Ongoing Star Formation In AGN Host Galaxy Disks: A View From Core-collapse Supernovae
, 2010 The normalized radial distribution of young stellar populations (and cold gas) in nearby galactic disks is compared between AGN host galaxies and starforming galaxies (both with Hubble types between S0/a and Scd) by using type II supernovae (SNe) as ...

Investigating the Star Formation Characteristics of Radio Active Galactic Nuclei
The Astrophysical JournalThe coevolution of supermassive black holes and their host galaxies represents a fundamental question in astrophysics. One approach to investigating this question involves comparing the star formation rates (SFRs) of active galactic nuclei (AGNs) with ...

PRIMUS: The relationship between Star formation and AGN accretion [PDF]
arXiv, 2014 We study the evidence for a connection between active galactic nuclei (AGN) fueling and star formation by investigating the relationship between the X-ray luminosities of AGN and the star formation rates (SFRs) of their host galaxies. We identify a sample of 309 AGN with $10^{41}
arxiv
The Astrophysical JournalWe investigate the properties of active galactic nuclei (AGNs) in the brightest submillimeter galaxies (SMGs) in the COSMOS field. We utilize the bright sample of the ALMA/SCUBA-2 COSMOS Survey (AS2COSMOS), which consists of 260 SMGs with S _870 _μ _m =

The Masses of AGN Host Galaxies and the Origin of Radio Loudness
, 2006 We highlight some of the principal results from our recent Hubble Space Telescope studies of quasars and radio galaxies. The hosts of these powerful AGN are normal massive ellipticals which lie on the region of the fundamental plane populated predominantly by massive ellipticals with boxy isophotes and distinct cores.

The host galaxies of radio-loud AGN: mass dependencies, gas cooling and AGN feedback
, 2005 The properties of the host galaxies of a well-defined sample of 2215 radio-loud AGN with redshifts 0.03 < z < 0.3, defined from the SDSS, are investigated. These are predominantly low radio luminosity sources, with 1.4GHz luminosities of 10^23 to 10^25 W/

The Intrinsic Sizes of Odd Radio Circles
The Astrophysical JournalA new class of sources, the so-called odd radio circles (ORCs), have been discovered by recent sensitive, large-area radio continuum surveys. The distances of these sources have so far relied on photometric redshifts of optical galaxies found at the ...

The Host Galaxies Of Agn With Powerful Relativistic Jets
, 2016 We present deep Near-infrared (NIR) images of a sample of 19 intermediate-redshift (0.3<z<1.0) radio-loud active galactic nuclei (AGN) with powerful relativistic jets (L1.4GHz >10^27 WHz^-1), previously classified as flat-spectrum radio quasars. We also compile host galaxy and nuclear magnitudes for blazars from literature.

Multiwavelength perspective of AGN evolution
, 2010 Discovering and studying obscured AGN at z>1-3 is important not only to complete the AGN census, but also because they can pinpoint galaxies where nuclear accretion and star-formation are coeval, and mark the onset of AGN feedback.
