Evolution of the Dual AGN in Mrk 266: A Young AGN and a Rotation Dominated Disk in the SW Nucleus
Mason Ruby, Francisco Müller-Sánchez, Julia M. Comerford +6
Dual active galactic nuclei (AGN) offer a unique opportunity to probe the relationship between super massive black holes (SMBH) and their host galaxies as well as the role of major…
Shocked POststarburst Galaxy Survey. III. The Ultraviolet Properties of SPOGs
Felipe Ardila, Katherine Alatalo, Lauranne Lanz +11
The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify galaxies in the transitional phase between actively star-forming and quiescence with nebular lines that are excited…
Shocked POststarburst Galaxy Survey II: The Molecular Gas Content and Properties of a Subset of SPOGs
Katherine Alatalo, Ute Lisenfeld, Lauranne Lanz +8
We present CO(1-0) observations of objects within the Shocked POststarburst Galaxy Survey taken with the Institut de Radioastronomie Millimetrique (IRAM) 30m single dish and the Co…
Shocked POststarbust Galaxy Survey I: Candidate Poststarbust Galaxies with Emission Line Ratios Consistent with Shocks
Katherine Alatalo, Sabrina L. Cales, Jeffrey A. Rich +6
[Abridged] The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify transforming galaxies, in which the nebular lines are excited via shocks instead of through star formati…
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…
Suppression of Star Formation in NGC 1266
K. Alatalo, M. Lacy, L. Lanz +11
NGC1266 is a nearby lenticular galaxy that harbors a massive outflow of molecular gas powered by the mechanical energy of an active galactic nucleus (AGN). It has been speculated t…
Catching Quenching Galaxies: The Nature of the WISE Infrared Transition Zone
Katherine Alatalo, Sabrina L. Cales, Philip N. Appleton +5
We present the discovery of a prominent bifurcation between early-type galaxies and late-type galaxies, in [4.6]-[12] micron colors from the Wide Field Infrared Survey Explorer (WI…
Future mmVLBI Research with ALMA: A European vision
R. P. J. Tilanus, T. P. Krichbaum, J. A. Zensus +165
Very long baseline interferometry at millimetre/submillimetre wavelengths (mmVLBI) offers the highest achievable spatial resolution at any wavelength in astronomy. The anticipated…
NGC1266 as a Local Candidate for Rapid Cessation of Star Formation
