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 …

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 …

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 …

Type Ia supernovae (SNe Ia) are runaway thermonuclear explosions in white dwarfs that
result in the disruption of the white dwarf star, and possibly its nearby stellar companion …

We present the discovery of a peculiar dwarf nova KSP-OT-201712a using high-cadence,
multicolor observations made with the Korea Microlensing Telescope Network. KSP-OT …

In this study, we explore the characteristics of 'low-mass'(log (M⋆/M⊙)≤ 8) and
'intermediate-mass'(8< log (M⋆/M⊙)≤ 10) host galaxies of Type Ia supernovae (SNe Ia) …

In this study, we analyzed the optical observations of a subluminous Type Ia supernova (SN
Ia) 2017fzw, which exhibited high photospheric velocity (HV) at B-band maximum light. The …

\object {SN 2021aefx} is a normal Type Ia Supernova (SN) with red excess emission over
the first $\sim $2 days. We present detailed analysis of this SN using our high-cadence …

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 …
