The Light Curve of Wind-Reprocessed Tidal Disruption Events
Brenna Mockler, David Khatami, Daniel Kasen +2
The source of the optical/UV emission in tidal disruption events (TDEs) remains an enduring question in the field. Connecting the observed emission to the source is critical for bo…
The Landscape of Thermal Transients from Supernova Interacting with a Circumstellar Medium
David Khatami, Daniel Kasen
The interaction of supernova ejecta with a surrounding circumstellar medium (CSM) generates a strong shock which can convert the ejecta kinetic energy into observable radiation. Gi…
The Circumstellar Environments of Double-Peaked, Calcium-strong Supernovae 2021gno and 2021inl
Wynn Jacobson-Galán, Padma Venkatraman, Raffaella Margutti +42
We present panchromatic observations and modeling of calcium-strong supernovae (SNe) 2021gno in the star-forming host galaxy NGC 4165 (D = 30.5 Mpc) and 2021inl in the outskirts of…
The X-ray and Radio Loud Fast Blue Optical Transient AT2020mrf: Implications for an Emerging Class of Engine-Driven Massive Star Explosions
Yuhan Yao, Anna Y. Q. Ho, Pavel Medvedev +9
We present AT2020mrf (SRGe J154754.2443907), an extra-galactic () fast blue optical transient (FBOT) with a rise time of days and a peak luminosit…
The Nickel Mass Distribution of Stripped-Envelope Supernovae: Implications for Additional Power Sources
Niloufar Afsariardchi, Maria R. Drout, David Khatami +3
We perform a systematic study of the Ni mass () of 27 stripped envelope supernovae (SESNe) by modeling their light-curve tails, highlighting that use of ``Arnett…
SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
