Near-infrared Variability Detected in the Young Star-Forming Dwarf Galaxy SBS 0335-052E
Shun Hatano, Mitsuru Kokubo, Masami Ouchi +17
SBS~0335-052E is a young star-forming dwarf galaxy with a total stellar mass of and an extremely low metallicity (), which…
Gas outflows in two recently quenched galaxies at z = 4 and 7
F. Valentino, K. E. Heintz, G. Brammer +33
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…
Enhanced gas-phase metallicities and suppressed outflows for galaxies in a rich cluster core at cosmic noon
Kota Adachi, Tadayuki Kodama, Jose Manuel Pérez-MartÃnez +2
We present the result of near-infrared spectroscopy using Keck/MOSFIRE for 23 member galaxies in an X-ray cluster XCS2215 () to investigate the environmental dependence of…
A merging pair of massive quiescent galaxies at in the Cosmic Vine
K. Ito, F. Valentino, M. Farcy +26
We report the spectroscopic confirmation of a merging pair of massive quiescent galaxies at . Using JWST observations, we confirm that the two galaxies lie at a projected s…
Large-Scale Stellar Age-Velocity Spiral Pattern in NGC 4030
Iris Breda, Glenn van de Ven, Sabine Thater +11
The processes driving the formation and evolution of late-type galaxies (LTGs) continue to be a debated subject in extragalactic astronomy. Investigating stellar kinematics, especi…
