Scientist with experience in modelling of hot plasmas

Deadline: March 26, 2020

Job Announcement Text: SRON's mission is to bring about breakthroughs in international space research. Therefore the institute develops pioneering technology and advanced space instruments, and uses them to pursue fundamental astrophysical research, Earth science and exoplanetary research. As national expertise institute, SRON gives counsel to the Dutch government and coordinates national contributions to international space missions. SRON stimulates the implementation of space science in our society. The Astrophysics Program of SRON concentrates on the evolution of galaxies, star formation over cosmic time, and black holes. An important ingredient is connecting this science with the space instruments SRON builds and collaborating with the worldwide user community. Our Astrophysics Program has a vacancy in its laboratory in Utrecht for a tenure track position for a Scientist with experience in modelling of hot plasmas (f/m) Vacancy number 'SRON 1591'

Research: The study of hot plasmas in the X-ray band improved significantly since the launch of the satellites XMM-Newton and Chandra. Even more exciting times are ahead of us with XRISM (to be launched early 2022) and Athena (to be launched in 2031). Correct analysis of the data does not only depend on the instrument performance and its calibration but also on the correct modelling of these plasmas. This modelling is based on databases containing thousands to millions of transitions (e.g. SPEX, AtomDB) but the accuracy of these databases is often the limiting factor for the correct interpretation of high-resolution X-ray spectra. SRON has a long track record in this field (the SPEX code was developed at SRON) and plans to continue this into the next decade. Therefore, SRON seeks a scientist for a tenure track position who is able to lead our contributions in this field. In addition to this contribution to the modelling, the scientist will also participate in front line research in this field, preferably with an emphasis on extragalactic astrophysics but good candidates in other fields are also encouraged to apply.

Expertise: (1) demonstrated capability to produce model spectra of hot plasmas using detailed atomic data and to perform calculations of these atomic data; (2) demonstrated track record in the field of observational astrophysics using high-energy satellites and high-resolution X-ray spectral data, including successful observation proposals led as PI.

Employment conditions: This is a fulltime tenure track position with an initial employment period of four years. Together with the candidate we will set up a SMART assessment procedure with clear criteria and milestones. Upon successfully passing the evaluation after three years the candidate will be offered a permanent position. The start date of this position can be determined in mutual agreement. SRON is committed to an inclusive and flexible workplace. We encourage applications from qualified applicants of all sexual orientations and gender expressions, members of visible minorities, persons with disabilities, and potential dual-academic-career hires.

Information and application: More information about SRON can be found at www.sron.nl. For further information about the position, please contact prof. dr. Jan-Willem den Herder of the Astrophysics Program at +31-88 777 5894. If you wish to apply you can send a motivation letter, a concise research plan of 2-4 pages, your CV (about 2 pages) and the names and addresses of three references (incl. contact details) via email to jobs@sron.nl. Please state the vacancy number "SRON 1591" in the subject of your mail. Applications will be accepted until 1 March 2020.

PhD position in extragalactic astronomy

Deadline: Wednesday, April 1, 2020

Job Announcement Text: Applications are invited for one PhD position in extragalactic astrophysics at the Laboratoire d'Astrophysique de Marseille in France, to start Fall 2020 or earlier. Successful applicants will work with Alexandre Beelen and Veronique Buat on exploiting the rich dataset of the NOEMA Large Program z-GAL, whose primary goal is a comprehensive redshift survey of a sample of 200 of the brightest SubMillimeter Galaxies from the main Herschel surveys. The successful PhD candidate will be fully part of the z-GAL collaboration project, and will work in close collaboration with all its members. Within this project, the specific thesis objectives are (i) to study of the dust continuum properties of the z-GAL sources and their evolution with redshift, which is a crucial information for galaxy evolution models and (ii) to derive the properties of the interstellar medium, from which stars are formed, in high redshift starburst galaxies with mean stacked spectra of the z-GAL sample by identifying faint emission lines from the molecular and atomic gas. Both, dust continuum and emission lines, are key tracers of star formation activities and will help us understanding the physical conditions of star formation in these objects. The PhD student will also participate to the follow-up observations of the z-GAL program, in particular at radio wavelength, and the high-angular resolution follow-up of the most interesting sources. She/he will also contribute to the production of z-GAL sources catalogue including physical properties. Using already existing tools, she/he will perform source detection in data-cubes, and/or develop new optimal methods to robustly extract their spectra, later used to extract physical properties as dust masses and star formation rate/history.

Information and application: Interested candidates need submit a CV, cover letter, marks and ranking for the master and 2 letters of recommendation. Deadline for applications is April 1st, 2020. Attention To: Dr. Alexandre Beelen (alexandre.beelen@lam.fr)
