abstract

We present updated results of the Large Binocular Telescope Search for Failed Supernovae. This search monitors luminous stars in 27 nearby galaxies with a current baseline of 11~yr of data. We re-discover the failed supernova (SN) candidate N6946-BH1 as well as a new candidate, M101-OC1. M101-OC1 is a blue supergiant that rapidly disappears in optical wavelengths with no evidence for significant obscuration by warm dust. While we consider other options, a good explanation for the fading of M101-OC1 is a failed SN, but follow-up observations are needed to confirm this. Assuming only one clearly detected failed SN, we find a failed SN fraction $f = 0.16^{+0.23}_{-0.12}$ at 90 per~cent confidence. We also report on a collection of stars that show slow ($\sim$decade), large amplitude ($\Delta L/L > 3$) luminosity changes.

  1. Diffuse Supernova Neutrino Background and Neutrino Non-Radiative Decay: a Bayesian Perspective

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A Bayesian forecast of upcoming DSNB detectors shows neutrino decay can be distinguished from stability for quasi-degenerate or inverted mass patterns, but not for strong normal hierarchy.

  2. Paleodetectors for neutrino signals from diverse Galactic stellar collapses

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    Paleodetectors can reach burst-like Galactic core-collapse activity of several tens of supernovae at 10 pc, with sensitivity enhanced by high-mass NS and failed-SN neutrino emission that depends on the nuclear EOS.

  3. High-Energy Neutrinos from Cosmic-Ray Scatterings with Supernova Neutrinos

    hep-ph 2025-08 conditional novelty 5.0 of 10

    Cosmic-ray boosted supernova neutrinos could be detectable in optimistic astrophysical scenarios and yield a bound of about 30 TeV on the extra-dimensional scale.

  4. Unveiling the Milky Way with a Gaia DR3 census of OB-type stars within 2 kpc. I. Tracing local Galactic structure, massive star-forming regions and core-collapse supernova progenitors

    astro-ph.GA 2026-07 conditional novelty 4.0 of 10

    A Gaia DR3-based census of 105,971 OB stars within 2 kpc maps local Galactic structure and identifies over 4,200 core-collapse supernova or black hole progenitor candidates.

  5. Neutrinos from explosive transients at the dawn of multi-messenger astronomy

    astro-ph.HE 2024-12 unverdicted

    This review summarizes the state of neutrino emission from supernovae and neutron-star mergers, covering thermal and high-energy signals, flavor conversion, and multi-messenger detection strategies.
