Constraining dark matter decays with cosmic microwave background and weak lensing shear observations
Jozef Bucko, Sambit K. Giri, Aurel Schneider
From observations at low and high redshifts, it is well known that the bulk of dark matter (DM) has to be stable or at least very long-lived. However, the possibility that a small…
Euclid: Modelling massive neutrinos in cosmology -- a code comparison
J. Adamek, R. E. Angulo, C. Arnold +133
The measurement of the absolute neutrino mass scale from cosmological large-scale clustering data is one of the key science goals of the Euclid mission. Such a measurement relies o…
Suppressing variance in 21-cm signal simulations during reionization
Sambit K. Giri, Aurel Schneider, Francisco Maion +1
Current best limits on the 21-cm signal during reionization are provided at large scales (100 Mpc). To model these scales, enormous simulation volumes are required which a…
CosmoGridV1: a simulated CDM theory prediction for map-level cosmological inference
Tomasz Kacprzak, Janis Fluri, Aurel Schneider +2
We present CosmoGridV1: a large set of lightcone simulations for map-level cosmological inference with probes of large scale structure. It is designed for cosmological parameter me…
Modeling HI at the field level
Andrej Obuljen, Marko Simonović, Aurel Schneider +1
We use an analytical forward model based on perturbation theory to predict the neutral hydrogen (HI) overdensity maps at low redshifts. We investigate its performance by comparing…
A Full CDM Analysis of KiDS-1000 Weak Lensing Maps using Deep Learning
Janis Fluri, Tomasz Kacprzak, Aurelien Lucchi +3
We present a full forward-modeled CDM analysis of the KiDS-1000 weak lensing maps using graph-convolutional neural networks (GCNN). Utilizing the , a novel m…
