The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Infant-phase reddening by surface Fe-peak elements in a normal Type Ia Supernova
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +41
Type Ia Supernovae are thermonuclear explosions of white dwarf stars. They play a central role in the chemical evolution of the Universe and are an important measure of cosmologica…
Rapidly-Declining Hostless Type Ia Supernova KSP-OT-201509b from the KMTNet Supernova Program: Transitional Nature and Constraint on Ni Distribution and Progenitor Type
Dae-Sik Moon, Yuan Qi Ni, Maria R. Drout +8
We report the early discovery and multi-color () high-cadence light curve analyses of a rapidly-declining sub-Chandrasekhar Type Ia supernova KSP-OT-201509b (= AT2015cx) from…
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…
A Deep CFHT Optical Search for a Counterpart to the Possible Neutron Star -- Black Hole Merger GW190814
Nicholas Vieira, John J. Ruan, Daryl Haggard +10
We present a wide-field optical imaging search for electromagnetic counterparts to the likely neutron star - black hole (NS-BH) merger GW190814/S190814bv. This compact binary merge…
KSP-SN-2016kf: a long-rising H-rich Type II Supernova with unusually high Ni mass discovered in the KMTNet Supernova Program
Niloufar Afsariardchi, Dae-Sik Moon, Maria R. Drout +12
We present the discovery and the photometric and spectroscopic study of H-rich Type II supernova (SN) KSP-SN-2016kf (SN2017it) observed in the KMTNet Supernova Program in the outsk…
Aspherical Supernovae: Effects on Early Light Curves
Niloufar Afsariardchi, Christopher D. Matzner
Early light from core-collapse supernovae, now detectable in high-cadence surveys, holds clues to a star and its environment just before it explodes. However, effects that alter th…
