Baryonic effects for weak lensing. Part II. Combination with X-ray data and extended cosmologies
Aurel Schneider, Alexandre Refregier, Sebastian Grandis +6
An accurate modelling of baryonic feedback effects is required to exploit the full potential of future weak-lensing surveys such as Euclid or LSST. In this second paper in a series…
Baryonic effects for weak lensing. Part I. Power spectrum and covariance matrix
Aurel Schneider, Nicola Stoira, Alexandre Refregier +4
Baryonic feedback effects lead to a suppression of the weak lensing angular power spectrum on small scales. The poorly constrained shape and amplitude of this suppression is an imp…
Modelling baryonic feedback for survey cosmology
Nora Elisa Chisari, Alexander J. Mead, Shahab Joudaki +10
Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between to elucidate the nature of dark matter and dark e…
Cosmological constraints with deep learning from KiDS-450 weak lensing maps
Janis Fluri, Tomasz Kacprzak, Aurelien Lucchi +4
Convolutional Neural Networks (CNN) have recently been demonstrated on synthetic data to improve upon the precision of cosmological inference. In particular they have the potential…
Effects of baryons on weak lensing peak statistics
Andreas J. Weiss, Aurel Schneider, Raphael Sgier +3
Upcoming weak-lensing surveys have the potential to become leading cosmological probes provided all systematic effects are under control. Recently, the ejection of gas due to feedb…
Constraining Dark Matter models with extremely distant galaxies
Marco Castellano, Nicola Menci, Andrea Grazian +4
The investigation of distant galaxy formation and evolution is a powerful tool to constrain dark matter scenarios, supporting and in some cases surpassing other astrophysical and e…
