Direct shear kSZ correlation: controlling baryons without modeling galaxies
Anoma Ganguly, Emmanuel Schaan, Elisabeth Krause +1
Baryonic feedback redistributes gas within and around dark matter haloes, suppressing the small-scale matter power spectrum at a level that is now the leading systematic for upcomi…
Towards the Two-Loop EFTofLSS in Galaxy Lensing Surveys
Evan Saraivanov, Henrique Rubira, Vivian Miranda +1
Extracting cosmological information from Stage IV weak lensing surveys requires non-linear modelling of the matter power spectrum that is accurate across a broad range of scales an…
Constraining baryonic feedback and cosmology from DES Y3 and Planck PR4 62pt data. I. CDM models
Jiachuan Xu, Tim Eifler, Elisabeth Krause +3
We combine weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing, and their cross-correlations (so-called 62pt) to constrain cosmology and baryonic fee…
Fisher Forecasts for Cosmological Yields from pt Analysis of the Roman Space Telescope High Latitude Imaging Survey
Kaili Cao, David H. Weinberg, Vivian Miranda +4
The High Latitude Imaging Survey (HLIS) of NASA's Nancy Grace Roman Space Telescope will provide powerful tests of cosmological models through sensitive measurements of cosmic shea…
The SPHEREx Satellite Mission
James J. Bock, Asad M. Aboobaker, Joseph Adamo +111
SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…
