A Multi-Wavelength View of the First Type Ic-BL Supernova with an Einstein Probe X-ray Shock Breakout
Jillian C. Rastinejad, Gokul Srinivasaragavan, Nikhil Sarin +36
In March 2026, the Einstein Probe (EP) discovered its most nearby (z = 0.0343) Fast X-ray Transient (FXT), EP260321a, the first EP FXT to provide a strong match to expectations for…
The Environments of Luminous Fast Blue Optical Transients: Evidence for a Compact Object and Wolf-Rayet Star Merger Origin
Anya E. Nugent, V. Ashley Villar, Brian D. Metzger +5
We present a comprehensive analysis of the host galaxies of 11 luminous fast blue optical transients (LFBOTs). We model new and archival host photometry and spectroscopy with Prosp…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl
Yize Dong, V. Ashley Villar, Anya Nugent +35
In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…
WINTER on S250206dm: A near-infrared search for an electromagnetic counterpart to a gravitational-wave event
Danielle Frostig, Viraj R. Karambelkar, Robert D. Stein +10
We present near-infrared follow-up observations of the International Gravitational Wave Network (IGWN) event S250206dm with the Wide-Field Infrared Transient Explorer (WINTER). WIN…
Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed
M. Pillas, S. Antier, K. Ackley +78
Neutron star-black hole (NSBH) mergers, detectable via their gravitational-wave (GW) emission, are expected to produce kilonovae (KNe). Four NSBH candidates have been identified an…
A diverse, overlooked population of Type Ia supernovae exhibiting mid-infrared signatures of delayed circumstellar interaction
Geoffrey Mo, Kishalay De, Eli Wiston +10
Type Ia supernovae arise from the thermonuclear explosions of white dwarfs in multiple star systems. A rare sub-class of SNe Ia exhibit signatures of interaction with circumstellar…
A New Population of Mid-Infrared-Selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties
Megan Masterson, Kishalay De, Christos Panagiotou +14
Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), howeve…
Multi-messenger astrophysics in the gravitational-wave era
Geoffrey Mo, Rahul Jayaraman, Danielle Frostig +3
The observation of GW170817, the first binary neutron star merger observed in both gravitational waves (GW) and electromagnetic (EM) waves, kickstarted the age of multi-messenger G…
A luminous dust-obscured Tidal Disruption Event candidate in a star forming galaxy at 42 Mpc
Christos Panagiotou, Kishalay De, Megan Masterson +11
While the vast majority of Tidal Disruption Events (TDEs) has been identified by wide-field sky surveys in the optical and X-ray bands, recent studies indicate that a considerable…
An Infrared Search for Kilonovae with the WINTER Telescope. I. Binary Neutron Star Mergers
Danielle Frostig, Sylvia Biscoveanu, Geoffrey Mo +8
The Wide-Field Infrared Transient Explorer (WINTER) is a new 1 seeing-limited time-domain survey instrument designed for dedicated near-infrared follow-up of kilonov…
The Dynamic Infrared Sky
Mansi M. Kasliwal, Scott Adams, Igor Andreoni +16
Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves fro…
