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…

Forecasting local Primordial Non-Gaussianities from UNIONS Lyman-Break Galaxies and Planck CMB lensing

Constantin Payerne, William d'Assignies, Christophe Yèche +4

Local Primordial non-Gaussianities (PNGs), characterized by , provide a powerful window into the physics of inflation. Cross-correlating high-redshift tracer…

Cluster properties as a function of dynamical state in the DESI Legacy x UNIONS surveys

Syeda Lammim Ahad, Rashaad Reid, Charlie T. Mpetha +10

We investigate how the dynamical state of galaxy clusters influences their galaxy populations and mass distributions. Using photometrically selected clusters from the DESI Legacy I…

UNIONS Optical Identifications for VLASS Radio Sources in the Euclid Sky (UNVEIL) I. A Catalog of ~146,000 Radio Galaxies up to z~5

Yuxing Zhong, Kohei Ichikawa, Hendrik Hildebrandt +11

We present results of optical identifications for Very Large Array Sky Survey (VLASS) radio sources using the Ultraviolet Near Infrared Optical Northern Survey (UNIONS). A cross-ma…

Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS

Taketo Yoshida, Tohru Nagao, Yoshiki Toba +11

We report on the spectral energy distributions (SEDs) of infrared-bright dust-obscured galaxies (DOGs) with . Using photometry from the deep and wide…
