Now You See It, Now You Don't: The Disappearing Central Engine of the Quasar J1011+5442
Jessie C. Runnoe, Sabrina Cales, John J. Ruan +11
We report the discovery of a new "changing-look" quasar, SDSS J101152.98+544206.4, through repeat spectroscopy from the Time Domain Spectroscopic Survey. This is an addition to a s…
Towards an Understanding of Changing-Look Quasars: An Archival Spectroscopic Search in SDSS
John J. Ruan, Scott F. Anderson, Sabrina L. Cales +13
The uncertain origin of the recently-discovered `changing-looking' quasar phenomenon -- in which a luminous quasar dims significantly to a quiescent state in repeat spectroscopy ov…
P-MaNGA: Full spectral fitting and stellar population maps from prototype observations
David M. Wilkinson, Claudia Maraston, Daniel Thomas +31
MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is a 6-year SDSS-IV survey that will obtain resolved spectroscopy from 3600 to 10300 for a representative sample…
P-MaNGA: Gradients in Recent Star Formation Histories as Diagnostics for Galaxy Growth and Death
Cheng Li, Enci Wang, Lin Lin +31
We present an analysis of the data produced by the MaNGA prototype run (P-MaNGA), aiming to test how the radial gradients in recent star formation histories, as indicated by the 40…
Post-Starburst Quasars: Bridging the Gap Between Post-Starburst Galaxies and Quasars
Sabrina L. Cales, Michael S. Brotherton
In order to better understand the nature of post-starburst quasars (PSQs) in the context of galaxy evolution, we compare their properties to those of post-starburst galaxies and qu…
