Characterising EP241107a: Multiwavelength Observations of an Einstein Probe-detected Fast X-ray Transient
D. Eappachen, A. Balasubramanian, Vishwajeet Swain +12
Fast X-ray Transients (FXTs) represent a new class of highly luminous transients in soft X-rays (0.3-10 keV) associated with violent astrophysical processes. They manifest as…

A Panchromatic View of Late-time Shock Power in the Type II Supernova 2023ixf
W. V. Jacobson-Galán, L. Dessart, C. D. Kilpatrick +39
We present multi-wavelength observations of the type II supernova (SN II) 2023ixf during its first two years of evolution. We combine ground-based optical/NIR spectroscopy with Hub…

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…
