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" …

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 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 …

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 elements …

We present the discovery and the photometric and spectroscopic study of H-rich Type II
