Yun-Ting Cheng (Caltech): "Cosmology and Astrophysics from Intensity Mapping". You can find the schedule of upcoming café-clubs and the video of old ones here. Take care, Carlo, Mathilde, Meriam ---------------- ABSTRACT Intensity mapping has emerged as a promising tool to study the high redshift universe and the faint, diffuse extragalactic populations. Without resolving individual galaxies, […]

Georg HERZOG (Università di Milano "Bicocca"): "The present-day gas content of simulated field dwarf galaxies". You can find the schedule of upcoming café-clubs and the video of old ones here. Take care, Carlo, Meriam, Mathilde ---------------- ABSTRACT It is known from theory and observations that galaxy evolution can be influenced by environmental effects. Processes like ram pressure stripping in groups, clusters or the cosmic web as well as tidal stripping can affect the final properties of galaxies. However, until now no estimate exists on the relative importance of different processes for the final properties of field galaxies. Based on a high-resolution cosmological simulation I will show that there are two distinct processes that affect the present-day gas content of field dwarf galaxies. 1) Past interactions with massive hosts, in which a […]
