We analyze pre-explosion near-and mid-infrared (IR) imaging of the site of SN 2023ixf in the
nearby spiral galaxy M101 and characterize the candidate progenitor star. The star displays …

The current standard model of cosmology successfully describes a variety of measurements,
but the nature of its main ingredients, dark matter and dark energy, remains unknown. is a …

Observational evidence points to a red supergiant (RSG) progenitor for SN 2023ixf. The
progenitor candidate has been detected in archival images at wavelengths (≥ 0.6 μm) …

We present the unTimely Catalog, a deep time-domain catalog of detections based on Wide-
field Infrared Survey Explorer (WISE) and NEOWISE observations spanning the 2010 …

Supernova (SN) explosions have been sought for decades as a possible source of dust in
the Universe, providing the seeds of galaxies, stars, and planetary systems. SN 1987A offers …

We present extensive datasets for a class of intermediate-luminosity optical transients
known as luminous red novae. They show double-peaked light curves, with an initial rapid …

The process of unstable mass transfer in a stellar binary can result in either a complete
merger of the stars or successful removal of the donor envelope leaving a surviving more …

Luminous red novae (LRNe) are astrophysical transients associated with the partial ejection
of a binary system's common envelope shortly before its merger. Here we present the results …

Binary stars commonly pass through phases of direct interaction, which result in the rapid
loss of mass, energy, and angular momentum. Though crucial to understanding the fates of …

Luminous red novae (LRN) are a class of optical transients believed to originate from the
mergers of binary stars, or 'common envelope'events. Their light curves often show …
