Characterization of the Three-Flavor Composition of Cosmic Neutrinos with IceCube

R. Abbasi, M. Ackermann, J. Adams, S. K. Agarwalla et autres

The flavor composition of cosmic neutrinos probes both the physical properties of their sources and oscillations over energies and distances unreachable by terrestrial experiments. Using 11.4 yr of IceCube data, we analyze the flavor composition of the all-sky neutrino flux from 5 …

Limiting the Parameter Space for Unstable eV-Scale Neutrinos Using IceCube Data

R. U. Abbasi, M. Ackermann, J. Adams, S. K. Agarwalla et autres

This Letter extends a recent IceCube sterile neutrino search to include unstable sterile neutrinos within the context of a model termed 3+1+Decay, which expands upon the 3+1 model by introducing sterile neutrino decay to invisible particles with coupling constant g^{2}. The model …

IceCube Search for Neutrino Emission from X-Ray Bright Seyfert Galaxies

Rasha U. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract The recent IceCube detection of TeV neutrino emission from the nearby active galaxy NGC 1068 suggests that active galactic nuclei (AGNs) could make a sizable contribution to the diffuse flux of astrophysical neutrinos. The absence of TeV γ -rays from NGC …

Search for Unstable Sterile Neutrinos with the IceCube Neutrino Observatory

M. Ackermann, J. Adams, J. A. Aguilar, M. Ahlers et autres

We present a search for an unstable sterile neutrino by looking for a resonant signal in eight years of atmospheric ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ data collected from 2011 to 2019 at the IceCube Neutrino Observatory. Both the (stable) three-neutrino and the $3+1$ sterile neutrino models …
