Analytical covariances for catalogue-based pseudo-s
Kevin Wolz, Elyas Farah, Robert Reischke +2
The paper presents a method to analytically compute the Gaussian (disconnected) covariance of angular power spectra estimated directly from discrete source catalogues, accounting f…
Statistical Field Theory for Weak Gravitational Lensing
Zheng Zhang, Philip Bull, Chris Clarkson +1
Standard weak-lensing calculations treat lensing as a linear remapping of the matter field along the line of sight. We instead formulate lensing as a stochastic field theory for th…
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…
Cross-correlation of Luminous Red Galaxies with ML-selected AGN in HSC-SSP III: HOD Parameters for Type I and Type II Quasars
Rodrigo Córdova Rosado, Andy D. Goulding, Jenny E. Greene +4
Understanding the dark matter (DM) halo environment in which galaxies that host active galactic nuclei (AGN) reside is a window into the nature of supermassive black hole (SMBH) ac…
An analytical model for the dispersion measure of Fast Radio Burst host galaxies
Robert Reischke, Michael KovaÄ, 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…
