We present the discovery of the Type II supernova SN 2023ixf in M101 and follow-up
photometric and spectroscopic observations, respectively, in the first month and week of its …

We present the optical spectroscopic evolution of SN 2023ixf seen in subnight cadence
spectra from 1.18 to 15 days after explosion. We identify high-ionization emission features …

We present six epochs of optical spectropolarimetry of the Type II supernova (SN) 2023ixf
ranging from∼ 2 to 15 days after the explosion. Polarimetry was obtained with the Kast …

We present early-phase panchromatic photometric and spectroscopic coverage spanning
the far-ultraviolet to near-infrared regime of the nearest hydrogen-rich core-collapse …

We present a series of high-resolution echelle spectra of SN 2023ixf in M101, obtained
nightly during the first week or so after discovery using PEPSI on the Large Binocular …

The early evolution of a supernova (SN) can reveal information about the environment and
the progenitor star. When a star explodes in vacuum, the first photons to escape from its …

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 perform a comprehensive search for optical precursor emission at the position of SN
2023ixf using data from the DLT40, ZTF, and ATLAS surveys. By comparing the current data …

As one of the closest supernovae (SNe) in the last decade, SN 2023ixf is an unprecedented
target to investigate the progenitor star that exploded. However, there is still significant …

The Fermi-LAT observations of SN 2023ixf, a type II supernova in the nearby Pinwheel
Galaxy, Messier 101 (M101), presents us with an excellent opportunity to constrain MeV …
