SN 2022jox: An Extraordinarily Ordinary Type II SN with Flash Spectroscopy

The Astrophysical Journal
We present high-cadence optical and ultraviolet (UV) observations of the Type II supernova (SN), SN 2022jox which exhibits early spectroscopic high-ionization flash features of H i , He ii , C iv , and N iv that disappear within the first few days after ...

Unravelling the Asphericities in the Explosion and Multifaceted Circumstellar Matter of SN 2023ixf

The Astrophysical Journal
We present a detailed investigation of photometric, spectroscopic, and polarimetric observations of the Type II SN 2023ixf. Earlier studies have provided compelling evidence for a delayed shock breakout from a confined dense circumstellar matter (CSM ...

NEOWISE-R Caught the Luminous SN 2023ixf in Messier 101

The Astrophysical Journal
During routine survey imaging, the reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3.6 through day 10.9, and again on the ...

Physical Properties of Type II Supernovae Inferred from ZTF and ATLAS Photometric Data

The Astrophysical Journal
We report an analysis of a sample of 186 spectroscopically confirmed Type II supernova (SN) light curves (LCs) obtained from a combination of Zwicky Transient Facility (ZTF) and Asteroid Terrestrial-impact Last Alert System observations.

Gravitationally Induced Neutrino-Oscillation Phases

, 2004
In this essay, we introduce a new effect of gravitationally induced quantum mechanical phases in neutrino oscillations. These phases arise from an hitherto unexplored interplay of gravitation and the principle of the linear superposition of quantum ...
