Ultraviolet to Infrared Spectroscopy of the Type Ibn SN 2023tsz Suggests a Lower-mass Progenitor
Sergiy S. Vasylyev, Griffin Hosseinzadeh, Luc Dessart +42
Type Ibn supernovae are stripped-envelope explosions whose spectra indicate interaction with dense, helium-rich and hydrogen-poor circumstellar material (CSM), making them importan…
Las Cumbres Observatory Gravitational-Wave Follow-up in the Third and Fourth Observing Runs: Strengths and Weaknesses of a Rapid Response Galaxy Targeted Strategy
Ido Keinan, Iair Arcavi, D. Andrew Howell +34
We present a summary of gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telescopes during the third (O3) and fourth (O4) observing runs of the…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster
L. Izzo, C. Gall, N. Khetan +47
Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…
When IIb Ceases To Be: Bridging the Gap Between IIb and Short-plateau Supernovae
Joseph R. Farah, D. Andrew Howell, Daichi Hiramatsu +13
Hydrogen-rich supernovae (SNe) span a range of hydrogen envelope masses at core collapse, producing diverse light curves from extended plateaus in Type II SNe to double-peaked Type…
Infant Core-collapse Supernovae with Circumstellar Interactions from KMTNet I: Luminous Transitional Case of KSP-SN-2022c
Nan Jiang, Dae-Sik Moon, Yuan Qi Ni +6
We present multi-band high-cadence observations of a Type II supernova (SN) KSP-SN-2022c from a star-forming galaxy at 0.041 from its infant to nebular phase. Ea…
Origin of high-velocity ejecta and early red excess emission in the infant Type Ia supernova 2021aefx
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +5
SN~2021aefx is a normal Type Ia Supernova (SN) with red excess emission over the first 2 days. We present detailed analysis of this SN using our high-cadence KMTNet multi-ba…
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…
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…
