A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies

Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35

We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…

Dark Energy Survey Year 6 Results: Redshift Calibration of the MagLim++ Lens Sample

G. Giannini, A. Alarcon, W. d'Assignies +85

In this work, we derive and calibrate the redshift distribution of the MagLim++ lens galaxy sample used in the Dark Energy Survey Year 6 (DES Y6) 3x2pt cosmology analysis. The 3x2p…

DECADE+DES Y3 Weak Lensing Mass Map: A 13,000 deg View of Cosmic Structure from 270 Million Galaxies

M. Gatti, D. Anbajagane, C. Chang +37

We present the largest galaxy weak lensing mass map of the late-time Universe, reconstructed from 270 million galaxies in the DECADE and DES Year 3 datasets, covering 13,000 square…

Biasing from galaxy trough and peak profiles with the DES Y3 redMaGiC galaxies and the weak lensing mass map

Q. Hang, N. Jeffrey, L. Whiteway +83

We measure the correspondence between the distribution of galaxies and matter around troughs and peaks in the projected galaxy density, by comparing \texttt{redMaGiC} galaxies ($0.…

DELVE Milky Way Satellite Galaxy Census I: Satellite Population and Survey Selection Function in DES, DELVE, and Pan-STARRS

C. Y. Tan, A. Drlica-Wagner, A. B. Pace +84

The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. However, the population o…

Dark Energy Survey Year 6 Results: improved mitigation of spatially varying observational systematics with masking for the MagLim++ lens sample

M. Rodríguez-Monroy, N. Weaverdyck, J. Elvin-Poole +63

As photometric surveys reach unprecedented statistical precision, systematic uncertainties increasingly dominate large-scale structure probes relying on galaxy number density. Defi…
