********************************************************************************************************POSTDOCTORAL FELLOWSHIPS in GALAXY FORMATION and COSMOLOGY
********************************************************************************************************
We expect to offer postdoctoral fellowships to start in the fall of 2022 (or earlier),
potentially for three years. The cosmology group is looking especially for researchers
working on the theory of the formation, evolution and dynamics of galaxies and large-scale
structure, the circumgalactic and intergalactic medium, and the dynamics of multiphase
gas, including hydro-gravitational simulations, semi-analytic modeling and analytic work, in
close contact with observations (e.g. by machine learning).
The cosmology group, led by Avishai Dekel and Nir Mandelker, involves
Yuval Birnboim, Orly Gnat and Yehuda Hoffman. It is part of the Center for Astrophysics
and Planetary Science within the Racah Institute of Physics at the Hebrew University,
whose faculty members also include, Asaf Horesh, Tsvi Piran, Re'em Sari, Nir Shaviv
and Nick Stone.
Current postdocs working on galaxy formation at HU are Han Aung Zhaozhou Li, Karamveer Kaur and Kartick Sarkar.
Recent postdocs still associated with the group include Daniel Ceverino, Nicolas Cornuault, Colin DeGraf, Yakov Faerman, Jonathan Freundlich, Fangzhou Jiang, Sandro Tacchella, and Santi Roca-Fabrega.
Overall we have 12 astrophysics postdocs this year, working mainly in cosmology
and galaxies, high-energy astrophysics, and planetary systems. There are currently
18 astrophysics graduate students at our Center.
We pursue extensive collaborations with other leading groups in Israel, in Europe,
and in the US, and can consider joint arrangements.
Basic funding is available from research grants. Selected applicants may be asked
to also apply to specific competitive prize fellowships to be hosted at HU.
Interested candidates are invited to send their application material by email to Mrs.
Yulia Epstein yuliae@savion.huji.ac.il by December 20, 2021.
The material should include a curriculum vita, a list of publications, a brief summary
of past, current and planned research, and three letters of recommendation to be
sent directly by the referees.
Applicants are also asked to make an e-mail contact with Nir Mandelker at nir.mandelker@mail.huji.ac.il and Avishai Dekel at
