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…
JWST Reveals Large Reservoirs of Dust and Ongoing Circumstellar Interaction in SN Ibn/Icn 2023xgo over a Year Post-Explosion
Kyle W. Davis, Kirsty Taggart, Samaporn Tinyanont +23
We present infrared (IR) photometric and spectroscopic observations of SN 2023xgo, a recent and nearby Type Ibn/Icn supernova (SN Ibn/Icn) which shows shock interaction with a He/C…
Hot blue progenitors of stellar-mass black holes
Avishai Gilkis, Eva Laplace, Maria Drout +7
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…
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…
Near-Infrared and Optical Observations of SN 2024rbc: The First Early Detection of CO and Dust in a Type Ib Supernova
Ryan Hwangbo, Jeonghee Rho, Aravind P. Ravi +16
We present optical and near-infrared (NIR) observations of the Type Ib supernova (SN) 2024rbc. Emission from the first CO overtone, resting on a dust continuum at m, w…
Optical/infrared observations of the extraordinary GRB 250702B: a highly obscured afterglow in a massive galaxy consistent with multiple possible progenitors
Jonathan Carney, Igor Andreoni, Brendan O'Connor +31
GRB 250702B was the longest gamma-ray burst ever detected, with a duration that challenges standard collapsar models and suggests an exotic progenitor. We collected a rich set of o…
Long-Term Optical Follow Up of S231206cc: Multi-Model Constraints on BBH Merger Emission in AGN Disks
P. Darc, C. R. Bom, C. D. Kilpatrick +9
The majority of gravitational wave events detected by the LIGO, Virgo, and KAGRA Collaboration originate from binary black hole (BBH) mergers, for which no confirmed electromagneti…
An extremely soft and weak fast X-ray transient associated with a luminous supernova
W. -X. Li, Z. -P. Zhu, X. -Z. Zou +101
Long gamma-ray bursts (LGRBs), including their subclasses of low-luminosity GRBs (LL-GRBs) and X-ray flashes (XRFs) characterized by low spectral peak energies, are known to be ass…
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…
Uniform Modeling of Observed Kilonovae: Implications for Diversity and the Progenitors of Merger-Driven Long Gamma-Ray Bursts
J. C. Rastinejad, W. Fong, C. D. Kilpatrick +2
We present uniform modeling of eight kilonovae, five following short gamma-ray bursts (GRBs; including GRB170817A) and three following long GRBs. We model their broadband afterglow…
The S-PLUS Transient Extension Program: Imaging Pipeline, Transient Identification, and Survey Optimization for Multi-Messenger Astronomy
A. Santos, C. D. Kilpatrick, C. R. Bom +9
We present the S-PLUS Transient Extension Program (STEP): a supernova and fast transient survey conducted in the southern hemisphere using data from the Southern Photometric Local…
A Hubble Space Telescope Search for r-Process Nucleosynthesis in Gamma-ray Burst Supernovae
J. C. Rastinejad, W. Fong, A. J. Levan +23
The existence of a secondary (in addition to compact object mergers) source of heavy element (-process) nucleosynthesis, the core-collapse of rapidly-rotating and highly-magneti…
Kilonova Spectral Inverse Modelling with Simulation-Based Inference: An Amortized Neural Posterior Estimation Analysis
P. Darc, Clecio R. Bom, Bernardo M. O. Fraga +1
Kilonovae represent a category of astrophysical transients, identifiable as the electromagnetic observable counterparts associated with the coalescence events of binary systems com…
Interaction between Cassiopeia A and Nearby Molecular Clouds
Charles D. Kilpatrick, John H. Bieging, George H. Rieke
We present spectroscopy of the supernova remnant Cassiopeia A (Cas A) observed at infrared wavelengths from 10 - 40 micron with the Spitzer Space Telescope and at millimeter wavele…
