Consistently Reproducing Early Galaxy Observations and 21-cm Signal during the Epoch of Reionization
Michele Bianco, Sambit K. Giri, Arghyadeep Basu\orcidlink +5
In the standard cosmological model, galaxies forming within dark matter haloes are the primary drivers of the Epoch of Reionization (EoR). The complex physics of galaxy formation i…
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 Kovač +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…
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…
Baryonification II: Constraining feedback with X-ray and kinematic Sunyaev-Zel'dovich observations
Michael Kovač, 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…
Baryonification: An alternative to hydrodynamical simulations for cosmological studies
Aurel Schneider, Michael Kovač, 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…
An analytical model for the dispersion measure of Fast Radio Burst host galaxies
Robert Reischke, Michael Kovač, Andrina Nicola +2
The dispersion measure (DM) of fast radio bursts (FRBs) is sensitive to the electron distribution in the Universe, making it a promising probe of cosmology and astrophysical proces…
Testing common approximations to predict the 21cm signal at the Epoch of Reionization and Cosmic Dawn
Timothée Schaeffer, Sambit K. Giri, Aurel Schneider
Predicting the 21cm signal from the epoch of reionization and cosmic dawn is a complex and challenging task. Various simplifying assumptions have been applied over the last decades…
The 21-cm signal during the end stages of reionization
Sambit K. Giri, Michele Bianco, Timothée Schaeffer +3
During the epoch of reionization (EoR), the 21-cm signal allows direct observation of the neutral hydrogen (HI) in the intergalactic medium (IGM). In the post-reionization era, thi…
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…
