Dr. Anna Pasquali was appointed Private Lecturer (Priv. Doz.) yesterday by the Habilitation Conference of the Department of Physics and Astronomy of Heidelberg University. (2020/01/30)

Carolin Kimmig, BA student at ITA under supervison of Prof. Dullemond has shown, that a magnetocentrifugal wind-loss of protoplanetary disks could be strong enough to significantly change the orbits of protoplanets. (2020/01/09) 

Apl. Prof. Dr. Stefan Wagner (LSW) appointed as new director of the H.E.S.S. Experiment and as Spokesperson of the H.E.S.S. collaboration. (2019/11/19)

A researchers team with Andreas Koch (ZAH/ARI) completed the largest survey to date of the ultrafaint outskirts of nearby galaxies. These appear to correlate with brightness and type of a galaxy undermining their common formation scenario. (2019/10/22)

Dr. Anna Pasquali has received the teaching prize of the Department of Physics and Astronomy. (2019/10/18)
