Extending SOMPZ beyond Spectroscopic Coverage for Roman Weak Lensing
Yufei Zhen, Chun-Hao To, Boyan Yin +7
Precision weak lensing cosmology requires accurate galaxy redshift distributions. However, the spectroscopic samples used to characterize these distributions do not fully span the…
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…
Measurement of the galaxy-velocity power spectrum of DESI tracers with the kinematic Sunyaev-Zeldovich effect using DESI DR2 and ACT DR6
Edmond Chaussidon, Selim C. Hotinli, Simone Ferraro +49
Joint analyses of high-resolution CMB temperature maps with galaxy surveys provide a unique way to reconstruct the radial velocity field of the underlying matter distribution via t…
Precision Kinematic Sunyaev--Zel'dovich Measurements Across Halo Mass and Redshift with DESI DR2 and ACT DR6: Part I. Luminous Red Galaxies
F. J. Qu, B. Ried Guachalla, E. Schaan +51
We present the most precise measurements of the kinetic Sunyaev-Zel'dovich (kSZ) effect around luminous red galaxies to date, detecting the signal at significance in both har…
The Power of DESI for Photometric Redshift Calibration: A Case Study with KiDS-1000
Diana Blanco, Alexie Leauthaud, Johannes Ulf Lange +64
Accurate redshift estimates are a critical requirement for weak lensing surveys and one of the main uncertainties in constraints on dark energy and large-scale cosmic structure. In…
A Unified Photometric Redshift Calibration for Weak Lensing Surveys using the Dark Energy Spectroscopic Instrument
Johannes U. Lange, Diana Blanco, Alexie Leauthaud +61
The effective redshift distribution of galaxies is a critical component in the study of weak gravitational lensing. Here, we introduce a new method for determining fo…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
Quantifying the Impact of LSST -band Survey Strategy on Photometric Redshift Estimation and the Detection of Lyman-break Galaxies
John Franklin Crenshaw, Boris Leistedt, Melissa Lynn Graham +8
The Vera C. Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST), promising to discover billions of galaxies out to redshift 7, using six photometric bands ($u…
Studying baryon acoustic oscillations using photometric redshifts from the DESI Legacy Imaging survey DR9
Christoph Saulder, Yong-Seon Song, Minji Oh +41
Context.The Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey DR9 (DR9 hereafter), with its extensive dataset of galaxy locations and photometric redshifts, present…
Measurements of the Thermal Sunyaev-Zel'dovich Effect with ACT and DESI Luminous Red Galaxies
R. Henry Liu, Simone Ferraro, Emmanuel Schaan +54
Cosmic Microwave Background (CMB) photons scatter off the free-electron gas in galaxies and clusters, allowing us to use the CMB as a backlight to probe the gas in and around low-r…
