Baryonification IV: Constraining baryonic feedback with X-ray gas fractions

Jozef Bucko, Andrina Nicola, Aurel Schneider +8

Baryonic feedback redistributes gas around dark matter halos, suppressing the matter power spectrum at scales now probed by weak lensing surveys. X-ray observations directly trace…

Analytical covariances for catalogue-based pseudo-s

Kevin Wolz, Elyas Farah, Robert Reischke +2

Multiple cosmological observables, such as the galaxy overdensity or cosmic shear, consist of fields sampled at the discrete positions of astrophysical sources. Recent work has pre…

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 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…

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…

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…

Cross-correlation between soft X-rays and galaxies A new benchmark for galaxy evolution models

Johan Comparat, Andrea Merloni, Gabriele Ponti +11

This article presents the construction and validation of complete stellar mass-selected, volume-limited galaxy samples using the Legacy Survey (data release 10) galaxy catalogs, co…

Constraining the primordial power spectrum using a differentiable likelihood

Subarna Chaki, Andrina Nicola, Alessio Spurio Mancini +2

The simplest inflationary models predict the primordial power spectrum (PPS) of curvature perturbations to be nearly scale-invariant. However, various other models of inflation pre…

A 1% accurate method to include baryonic effects in galaxy-galaxy lensing models

Matteo Zennaro, Giovanni Aricò, Carlos García-García +6

Galaxy clustering and galaxy-galaxy lensing are two of the main observational probes in Stage-IV large-scale structure surveys. Unfortunately, the complicated relationship between…

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…

Constraining the dispersion measure redshift relation with simulation-based inference

Koustav Konar, Robert Reischke, Steffen Hagstotz +2

We use the dispersion measure (DM) of localised Fast Radio Bursts (FRBs) to constrain cosmological and host galaxy parameters using simulation-based inference (SBI) for the first t…

LimberJack.jl: auto-differentiable methods for angular power spectra analyses

J. Ruiz-Zapatero, D. Alonso, C. García-García +5

We present LimberJack.jl, a fully auto-differentiable code for cosmological analyses of 2 point auto- and cross-correlation measurements from galaxy clustering, CMB lensing and wea…
