Discovery and Observations of the Unusually Luminous Type-Defying II-P/II-L Supernova ASASSN-13co
T. W. -S. Holoien, J. L. Prieto, O. Pejcha +13
We present photometric and spectroscopic observations of ASASSN-13co, an unusually luminous Type II supernova and the first core-collapse supernova discovered by the All-Sky Automa…
Reverberation Mapping of the Seyfert 1 Galaxy NGC 7469
B. M. Peterson, C. J. Grier, Keith Horne +43
A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about…
ASASSN-14ae: A Tidal Disruption Event at 200 Mpc
Thomas W. -S. Holoien, J. L. Prieto, D. Bersier +12
ASASSN-14ae is a candidate tidal disruption event (TDE) found at the center of SDSS J110840.11+340552.2 (~Mpc) by the All-Sky Automated Survey for Supernovae (ASAS-SN).…
AGN Type-casting: Mrk 590 No Longer Fits the Role
K. D. Denney, G. De Rosa, K. Croxall +9
We present multi-wavelength observations that trace more than 40 years in the life of the active galactic nucleus (AGN) in Mrk 590, traditionally known as a classic Seyfert 1 galax…
Discovery and Observations of ASASSN-13db, an EX Lupi-Type Accretion Event on a Low-Mass T Tauri Star
Thomas W. -S. Holoien, Jose L. Prieto, Krzysztof Z. Stanek +19
We discuss ASASSN-13db, an EX Lupi-type ("EXor") accretion event on the young stellar object (YSO) SDSS J051011.01032826.2 (hereafter SDSSJ0510) discovered by the All-Sky Automa…
