse 2012, Habib, A., et al, MNRAS 406, 2012).

Exoplanets:

As the detection and characterisation of exoplanets is booming among the international astronomic community, the OUCA has then naturally taken interest on it. Consequently, two techniques have been implemented at the Observatory. The “transit” technique, which consist in flow decrease detected when a planet is at the crossing point with its star (Daassou et al 2010, 2011). And the radial velocity technique consisting in doing a spectroscopy on the signal coming from the Exoplanet candidate to detect the offset due to the shift of the star gravity center because of the effect of the environing planet system. The Exoplanets atmosphere study is part of the professor Benkhaldoun team investigations. The first doctorate thesis in exoplanets (Ahmed Daassou) was defended in the Cadi Ayyad University in 2015.  

In February 2017, the Observatory team achieves a worldwide scientific accomplishment by participating to the discovery of a 7 telluric exoplanets system, from which at least 3 are in the Habitable zone of the star TRAPPIST-1 (named after the TRAPPIST program from which one of the telescopes – TRAPPIST-North is in Morocco at the Oukaimeden Observatory).

This discovery was published on the prestigious magazine Nature ( 23 February 2017), and the professor Benkhaldoun is one of the authors with one of his doctoral students (Khalidd Barkaoui).

Solar System Small bodies:

The instrumentation actually available in the Observatory, because of its modest size, allows only observation of objects relatively near to our environment. Hence, in addition to sky surveillance for contributing to the discovery of new near earth objects (NEO and NEA) along with comets (Benkhaldoun et al 2012), the Oukaimeden Observatory has started a collaboration with the teams of the planet studies of the Paris Observatory (IMCCE et IPG), from Toulouse university in France and from the Hassan II university of Casablanca regarding the meteors and meteorites (Chenaoui et al 2012). A school of astrophysics OISA 2009 held in the Oukaimeden, was dedicated to this topic and has resulted in an international cooperation program led on the Moroccan side by professor Benkhaldoun (Baratoux et al 2012).

The OUCA is since then equipped with multiple cameras and GPS systems for meteor trajectory detection on one side, and for impact flash detection (meteorites crash on the moon) on the other side (Daassou et al 2011, Bouley et al 2012). The first PhD thesis in this topic was defended on September 2016 at LPHEA (Mamon Ait Moulay El Arbi)

MOSS Program:

Professor Benkhaldoun has succeeded in convincing a French astronomer to install a telescope dedicated to the discovery of small bodies in the solar system. And by involving a Swiss astronomy association that has provided the dome, the MOSS, Moroccan Oukaimeden Sky Survey, project was born. This program is now a great success and the Oukaimeden, thanks to the MOSS telescope, is graded as the 7th best detector of asteroids and comets worldwide (2016). Four comets, five near earth asteroids and more than 6000 new objects have been detected by this telescope (moss-observatory.org ). With more than a million measurements sent to the Minor Planet Center (MPC) of the International Astronomic Union, the Oukaimeden Observatory has reached in 2017 the 27th rank on the all-time rating of more than 500 observatories listed by this institution.   

RENOIR Program:

The Oukaimeden Observatory has joined the ISWI (International Space Weather Initiative) through the RENOIR@OUCA project, the project being based on a scientific cooperation with a research team from the Illinois University. The aim is to install in the Oukaimeden Observatory, a series of optical and magnetic instruments for the detection of the effects inducted by the sun activity on the ionosphere and magnetosphere. The cooperation agreement was signed under impulse from professor Benkhaldoun in may 2013, and the first publications are now starting to be released (Benkhaldoun et al 2014, Fisher et al, 2015, Kaab et all 2017).

Education by a scientific research:

Professor Benkhaldoun is very engaged in this essential facet for developing a high-quality scientific research. Under his supervision, the first postgraduate course in Astronomy has started on 2000 at the Cadi Ayyad University. Since then, 7 Master classes have been held on that discipline. Many of those laureates have been able to do a thesis in its laboratory and five of them have joined the Oukaimeden Observatory as researchers. He has now eight PhD students under his mentorship.

Since the Oukaimeden Observatory inauguration, Mr. Benkhaldoun and his team decided to organize an international spring each two year. This school has been named OISA for Oukaimeden International School of Astrophysics and is now at its 7th edition (2016). The 2016 OISA edition was English speaking and directed toward Arab World students (FAWSA: First Arab Winter School for Astrophysics).

Outreach

It’s an aspect toward which professor Benkhaldoun is very keen and in which he is very involved. He has indeed created, with other passionate astronomers, an Astronomy association in Marrakech (3AM) that he has presided for more than 10 years. Each year this organization is holding an Astronomy festival (18th edition in 2017), along other events aimed toward the largest audience (schools and cultural centers animations). With his operations and his expertise, professor Benkhaldoun has helped in creation of a cultural center in Marrakech for which Astronomy is core activity (AGM cultural center).

Two Meter telescope project for Morocco

Professor Benkhaldoun is now working on the realization of a bigger project and that would lead to Morocco having a telescope of 2-meter diameter. With this in mind, an assembly of Moroccan astronomer is under creation and a national committee for Astronomy in Morocco has just been created. Professor Benkhaldoun is elected as president of this committee.
