The Late Time Optical Evolution of Twelve Core-Collapse Supernovae: Detection of Normal Stellar Winds
M. Rizzo Smith, C. S. Kochanek, J. M. M. Neustadt
We analyze the late time evolution of 12 supernovae (SNe) occurring over the last 41 years, including nine Type IIP/L, two IIb, and one Ib/c, using UBVR optical data from t…

Multiple Flares in the Changing-Look AGN NGC 5273
J. M. M. Neustadt, J. T. Hinkle, C. S. Kochanek +15
NGC 5273 is a known optical and X-ray variable AGN. We analyze new and archival IR, optical, UV, and X-ray data in order to characterize its long-term variability from 2000 to 2022…

Using AGN lightcurves to map accretion disc temperature fluctuations
J. M. M. Neustadt, C. S. Kochanek
We introduce a new model for understanding AGN continuum variability. We start from a Shakura--Sunyaev thin accretion disc with a steady-state radial temperature profile and…
