Probing the Nature of the Circumstellar Material Surrounding SN 2024ggi: A Search for Precursor Emission and Constraints from Radio Observations

Tobias Géron, James K. Leung, Maria R. Drout +8

We present an analysis of the pre-explosion optical light curve and post-explosion radio observations of the nearby supernova (SN) 2024ggi, a Type II SN discovered in NGC 3621 at a…

Radio and X-ray Observations of the Transitional Supernova 2019yvr: Insights into the Progenitor Mass-Loss History

Raphael Baer-way, Raphael Baer-Way, Poonam Chandra +8

The final life stages of the massive star progenitors of stripped-envelope supernovae (SESNe) are still an open question, especially when it comes to the timing and magnitude of th…

The radio re-brightening of the Type IIb SN 2001ig

Roberto Soria, Thomas D. Russell, Eli Wiston +5

We study the late-time evolution of the compact Type IIb SN 2001ig in the spiral galaxy NGC 7424, with new and unpublished archival data from the Australia Telescope Compact Array…

Late-Time Supernovae Radio Re-brightening in the VAST Pilot Survey

Kovi Rose, Assaf Horesh, Tara Murphy +12

We present our analysis of supernovae serendipitously found to be radio-bright several years after their optical discovery. We used recent observations from the Australian SKA Path…

Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq

Jeniveve Pearson, David J. Sand, Peter Lundqvist +85

We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…

Bridging between type IIb and Ib supernovae: SN IIb 2022crv with a very thin Hydrogen envelope

Anjasha Gangopadhyay, Keiichi Maeda, Avinash Singh +26

We present optical, near-infrared, and radio observations of supernova (SN) SN~IIb 2022crv. We show that it retained a very thin H envelope and transitioned from a SN~IIb to a SN~I…
