Intracluster light and dark matter halo shapes reflect common assembly, not mutual coupling: shape correspondence in CDM but not SIDM
G. Martin, N. A. Hatch, W. Cui +8
The intracluster light (ICL) has been proposed as a luminous tracer of the dark matter (DM) halo shape in galaxy clusters, with recent observational studies and CDM simulations…
The dark fate of ultra-faint dwarfs: Gravothermal collapse in action
Moritz S. Fischer, Hai-Bo Yu
Ultra-faint dwarf (UFD) galaxies are a promising probe for dark matter (DM) physics as they are the most DM-dominated systems known. The Milky Way (MW) hosts many UFDs for which th…
Cooling, conduction, compact objects: Gravothermal evolution of dissipative self-interacting dark matter halos
Ludwig D. Schmidt, Moritz S. Fischer, Mathias Garny
Many proposed self-interacting dark matter (SIDM) models give rise to radiative processes that can dissipate energy. Understanding their impact on astrophysical objects through sim…
Accurately simulating core-collapse self-interacting dark matter halos
Moritz S. Fischer, Hai-Bo Yu, Klaus Dolag
The properties of satellite halos provide a promising probe for dark matter (DM) physics. Observations have motivated current efforts to explain surprisingly compact DM halos. If D…
Survival of the most compact: the life and death of satellite halos in self-interacting dark matter
David Klemmer, Moritz S. Fischer, Kimberly K. Boddy +2
Self-interacting dark matter (SIDM) models feature short-range interactions between dark matter (DM) particles that lead to larger diversity in the inner parts of galactic rotation…
The Cosmological Simulation Code OpenGadget3 - Implementation of Self-Interacting Dark Matter
Moritz S. Fischer, Marc Wiertel, Cenanda Arido +7
Dark matter (DM) could be subject to non-gravitational self-interactions which is relevant to resolve potential problems of cold DM on small scales. Their impact on astrophysical o…
