AGN Feedback: The impact of galactic-scale radio jets on the interstellar medium in starbursting obscured AGN
M. Polletta, C. J. Lonsdale, P. Pallavi +3
A highly star-forming galaxy at z ~ 2 hosting an obscured, luminous active galactic nucleus (AGN) and a relativistic radio jet sets the stage for a cosmic crime scene. The victim i…
Fueling and feedback mechanisms at the nodes of the cosmic web
M. Polletta, G. De Lucia, A. R. Gallazzi +1
The environment plays a key role in shaping how galaxies form and evolve. Galaxies in dense nodes of the cosmic web are thought to grow and quench earlier, and faster and become mo…
Strong environmental AGN enhancement among DSFGs in z > 2 protoclusters
Monica Natalia Isla Llave, Fabio Vito, Alberto Traina +17
Galaxy protoclusters (PCs) at z > 2 are dense regions in which cold gas availability and elevated galaxy interaction rates trigger intense, often dust-obscured, star formation. The…
PEARLS: JWST Counterparts of Micro-Jy Radio Sources in the NEP Time Domain Field. II. All Four Spokes
S. P. Willner, Hansung B. Gim, Maria del Carmen Polletta +18
JWST/NIRCam observations in the North Ecliptic Pole Time Domain Field (TDF) identify 4.4 micron counterparts for 206 of 211 radio sources with S(3 GHz) \gapprox 5 micro-Jy in a 65a…
The Distribution of Quenched Galaxies in the Massive z = 0.87 Galaxy Cluster El Gordo
Rachel Honor, Seth Cohen, Timothy Carleton +27
El Gordo (ACT-CL J01024915) is a massive galaxy cluster with two major mass components at redshift . Using SED fitting results from JWST/NIRCam photometry, the fraction…
An ALMA spectroscopic survey of the Planck high-redshift object PLCK G073.4-57.5 confirms two protoclusters
Ryley Hill, Maria del Carmen Polletta, Matthieu Bethermin +3
Planck's High-Frequency Instrument observed the whole sky between 350um and 3mm, discovering thousands of unresolved peaks in the cosmic infrared background. The nature of these pe…
