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 cosmological …

We perform a systematic study of the 56 Ni mass (M Ni) of 27 stripped-envelope supernovae
(SESNe) by modeling their light-curve tails, highlighting that use of" Arnett's rule" …

SN 2018aoz is a Type Ia SN with a B-band plateau and excess emission in infant-phase
light curves≲ 1 day after the first light, evidencing an over-density of surface iron-peak …

Context. Type II supernovae (SNe II) mark the endpoint in the lives of hydrogen-rich massive
stars. Their large explosion energies and luminosities allow us to measure distances …

SN 2021aefx is a normal Type Ia supernova (SN) showing excess emission and redward
color evolution over the first∼ 2 days. We present analyses of this SN using our high …

We present the discovery of 48 new and the analysis of 55, including seven previously
discovered dwarf galaxy candidates (DGCs) around the giant spiral galaxy NGC 2997 using …

We present 56Ni mass estimates for 110 normal Type II supernovae (SNe II), computed here
from their luminosity in the radioactive tail. This sample consists of SNe from the literature …

Recent works have indicated that the 56 Ni masses estimated for stripped envelope
supernovae (SESNe) are systematically higher than those estimated for SNe II. Although this …

We report the early discovery and multicolor (BVI) high-cadence light-curve analyses of the
rapidly declining sub-Chandrasekhar Type Ia supernova KSP-OT-201509b (= AT 2015cx) …

We present a systematic study of Type II supernovae (SNe II) originating from progenitors
with effective temperatures (T eff) and luminosities closely resembling red supergiants …
