The effects of varying depth in cosmic shear surveys
Sven Heydenreich, Peter Schneider, Hendrik Hildebrandt +7
We present a semi-analytic model for the shear two-point correlation function of a cosmic shear survey with non-uniform depth. Ground-based surveys are subject to depth variations…
KiDS+VIKING-450 and DES-Y1 combined: Mitigating baryon feedback uncertainty with COSEBIs
Marika Asgari, Tilman Tröster, Catherine Heymans +12
We present cosmological constraints from a joint cosmic shear analysis of the Kilo-Degree Survey (KV450) and the Dark Energy Survey (DES-Y1), conducted using Complete Orthogonal Se…
Cosmology from large-scale structure: Constraining CDM with BOSS
Tilman Tröster, Ariel. G. Sánchez, Marika Asgari +9
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cos…
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…
Painting with baryons: augmenting N-body simulations with gas using deep generative models
Tilman Tröster, Cameron Ferguson, Joachim Harnois-Déraps +1
Running hydrodynamical simulations to produce mock data of large-scale structure and baryonic probes, such as the thermal Sunyaev-Zeldovich (tSZ) effect, at cosmological scales is…
Probing hot gas around luminous red galaxies through the Sunyaev-Zel'dovich effect
Hideki Tanimura, Gary Hinshaw, Ian G. McCarthy +7
We construct the mean thermal Sunyaev-Zel'dovich (tSZ) Comptonization y profile around Luminous Red Galaxies (LRGs) in the redshift range 0.16 < z < 0.47 from the Sloan Digital Sky…
