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…
High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
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…
The suppression of the matter power spectrum: strong feedback from X-ray gas mass fractions, kSZ effect profiles, and galaxy-galaxy lensing
Jared Siegel, Leah Bigwood, Alexandra Amon +6
Baryon feedback redistributes gas relative to the underlying dark matter distribution and suppresses the matter power spectrum on small scales, but the amplitude and scale dependen…
DARKSKIES: A suite of super-sampled zoom-in simulations of galaxy clusters with self-interacting dark matter
David Harvey, Yves Revaz, Matthieu Schaller +3
We present the "DARKSKIES" suite of one hundred, zoom-in hydrodynamic simulations of massive ( galaxy clusters with self-interacting dark matt…
