The New Status Qvo? SN 2021qvo is Another 2003fg-like Type Ia Supernova with a Rising Light-Curve Bump

I. A. Abreu Paniagua, W. B. Hoogendam, D. O. Jones +24

In recent years, multiple Type Ia supernovae (SNe Ia) have been observed with ''bumps'' in their rising light curves shortly after explosion. Here, we present SN 2021qvo: a SN Ia t…

Effect of positronium on the $γ$ -ray spectra and energy deposition in Type Ia supernovae

Anirban Dutta, Andrew Fullard, Wolfgang Kerzendorf +5

Type Ia supernovae (SNe Ia) are powered by the radioactive decay of isotopes such as $^{56}$ Ni and $^{56}$ Co, making their $γ$ -ray spectra useful probes of the explosion mechanism…
