This work describes the response of the IceCube Neutrino Observatory and its successive extensions to low energy neutrinos from the core collapse of progenitor stars in the kpc range. IceCube detects such bursts not through individual event reconstruction, but through a collective rise in photomultiplier rates above the dark noise floor, a reach historically estimated using a single averaged...

High-energy neutrinos are believed to be produced in cosmic accelerators as a result of hadronic interactions. Cores of active galactic nuclei are considered to be among the primary sites for cosmic-ray acceleration and neutrino production. The latter is facilitated by the dense matter and radiation in the vicinity of the supermassive black holes. The recent observation by the IceCube Neutrino...

On February 13, 2023, the KM3NeT detector, a soon-to-be cubic-kilometer neutrino telescope in the Mediterranean Sea, observed the highest-energy (~200 PeV) neutrino detected to date, designated KM3-230213A. This measurement marks an important milestone for astroparticle physics, and its origins could provide insight into the most extreme processes in the Universe. The IceCube Neutrino...

While astrophysical gamma rays and cosmic rays do not reach the ground, they generate a shower of particles when they interact in the atmosphere. This shower then generates a brief, but bright, flash of Cherenkov light. The detection of this Cherenkov light is often performed with imaging atmospheric Cherenkov telescopes (IACTs) which are incredibly large and sensitive instruments. I am...

High-energy neutrinos directly probe hadronic interactions, yet the sources of most of IceCube’s diffuse astrophysical neutrino flux remain unknown. The lack of significant point-source detections suggests that much of this flux may arise from populations of faint sources, motivating population-level searches. IceCube’s high-energy neutrino alert program enables a data-driven search for...

AGN disks may contain a population of embedded stellar-mass black holes with accretion rates limited by feedback mechanisms such as winds or jets. Here, we consider the potential for such winds to serve as sites of particle acceleration and TeV - PeV neutrino production. We employ a simple Shakura-Sunyaev AGN disk model harboring a population of embedded stellar-mass black holes. These black...

The flavor composition of high-energy astrophysical neutrinos encodes information about their production and propagation. The Glashow resonant interaction $\bar{\nu}e+e^-\to W^-$, provides a unique way to distinguish antineutrinos from neutrinos, which extends the reach of flavor composition studies. Proposed tau air-shower neutrino telescopes target Earth-skimming and mountain-skimming...
