The Astrophysics & Cosmology group of the Technion - Israel Institute of Technology - expects to offer several postdoctoral fellowships. The main selection criteria will be outstanding research accomplishments, creativity and potential for future achievements. The positions are for up to three years depending on progress. The starting date is flexible, but not later than December 2021. Fellows are expected to carry out both independent, original research, as well as collaborative work with the group members. The main research interests of our group are the origin and formation of cosmic structures, planet formation and stellar evolution, radiative processes and outflows in AGNs, X-ray spectroscopy and the development of future gamma-ray detectors. At least two positions will be offered in theoretical cosmology (w/ Desjacques and w/ Nusser), two in observational and experimental high-energy astrophysics and AGNs (w/ Behar and w/ Laor), and 1 - 2 positions in stellar binaries and supernoave explosions (w/ Perets). Inquiries and requests for any additional information about all the positions can be directed to the address email listed below. Applicants should include a CV (with a list of publications) and a research statement (not to exceed 3 pages), and arrange for three letters of recommendation to be sent to the same email address ([email protected]). Review of applications will start on January 4, 2021 and continue until all the positions are filled.
