Measuring satellite galaxy subhalo masses in redMaPPer clusters with UNIONS weak lensing data
Roman Akhmetshyn, Jack Elvin-Poole, Michael J. Hudson +13
The paper measures the weak gravitational lensing signal of satellite galaxies in rich clusters using UNIONS data to estimate their subhalo masses and study tidal stripping effects…

Assessing the large-scale angular clustering of UNIONS Lyman Break Galaxies via cross-correlations
Constantin Payerne, Christophe Yèche, William d'Assignies Doumerg +7
The paper evaluates the use of UNIONS-selected Lyman-break galaxies as tracers of large‑scale structure at high redshift, finding that cross‑correlations with CMB lensing and quasa…
