Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are…

PRIMER: JWST/MIRI reveals the evolution of star-forming structures in galaxies at z<2.5
Yipeng Lyu, Benjamin Magnelli, David Elbaz +9
The stellar structures of star-forming galaxies (SFGs) undergo significant size growth during their mass assembly and must pass through a compaction phase as they evolve into quies…

In-Situ Spheroid Formation in Distant Submillimeter-Bright Galaxies
Qing-Hua Tan, Emanuele Daddi, Benjamin Magnelli +14
The majority of stars in today's Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies. Their formation is still an unsolved problem. Infrar…
