Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
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…
Symbolic Regression Is All You Need: From Simulations to Scaling Laws in Binary Neutron Star Mergers
P. Darc, Clecio R. Bom, Charles Kilpatrick +2
Gravitational wave sources with electromagnetic counterparts have highlighted the need for predictive, interpretable models linking the parameters of compact binary systems to post…
LB-1 is inconsistent with the X-ray source population and pulsar-black hole binary searches in the Milky Way
Mohammadtaher Safarzadeh, Enrico Ramirez-Ruiz, Charles Kilpatrick
If confirmed, a wide binary system of 70 black hole (BH) and an 8 main sequence star (LB-1) is observed to reside in the Milky Way (MW). We show that long t…
The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the Ultraviolet to the Near-Infrared
Natalie LeBaron, Raffaella Margutti, Ryan Chornock +45
We present an extensive photometric and spectroscopic ultraviolet-optical-infrared campaign on the luminous fast blue optical transient (LFBOT) AT 2024wpp over the first ~100 d. AT…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
Detection of Circumstellar Helium in Type Iax Progenitor Systems
Wynn Jacobson-Galan, Ryan Foley, Josiah Schwab +6
We present direct spectroscopic modeling of 44 Type Iax supernovae (SNe Iax) using spectral synthesis code SYNAPPS. We confirm detections of helium emission in the early-time spect…
SOAR/Goodman Spectroscopic Assessment of Candidate Counterparts of the LIGO-Virgo Event GW190814
Douglas Tucker, Matthew Wiesner, Sahar Allam +140
On 2019 August 14 at 21:10:39 UTC, the LIGO/Virgo Collaboration (LVC) detected a possible neutron star-black hole merger (NSBH), the first ever identified. An extensive search for…
