CRAL@Obs seminar by Hannah Ubler (MPE)
CRAL@Obs seminar by Hannah Ubler (MPE)
Observational constraints on massive black holes in the first billion years One of the most surprising results coming out of the first years of science operations with JWST is the unexpectedly high abundance of actively accreting black holes in the early Universe. Compared to the local population, many of these early black holes appear to […]

CRAL@ENS Seminar by Philipp Girichidis (Universität Heidelberg)
CRAL@ENS Seminar by Philipp Girichidis (Universität Heidelberg)
Cosmic rays in the interstellar medium Cosmic rays (CRs) are high energy particles with with an energy density comparable to the other energy densities in the interstellar medium (ISM) and very distinct cooling and transport processes. The low cooling efficiency of CRs allows them to travel long distances from their location of acceleration. As a […]
