Changing-Look AGNs or Short-Lived Radio Sources?

Frontiers in Astronomy and Space Sciences, 2017
The evolution of extragalactic radio sources has been a fundamental problem in the study of active galactic nuclei for many years. A standard evolutionary model has been created based on observations of a wide range of radio sources.

Extragalactic Radio Sources and the WMAP Cold Spot

, 2007
We detect a dip of 20-45% in the surface brightness and number counts of NVSS sources smoothed to a few degrees at the location of the WMAP cold spot. The dip has structure on scales of approximately 1-10 degrees.

Extragalactic radio source evolution under the dual-population unification scheme [PDF]

, 1998
We show that a dual-population unification scheme provides a successful paradigm with which to describe the evolution and beaming of all bright extragalactic radio sources. The paradigm consists of two intrinsic radio-source populations, based on the two

The extragalactic radio-source population at 95 GHz

, 2008
We have used the Australia Telescope Compact Array (ATCA) at 95GHz to carry out continuum observations of 130 extragalactic radio sources selected from the Australia Telescope 20GHz (AT20G) survey. Over 90% of these sources are detected at 95 GHz, and we

The CHILES Continuum and Polarization Survey. I. Survey Design and Noise Characterization

The Astronomical Journal
We introduce and describe the CHILES Continuum and Polarisation (CHILES Con Pol) Survey, a 1000 hr 1.4 GHz wideband full polarization radio continuum deepfield with the Very Large Array, commensurate with the CHILES H i deepfield.

Powerful Radio Sources in the Southern Sky. II. A Swift X-Ray Perspective

The Astrophysical Journal Supplement Series, 2023
We recently constructed the G4Jy-3CRE, a catalog of extragalactic radio sources based on the GLEAM 4-Jy (G4Jy) sample, with the aim of increasing the number of powerful radio galaxies and quasars with similar selection criteria to those of the revised ...

Flaring γ-Ray Emission from High Redshift Blazars

Galaxies, 2016
High redshift blazars are among the most powerful objects in the Universe. Although they represent a significant fraction of the extragalactic hard X-ray sky, they are not commonly detected in γ-rays. High redshift ( z > 2 ) objects represent

Average fractional polarization of extragalactic sources at Planck frequencies

, 2018
Recent detailed simulations have shown that an insufficiently accurate characterization of the contamination of unresolved polarized extragalactic sources can seriously bias measurements of the primordial cosmic microwave background (CMB) power spectrum ...
