An adapted filter function for density split statistics in weak lensing
Pierre Burger, Peter Schneider, Vasiliy Demchenko +4
Context. The density split statistics in weak gravitational lensing analyses probes the correlation between regions of different (foreground) galaxy number densities and their weak…
Cosmic voids: a novel probe to shed light on our Universe
Alice Pisani, Elena Massara, David N. Spergel +26
Cosmic voids, the less dense patches of the Universe, are promising laboratories to extract cosmological information. Thanks to their unique low density character, voids are extrem…
Cosmological Simulations for Combined-Probe Analyses: Covariance and Neighbour-Exclusion Bias
J. Harnois-Deraps, A. Amon, A. Choi +12
We present a public suite of weak lensing mock data, extending the Scinet Light Cone Simulations (SLICS) to simulate cross-correlation analyses with different cosmological probes.…
Studying galaxy troughs and ridges using Weak Gravitational Lensing with the Kilo-Degree Survey
Margot M. Brouwer, Vasiliy Demchenko, Joachim Harnois-Déraps +15
We study projected underdensities in the cosmic galaxy density field known as 'troughs', and their overdense counterparts, which we call 'ridges'. We identify these regions using a…
Testing the spherical evolution of cosmic voids
Vasiliy Demchenko, Yan-Chuan Cai, Catherine Heymans +1
We study the spherical evolution model for voids in CDM, where the evolution of voids is governed by dark energy at an earlier time than that for the whole universe or in overde…
The Birth of a Galaxy - III. Propelling reionisation with the faintest galaxies
John H. Wise, Vasiliy G. Demchenko, Martin T. Halicek +4
Starlight from galaxies plays a pivotal role throughout the process of cosmic reionisation. We present the statistics of dwarf galaxy properties at z > 7 in haloes with masses up t…
