Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny
Willem B. Hoogendam, David O. Jones, Christopher J. Storfer +26
We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at . We use integral-field Keck-II/…
AT2025agpz in Rubin commissioning data: distinguishing a luminous interacting supernova from nuclear transients in compact galaxies
C. R. Angus, M. Quilt, H. F. Stevance +37
The Vera C. Rubin Observatory's Legacy Survey of Space and Time will discover unprecedented numbers of rare, long-lived optical transients, many of which will be too faint or too n…
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…
AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera
Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25
As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
Searching for Neutron Star Mergers in the Absence of Gravitational Waves with Optical Afterglow Emission
Haille M. L. Perkins, Gautham Narayan, Brian D. Fields +2
With the forth observing run of the LIGO-Virgo-KAGRA gravitational-wave network, which enabled the discovery of the kilonova (KN) counterpart to GW170817, ending with no new confir…
Predictions for Electromagnetic Counterparts to Neutron Star Mergers Discovered during LIGO-Virgo-KAGRA Observing Runs 4 and 5
Ved G. Shah, Gautham Narayan, Haille M. L. Perkins +4
We present a comprehensive, configurable open-source framework for estimating the rate of electromagnetic detection of kilonovae (KNe) associated with gravitational wave detections…
Could a Kilonova Kill: a Threat Assessment
Haille M. L. Perkins, John Ellis, Brian D. Fields +5
Binary neutron star mergers (BNS) produce high-energy emissions from several physically different sources, including a gamma-ray burst (GRB) and its afterglow, a kilonova, and, at…
