Properties of Polarized Radio Sources in the Wide Chandra Deep Field South from 2 to 4GHz

Samantha Adams, Mark Lacy, Preshanth Jagannathan +14

We present a study of the linear polarization properties of radio sources within the 10 deg Wide Chandra Deep Field South (W-CDFS) in S-band (2-4 GHz). Our W-CDFS image has an…

The X-ray Link Between High Eddington Ratio Dust-Obscured Galaxies (DOGs) and Hot DOGs

Fan Zou, W. N. Brandt, Elena Gallo +2

Dust-obscured galaxies (DOGs) with extremely red optical-to-infrared colors are often associated with intense starburst and AGN activity. Studying DOGs can provide insights into th…
