Identifying Changing-Look AGN Transitions in Light Curve Data with the Zwicky Transient Facility
Margaret E. Verrico, K. Decker French, Vivienne F. Baldassare +10
Changing-Look AGN (CL-AGN) are AGN which transition between Seyfert types, challenging AGN unification models. Most CL-AGN have been identified via repeat spectroscopy, making it d…
Mixing Paint: An analysis of color value transformations in multiple coordinate spaces using multivariate linear regression
Alexander Messick
I explore the mathematical transformation that occurs in color coordinate space when physically mixing paints of two different colors. I tested 120 pairs of 16 paint colors and use…
A Large-Scale Search for Photometrically Variable AGNs in Dwarf Galaxies Using the Young Supernova Experiment
Alexander Messick, Vivienne Baldassare, David O. Jones +12
We conduct an analysis of over 60,000 dwarf galaxies (7<=log(M_*/M_\odot)<=10) in search of photometric variability indicative of active galactic nuclei (AGNs). Using data from the…
X-ray Properties of Optically Variable Low-mass AGN Candidates
Alexander Messick, Vivienne Baldassare, Marla Geha +1
We present an X-ray analysis of fourteen nearby (z < 0.044) AGN in low mass galaxies (M_* <= 5*10^9 Msun) selected based on their optical variability (Baldassare et al. 2020). Comp…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
