Job Description
Postdoctoral position in microwave polarization analysis with the Fred Young Submillimeter Telescope (FYST) of the CCAT Observatory
We are seeking to fill one postdoctoral position within the ERC Advanced Grant project NewPhysCMB (Finding New Physics from the Polarized Light of the Cosmic Microwave Background), which aims to establish cosmological parity violation — in particular cosmic birefringence — as a new probe of the physics behind dark matter, dark energy, and cosmic inflation. The project combines improved measurements of CMB polarization parity-odd correlations (TB, EB) from existing and upcoming experiments with theoretical and numerical studies of their origin.
The position is funded by the ERC Advanced Grant 2025 program NewPhysCMB and the successful candidate will work closely with Prof. Dr. Eiichiro Komatsu, Director of the Department of Physical Cosmology at the Max Planck Institute for Astrophysics (MPA). Because MPA is part of the German consortium of the CCAT collaboration, the appointed candidate will have access to proprietary FYST data. See https://www.ccatobservatory.org for information on FYST.
The intended research projects include, but are not limited to, the analysis and interpretation of microwave polarization data with a focus on FYST science within Work Package 1 (WP1) of NewPhysCMB. Some of the addressed science topics include:
- Higher-level analysis of TB and EB correlations from FYST / Prime-Cam polarization observations at high frequencies (280–850 GHz), in close collaboration with the PI on low-level data analysis
- Characterization of polarized Galactic dust emission
- Related analyses of time-varying and anisotropic polarization-angle signals using FYST data
Within these areas, we seek to fill one postdoctoral position intended for a promising young scientist who completed their PhD within the last six years. The term of employment is four years. The nominal starting date is 1 September 2027, but earlier start dates are also possible depending on the availability of the selected candidate. The appointed candidate is expected to interact closely with other members of the Physical Cosmology department and with the CCAT collaboration.
Applicants are expected to have a strong background in CMB or submillimeter polarization data analysis, statistical inference, and/or Galactic foreground modeling. Experience with microwave mapmaking, power-spectrum estimation, or multi-frequency component separation is an advantage.
Salaries are paid at German civil service rates (the gross annual pre-tax income includes a special annual payment and depends on prior post-doctoral experience). The position comes with 30 days holiday entitlement, social security insurance (e.g. health insurance), and social benefits according to the regulations for public service.
The MPA (https://www.mpa-garching.mpg.de/) is a major German institution dedicated to theoretical, computational, and interpretational research in astrophysics and cosmology. We are situated north of Munich on a research campus which hosts the largest European concentration of astronomers. The campus is directly connected to central Munich by subway. The Institute offers a vibrant research community, runs a vigorous visitor programme and is housed in an attractive, specially designed building with excellent infrastructure, including powerful MPA-owned parallel computing clusters. It has also privileged access to supercomputers at the Max Planck Computing and Data Facility.
Interested scientists are invited to apply electronically via
https://wwwmpa.mpa-garching.mpg.de/appl/cmb2026/register.php
Candidates should upload (1) a full curriculum vitae (including the names and contact details of three references), (2) a publication list, and (3) a summary of their past research achievements and a statement on how they anticipate their expertise to mesh with the goals of NewPhysCMB / WP1, by 8 December 2026. Reference letters are not required at the application stage. Please provide the names and contact details of three referees in your CV. Referees of shortlisted candidates will be asked for a letter during the second stage of review (tentative deadline mid-January), so please let them know to expect our request.
