Nebular Phase Evolution of SN 2023ixf (I): From Circumstellar Infrared Echo to the onset of in-situ Dust Formation in a Type II Supernova

Avinash Singh, S. Goto, A. Sarangi +58

We present optical and near-infrared (NIR) photometric and spectroscopic observations of the Type II supernova SN 2023ixf spanning 150 to 750 days, combined with published early-ti…

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…

A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova

H. Sun, W. -X. Li, L. -D. Liu +163

Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…

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…
