ASASSN-18am/SN 2018gk : An overluminous Type IIb supernova from a massive progenitor
Subhash Bose, Subo Dong, C. S. Kochanek +29
ASASSN-18am/SN 2018gk is a newly discovered member of the rare group of luminous, hydrogen-rich supernovae (SNe) with a peak absolute magnitude of mag that is in…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
The ASAS-SN Bright Supernova Catalog -- IV. 2017
T. W. -S. Holoien, J. S. Brown, P. J. Vallely +41
In this catalog we compile information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) as well as all other bright (), spectr…
First Resolution of Microlensed Images
Subo Dong, A. Mérand, F. Delplancke-Ströbele +12
We employ VLTI GRAVITY to resolve, for the first time, the two images generated by a gravitational microlens. The measurements of the image separation θ_{-,+}=3.78 +/- 0.05 mas, an…
PS18kh: A New Tidal Disruption Event with a Non-Axisymmetric Accretion Disk
T. W. -S. Holoien, M. E. Huber, B. J. Shappee +38
We present the discovery of PS18kh, a tidal disruption event (TDE) discovered at the center of SDSS J075654.53+341543.6 ( Mpc) by the Pan-STARRS Survey for Transients.…
Seeing Double: ASASSN-18bt Exhibits a Two-Component Rise in the Early-Time K2 Light Curve
B. J. Shappee, T. W. -s. Holoien, M. R. Drout +109
On 2018 Feb. 4.41, the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered ASASSN-18bt in the K2 Campaign 16 field. With a redshift of z=0.01098 and a peak apparent magnit…
