Old and Bright: The Remarkable Radio Brightening of the Engine-driven SN 2012au Several Years After Explosion Signals the Birth of a PWN
Eli Wiston, Raffaella Margutti, A. J. Nayana +23
We present the results from an extensive broad-band (radio to X-rays) observing campaign of the engine-driven Type Ib SN 2012au in the first 13 years of evolution. The early-time (…
The first radio view of a type Ibn supernova in SN 2023fyq: Understanding the mass-loss history in the last decade before the explosion
Raphael Baer-Way, A. J. Nayana, Wynn Jacobson-Galan +13
Supernovae that interact with hydrogen-poor, helium-rich circumstellar material (CSM), known as Type Ibn supernovae (SNe Ibn), present a unique opportunity to probe mass-loss proce…
Delayed radio emission in tidal disruption events from collisions of outflows driven by disk instabilities
Samantha C. Wu, Daichi Tsuna, Brenna Mockler +1
Delayed radio emission has been associated with a growing proportion of tidal disruption events (TDEs). For many events, the radio synchrotron emission is inferred to originate fro…
Black Hole Survival Guide: Searching for Stars in the Galactic Center That Endure Partial Tidal Disruption
Rewa Clark Bush, Samantha C. Wu, Rosa Wallace Everson +3
Once per 10,000-100,000 years, an unlucky star may experience a close encounter with a supermassive black hole (SMBH), partially or fully tearing apart the star in an exceedingly b…
Luminous Late-time Radio Emission from Supernovae Interacting with Circumbinary Material
Samantha C. Wu, Daichi Tsuna
Numerous core-collapse supernovae (CCSNe) exhibit signatures of interaction with circumstellar material (CSM). Bright radio emission years after the SN is one such indication of de…
A Spectroscopic Hunt for Post-Red Supergiants in the Large Magellanic Cloud II: Turbulent Line Broadening in the Spectra of LMC Yellow Supergiants
Trevor Z. Dorn-Wallenstein, Kaitlyn M. Chen, Samantha C. Wu +4
Massive stars in the Hertzsprung gap are a mixed population of objects in short-lived evolutionary phases: yellow supergiants (YSGs) evolving towards the red supergiant (RSG) phase…
