The OpenGadget3 Code for Cosmological Simulations
Klaus Dolag, Geray S. Karademir, Luca Tornatore +28
We present the public release of OpenGadget3 (OG3), a substantially extended and re-organised version of the widely used Gadget-2/3 family of cosmological simulation codes. Since G…
Distinguishing cold and self-interacting dark matter through topological analysis
Adrian Szpilfidel, Clotilde Laigle, Pierre Boldrini +2
Alternative dark matter (DM) models have emerged to solve the challenges faced by the predictions of collisionless cold dark matter (CDM) on galactic scales ( Mpc). How…
Searching for signatures of self-interacting dark matter in halos from full physics simulations: From 3D structure to projected observables
Giovanni Y. Ferron, Antonio Ragagnin, Lorenzo Pizzuti +1
In this work we explore the imprints of self-interacting dark matter (SIDM) on the structure of simulated galaxy groups and clusters in view of future optical surveys. We find that…
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…
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…
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…
Testing the isothermal Jeans model for self-interacting dark matter halos in the collapse phase
Shubo Li, Moritz S. Fischer, Zixiang Jia +3
We benchmark the semi-analytical isothermal Jeans model against a high-resolution isolated N-body simulation that follows a self-interacting dark matter (SIDM) halo into deep core…
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…
