General information

Reference : UMR9012-VALPIA-007
Workplace : ORSAY
Date of publication : Monday, May 03, 2021
Type of Contract : FTC Scientist
Contract Period : 24 months
Expected date of employment : 1 September 2021
Proportion of work : Full time
Remuneration : According to experience (minimum € 2,728 gross monthly)
Desired level of education : PhD
Experience required : Indifferent

Missions

The postdoc will be integrated into the Dark Energy Study Group (GREEN) of IJCLab (leader M. Moniez), which includes eight researchers experts in astronomy, astrophysics and cosmology. He will participate in the activities of the group related to the international project LSST (Legacy Survey of Space and Time), a survey of the southern hemisphere sky, carried out with an 8.40m diameter telescope equipped with a 3.2 billion pixels camera.
Atmospheric absorption corrections during LSST main telescope observations will rely on the measurement of spectrophotometric standard spectra with a dedicated auxiliary telescope (Auxtel). Our group has equipped this telescope with a holographic disperser, in order to reach a final photometric precision of a few millimagnitudes. This precision is a key element that will allow a better estimation of the photometric redshifts, also one of the fields of activity of the group.

Activities

The post-doc will participate in the start-up of the LSST survey at the Vera Rubin Observatory. This start-up includes a commissioning phase of less than a year, which will be followed by a year of observation before the first data release.
He/she will draw on our expertise in photometry and atmospheric models for the analysis and scientific exploitation of the auxiliary telescope data to develop correction procedures for the main telescope.
The postdoc will also be involved, depending on his/her background, in the scientific work of the GREEN host group of IJCLab, which deals with dark energy and dark matter issues.

Skills

The candidate should have a PhD in astronomy/astrophysics or fundamental physics with a cosmological component. He/she should have good computer skills, in particular in data analysis. Experience in observing with large telescopes will be appreciated.
The candidate should be fluent in written and spoken English and/or French, the two working languages of the host group.

Work Context

The position is located at the Irène Joliot-Curie Physics Laboratory of 2 infinities (IJCLab-CNRS, Orsay, France).
The Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a UMR under the supervision of the CNRS (IN2P3), the University of Paris-Saclay and the University of Paris is located on the campus of the University of Paris -Saclay in Orsay. The laboratory is located on the campus of the Université Paris-Sud, Université Paris-Saclay in Orsay. The campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
IJCLab was born in 2020 from the merger of five units (CSNSM, IMNC, IPN, LAL, LPT). The staff is made up of nearly 560 permanent (340 engineers, technicians and administrators and 220 researchers and teacher-researchers) and approximately 200 non-permanent including 120 doctoral students. The research themes of the laboratory are nuclear physics, high energy physics, theoretical physics, astroparticle physics, astrophysics and cosmology, particle accelerators, energy and the environment and health. IJCLab has very significant technical capacities (around 280 IT) in all the major fields required to design, develop / implement the experimental devices necessary for its scientific activity, as well as the design, development and use of instruments.

Constraints and risks

The selected candidate will be required to travel for technical and observational missions and to participate in meetings, workshops and conferences, both nationally and internationally.

Additional Information

To apply, please submit a detailed curriculum vitae, a publication list, a summary of previous research and a letter of motivation. In addition, please arrange for at least two letters of recommendation to be sent to the above addresses. Complete applications received by 15 May 2021 will receive full consideration; however, applications will continue to be received until the position is filled.
A committee will be formed to interview the candidates whose applications have been selected. The interviews will take place remotely.
As the position is located in a ZRR (restricted regime zone), the recruitment is conditional on obtaining a favorable opinion from the HFSD. Consequently, the starting date is given as an indication and may be postponed.
