Model-Independent Measurement of Baryon Gas Fractions through Galaxy-Galaxy Lensing and the Kinematic Sunyaev-Zel'dovich Effect

R. Henry Liu, Uroš Seljak, Simone Ferraro +52

Baryon feedback is a leading source of systematic uncertainty for cosmology from weak lensing, but measurements of the gas distribution around galaxies have largely relied on param…

Optical Depths from the Thermal Sunyaev-Zel'dovich Effect with ACT DR6 and DESI DR1 Spectroscopic Galaxies and Optically-Selected Clusters

J. E. Moore, C. Popik, Y. Gong +66

We present stacked thermal Sunyaev-Zel'dovich (tSZ) effect measurements for three samples of galaxy groups and clusters: those traced by the Dark Energy Spectroscopic Instrument Da…

A Finely-Binned Measurement of the Connected Even-Parity Galaxy 4-Point Correlation Function of DESI Year 1 Luminous Red Galaxies

William Ortolá Leonard, Alex Krolewski, Zachary Slepian +46

We present the connected even-parity galaxy 4-Point Correlation Function (4PCF) of DESI Year 1 (Y1) Luminous Red Galaxies (LRGs). This is one of the first measurements of the conne…

A Unified Tracer Analysis of DESI DR2 Baryon Acoustic Oscillations

N. Sanders, H. Seo, M. Rashkovetskyi +65

We improve upon previous efforts to optimally combine overlapping galaxy samples in the DESI baryon acoustic oscillation analysis. By weighting each galaxy by its linear bias, over…

A new measurement of the FRB DM-galaxy cross correlation and a first joint analysis with the kinematic SZ effect

Samuel McCarty, Liam Connor, Kritti Sharma +8

Understanding the distribution of cosmic baryons is crucial for advancing cosmology and galaxy formation. Localized Fast Radio Bursts (FRBs) are a promising new probe of the diffus…

Validation of the DESI DR2 Ly forest full-shape analysis

M. Herbold, A. Cuceu, P. Martini +100

We present the validation of the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2) Lyman- (Ly) forest full-shape analysis. This analysis combines three-dimensi…
