Euclid: Discovery of bright Lyman-break galaxies in UltraVISTA and Euclid COSMOS

R. G. Varadaraj, R. A. A. Bowler, M. J. Jarvis +163

We present a search for Lyman-break galaxies using the near-infrared UltraVISTA survey in the COSMOS field, reaching depths in of 26.2.…

Dust scattering halo of 4U 1630-47: High resolution X-ray and mm observations constrain source and molecular cloud distances

E. Kalemci, M. Díaz Trigo, E. Oztaban +8

We re-investigated the distance to the black hole X-ray binary 4U 1630-47 by analyzing its dust scattering halo (DSH) using high-resolution X-ray (Chandra) and millimeter (APEX) ob…

Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group

M. Urbano, P. -A. Duc, T. Saifollahi +160

Deep surveys reveal tidal debris and associated compact stellar systems. Euclid's unique combination of capabilities (spatial resolution, depth, and wide sky coverage) will make it…

GD-1 Stellar Stream and Cocoon in the DESI Early Data Release

Monica Valluri, Parker Fagrelius, Sergey. E. Koposov +49

We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence…
