********************************************************************************************************POSTDOCTORAL FELLOWSHIPS in GALAXY FORMATION and COSMOLOGY
********************************************************************************************************

We expect to offer postdoctoral fellowships to start in the fall of 2021 (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 (new recruit) 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 Nicolas Cornuault, Yakov 

Faerman, Jonathan Freundlich, Fangzhou Jiang, Karamveer Kaur and Kartick Sarkar. 

Recent postdocs still associated with the group include Daniel Ceverino, Colin DeGraf,  

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, 2020

 

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 Avishai Dekel at 

dekel@huji.ac.il and Nir Mandelker at nir.mandelker@mail.huji.ac.il
