Improved constraints on the Milky Way potential using the M68 stream and DESI spectroscopic data
Carles G. Palau, Wenting Wang, Jiaxin Han +41
We present a selection of stars belonging to the stellar stream of the M68 (NGC 4590) globular cluster, also known as Fjörm. This star selection is an improvement on previous ones…
Joint cosmological fits to DESI-DR1 full-shape clustering and weak gravitational lensing in configuration space
A. Semenaite, C. Blake, A. Porredon +69
We present a joint -pt cosmological analysis of auto- and cross-correlations between the Dark Energy Spectroscopic Instrument Data Release 1 (DESI-DR1) Bright Galaxy Surv…
DESI-DR1 -pt analysis: consistent cosmology across weak lensing surveys
A. Porredon, C. Blake, J. U. Lange +70
We present a joint cosmological analysis of projected galaxy clustering observations from the Dark Energy Spectroscopic Instrument Data Release 1 (DESI-DR1), and overlapping weak g…
An ultra-high-resolution map of (dark) matter
Diana Scognamiglio, Gavin Leroy, David Harvey +38
Ordinary matter-including particles such as protons and neutrons-accounts for only about one sixth of all matter in the Universe. The rest is dark matter, which does not emit or ab…
The DESI Transients Survey: Legacy Classifications and Methodology
Xander J. Hall, Antonella Palmese, Segev BenZvi +56
We present the first systematic spectroscopic observations of extragalactic transients from the Dark Energy Spectroscopic Instrument (DESI), as part of the DESI Transients Survey p…
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…
