Decaying Dark Matter Halo Abundance from a Revised Spherical Collapse Model
Thomas Montandon, Vivian Poulin, Oliver Hahn +2
We present a semi-analytical framework for the halo mass function (HMF) in decaying dark matter (DDM) cosmologies, in which dark matter decays into a massive daughter particle inhe…
Baryonification III: An accurate analytical model for the dispersion measure probability density function of fast radio bursts
MohammadReza Torkamani, Robert Reischke, Michael KovaÄ +6
We develop an analytical framework to predict the one-point probability distribution function (PDF) of dispersion measures (DMs) for fast radio bursts (FRBs) within the baryonifica…
Baryonification: An alternative to hydrodynamical simulations for cosmological studies
Aurel Schneider, Michael KovaÄ, Jozef Bucko +8
We present an improved baryonification (BFC) model that modifies dark-matter-only -body simulations to generate particle-level outputs for gas, dark matter, and stars. Unlike pr…
Baryonification II: Constraining feedback with X-ray and kinematic Sunyaev-Zel'dovich observations
Michael KovaÄ, Andrina Nicola, Jozef Bucko +6
Baryonic feedback alters the matter distribution on small and intermediate scales, posing a challenge for precision cosmology. The new, component-wise baryonification (BFC) approac…
Constraining Hot Dark Matter Sub-Species with Weak Lensing and the Cosmic Microwave Background Radiation
Fabian Hervas Peters, Aurel Schneider, Jozef Bucko +2
Although it is well known that the bulk of dark matter (DM) has to be cold, the existence of an additional sub-dominant, hot species remains a valid possibility. In this paper we i…
