JVLA and VLBA Study of the Merging Cool Core CHIPS 1911+4455 at z ∼ 0.5 Radio Emission from an Infant Active Galactic Nucleus and from a Rapidly Star-forming Brightest Cluster Galaxy

The Astrophysical Journal
Recent studies of galaxy clusters found peculiar cases at the boundary between noncool core and cool core systems. While unusual, these objects can help us understand the evolution of the most massive clusters. We investigated the role of active galactic

Bright [C II]158 μm Streamers as a Beacon for Giant Galaxy Formation in SPT2349-56 at z = 4.3

The Astrophysical Journal
Observations of extreme starbursts, often located in the cores of protoclusters, challenge the classical bottom-up galaxy formation paradigm. Giant elliptical galaxies at z = 0 must have assembled rapidly, possibly within few 100 Myr through an extreme ...
