Additional candidate sources among Seyfert galaxies, reinforcing the idea that gamma-ray obscured sources are the primary contributors to the high-energy neutrino flux

🔔📜 Two IceCube papers submitted to ApJ!

We searched for neutrino emission from active galactic nuclei (AGNs) bright in X-rays. Both results support the idea that AGNs are promising high-energy neutrino emitters.

A big congratulations to Professor Francis Halzen on being elected to the @theNASciences National Academy of Sciences! 🎉

🔔📜 IceCube paper published in @NaturePhysics!

We tested for neutrino decoherence as a result of small fluctuations in spacetime caused by quantum gravity. We set the world's strongest constraints on neutrino-quantum gravity interactions.

IceCube search for sub-TeV emission from GRBs

[IceCube Neutrino Observatory @uw_icecube]

🔔📜 IceCube paper submitted to ApJ!

We present the first neutrino search from gamma-ray bursts using low-energy neutrinos. The searches looked at a gamma-ray burst catalog and also at GRB 221009A. No evidence of neutrino emission was found.

🔔📜 IceCube paper submitted to ApJ!

We searched for extended neutrino sources in the Milky Way along with the highest energy gamma-ray sources. Although not a source, the most significant location coincided with 3HWC J1951+266.

🔔📜 IceCube paper submitted to PRD!

For the first time, we did a spectral search of monochromatic neutrino lines from dark matter annihilation and decay. No signal was found, but new upper limits were set.
