LUVCam: A high-performance, low-cost, UV/optical camera for the future of astronomy in space
Aaron Tohuvavohu, Suresh Sivanandam, Jean-Christophe Fronteddu +23
Astronomy-grade cameras with robust performance and heritage in the space environment have long been costly, substantially limiting capacity for space-based astronomy and creating…
Hubble as a Unique Discovery Engine of the Fate of Massive Stars and Black Hole Formation
Avishai Gilkis, Eva Laplace, Charles D. Kilpatrick +3
How stellar-mass black holes are formed is an open question in astrophysics, with very limited observational constraints. It is not known which types of stars are more likely to pr…
Hot blue progenitors of stellar-mass black holes
Avishai Gilkis, Eva Laplace, Maria Drout +3
While the connection between massive stars and supernova explosions is well established observationally, the link between massive stars and black hole formation remains elusive. So…
A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29
We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…
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…
VLBI Observations of SN 2012au Reveal a Compact Radio Source a Decade Post Explosion
Mattias Lazda, Kenzie Nimmo, Maria R. Drout +13
Three leading models have been put forth to justify the observed radio re-brightening associated with stripped-envelope supernovae (SESNe) years post-explosion: radiation from an e…
