SN 2025fhm: A central-engine powered Ic-BL supernova associated with X-ray transient EP250304a
Cui-Ying Song, Nan Jiang, Xiaofeng Wang +32
We present X-ray, optical, and radio follow-up observations of EP250304a, an extragalactic fast X-ray transient (EFXT) discovered by the Einstein Probe. Its X-ray light curve exhib…
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…
Infant Type Ia Supernovae from the KMTNet I. Multi-Color Evolution and Populations
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +6
We conduct a systematic analysis of the early multi-band light curves and colors of 19 Type Ia Supernovae (SNe) from the Korea Microlensing Telescope Network SN Program, including…
Helium-deficient ER UMa-type dwarf nova below the period minimum with a hot secondary
Youngdae Lee, Dae-Sik Moon, Sang Chul Kim +2
We present the discovery of a peculiar dwarf nova KSP-OT-201712a using high-cadence, multi-color observations made with the Korea Microlensing Telescope Network. KSP-OT-201712a exh…
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…
Long-rising Type II supernovae from PTF and CCCP
F. Taddia, J. Sollerman, C. Fremling +17
Supernova (SN) 1987A was a peculiar H-rich event with a long-rising (LR) light curve (LC), stemming from a compact blue supergiant star (BSG). Only a few similar events have been p…
Pictoris' inner disk in polarized light and new orbital parameters for Pictoris b
Maxwell A. Millar-Blanchaer, James R. Graham, Laurent Pueyo +54
We present -band observations of Pic with the Gemini Planet Imager's (GPI's) polarimetry mode that reveal the debris disk between ~0.3" (~6 AU) and ~1.7" (~33 AU), while sim…
