HST Imaging of Fading AGN Candidates I: Host-Galaxy Properties and Origin of the Extended Gas
William C. Keel,W. Peter Maksym,Vardha N. Bennert,Chris Lintott,S. Drew Chojnowski,Alexei Moiseev,A. A. Smirnova,Kevin Schawinski,C. Megan Urry,Daniel A. Evans,Anna Pancoast,Bryan Scott,Charles Showley,Kelsi Flatland +13 more
TL;DR: In this paper, the authors presented a narrow-and medium-band HST imaging for 8 galaxies identified as hosting fading AGN on ~50,000-year timescales.
Journal ArticleDOI
Broad Hbeta Emission-Line Variability in a Sample of 102 Local Active Galaxies
Jordan N. Runco,Maren Cosens,Vardha N. Bennert,Bryan Scott,S. Komossa,Matthew A. Malkan,Mariana S. Lazarova,Matthew W. Auger,Tommaso Treu,Daeseong Park +9 more
TL;DR: In this paper, the authors studied profile changes of the broad Hbeta emission line within a 3-9 year time-frame between two sets of spectra and found that broad-line variability (in either width or flux) is observed in the majority (~66%) of the objects, resulting in a Seyfert-type change for ~38%.

TL;DR: Interferometric localization of the single-pulse FRB 180924 to a position 4 kiloparsecs from the center of a luminous galaxy at redshift 0.3214 indicates that some FRBs are clean probes of the baryonic component of the cosmic web.

TL;DR: In this paper, the authors modeled the ultraviolet spectra of the Seyfert 1 galaxy NGC 5548 obtained with the Hubble Space Telescope during the 6 month reverberation mapping campaign in 2014 and found that the time lags for the corrected emission lines are comparable to those for the original data.
