SN 2025dys: A luminous supernova explosion from a partially stripped helium star

We present well-sampled multi-band imaging and low- to medium-resolution spectroscopic observations of the early-discovered Type~II supernova (SN)~2025dys. The photometric evolution exhibits a rise time of $\sim$\,18 days ($r$ band) and a rapid decline transitioning to the radioactive decay tail at $\sim$\,70 days. SN~...

SN 2025qe: A case study of diversity in low-luminosity thermonuclear explosions

We present optical photometric and spectroscopic observations of SN 2025qe, a Type Iax supernova in IC 0529, monitored from $-10$ to $+150$ rest-frame days relative to $g'$-band maximum using the GROWTH-India and the Himalayan Chandra Telescopes. SN 2025qe reaches a peak $g'$-band absolute magnitude of $M_{g'} \approx...
