Life in the Bubble: How a Nearby Supernova Left Ephemeral Footprints on the Cosmic-Ray Spectrum and Indelible Imprints on Life
Caitlyn Nojiri, Noémie Globus, Enrico Ramirez-Ruiz
The Earth sits inside a 300pc-wide void that was carved by a series of supernova explosions that went off tens of millions of years ago, pushing away interstellar gas and creating…
SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova
D. Farias, C. Gall, G. Narayan +29
We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…
A second radio flare from the tidal disruption event AT2020vwl: a delayed outflow ejection?
A. J. Goodwin, A. Mummery, T. Laskar +12
We present the discovery of a second radio flare from the tidal disruption event (TDE) AT2020vwl via long-term monitoring radio observations. Late-time radio flares from TDEs are b…
Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models
C. R. Angus, S. E. Woosley, R. J. Foley +35
We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…
Eight Years of Light from ASASSN-15oi: Towards Understanding the Late-time Evolution of TDEs
A. Hajela, K. D. Alexander, R. Margutti +26
We present the results from an extensive follow-up campaign of the Tidal Disruption Event (TDE) ASASSN-15oi spanning d, offering an unprecedented window into t…
An Optical Gamma-Ray Burst Catalogue with Measured Redshift PART I: Data Release of 535 Gamma-Ray Bursts and Colour Evolution
M. G. Dainotti, B. De Simone, R. F. Mohideen Malik +49
We present the largest optical photometry compilation of Gamma-Ray Bursts (GRBs) with redshifts (). We include 64813 observations of 535 events (including upper limits) from 28…
