Early panchromatic spectra reveal helium in the thermonuclear supernova 2024kce

Abigail Polin, Dillon Hasenour, Sahana Kumar +26

Faint Type I supernovae blur the boundaries between spectroscopic classes, obscuring their progenitors and explosion mechanisms. One proposed origin is a double detonation, in whic…

Characterizing the host galaxies and delay times of Ca-rich gap transients vs 91bg-like SNe and normal Type Ia SNe

Peter Scherbak, Abigail Polin, Mansi Kasliwal +4

Calcium-rich gap transients are a faint, fast-evolving class of supernovae that show strong nebular Ca emission lines. Their progenitor systems are uncertain, but they are often as…

The Search for Stable Nickel: Investigating the Origins of Type Ia Supernovae with Late-time NIR Spectroscopy from the Carnegie Supernova Project-II

Sahana Kumar, Eric Y. Hsiao, Christopher Ashall +20

Producing stable Ni in Type Ia supernovae (SNe Ia) requires sufficiently high density conditions that are not predicted for all origin scenarios, so examining the distributi…

Expansion properties of the young supernova type Iax remnant Pa 30 revealed

Tim Cunningham, Ilaria Caiazzo, Nikolaus Z. Prusinski +14

The recently discovered Pa 30 nebula, the putative type Iax supernova remnant associated with the historical supernova of 1181 AD, shows puzzling characteristics that make it uniqu…

1991T-like Supernovae

M. M. Phillips, C. Ashall, Peter J. Brown +23

Understanding the nature of the luminous 1991T-like supernovae is of great importance to supernova cosmology as they are likely to have been more common in the early universe. In t…

The Most Energetic Transients: Tidal Disruptions of High-Mass Stars

Jason T. Hinkle, Benjamin J. Shappee, Katie Auchettl +13

We present the class of extreme nuclear transients (ENTs), including the most energetic single transient yet discovered, Gaia18cdj. Each ENT is coincident with its host-galaxy nucl…

The Host Galaxies of High Velocity Type Ia Supernovae

Anya E. Nugent, Abigail E. Polin, Peter E. Nugent

In recent years, there has been ample evidence that Type Ia supernova (SNe Ia) with high Si 2 velocities near peak brightness are distinguished from SNe Ia of lower velocities and…
