Lensing in the Blue IV: The First Weak Gravitational Lensing Maps from the Stratosphere
Sayan Saha, Maya Amit, Jacqueline E. McCleary +42
The Super-Pressure Balloon-borne Imaging Telescope (SuperBIT) completed its science flight in April 2023, obtaining imaging data for 30 galaxy clusters. In this work, we present th…
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…
Fisher Forecasts for Cosmological Yields from pt Analysis of the Roman Space Telescope High Latitude Imaging Survey
Kaili Cao, David H. Weinberg, Vivian Miranda +5
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…
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…
Growth and Geometry Split in Light of the DES-Y3 Survey
Kunhao Zhong, Evan Saraivanov, Vivian Miranda +3
We test the smooth dark energy paradigm using Dark Energy Survey (DES) Year 1 and Year 3 weak lensing and galaxy clustering data. Within the CDM and CDM model we separate the…
Weak lensing by galaxy troughs in DES Science Verification data
D. Gruen, O. Friedrich, A. Amara +89
We measure the weak lensing shear around galaxy troughs, i.e. the radial alignment of background galaxies relative to underdensities in projections of the foreground galaxy field o…
