Recent results will be reviewed from IceCube, including refined measurements of the cosmic neutrino spectrum and the recent observations of neutrinos from the nearby galaxy M77 and the Milky Way. I will report on the design and construction progress of the IceCube Upgrade, which includes seven strings of dense instrumentation in the center of the IceCube. I will also discuss the design and...
The discovery of TeV-PeV astrophysical neutrinos in 2013 by IceCube precipitated the decade of spectacular progress in which we thrive today. So far, we have found the first extragalactic transient and steady-state sources of high-energy astrophysical neutrinos, plus neutrinos from comparatively nearby, the Galactic Plane. I will review these discoveries, what we have learned about the first...
Multmessenger follow-up observations triggered by high-energy neutrino signals offer a robust method for identifying cosmic ray (CR) sources, particularly when the sources are transient. In this talk, we propose a viable strategy for multimessenger observations to understand the origin of CRs. Optical transients, such as core-collapse supernovae, are among the major candidates for CR and...
The blazar TXS 0506+056 is a candidate of high-energy neutrino sources. We propose that its neutrino emission could originate from the core region rather than the jet. We suggests that high-energy protons, accelerated by magnetic reconnection within a magnetically arrested disk (MAD) near the central black hole, interact with photons from the accretion disk and corona to produce neutrinos.
Over the last two decades, several breakthroughs have been made in multi-messenger astronomy, such as the successful observations of astrophysical neutrinos and very-high-energy gamma rays. However, the origin of cosmic rays is still mystery. No neutrino source has been significantly identified due to the lack of statistics and uncovered field of view. The next generation of high-energy...
The High-energy Underwater Neutrino Telescope (HUNT) is proposed to detect the neutrinos from LHAASO sources with significant gamma-ray emission above 100 TeV and identify the PeV cosmic-ray accelerators in our Galaxy. HUNT project has made substantial advancements in the simulations and pathfinder experiments over the past year. This report will briefly introduce the simulation framework...
Atmospheric neutrinos are significant signals for studying neutrino oscillation physics and also serve as important backgrounds in the searches for diffuse supernova neutrino background, proton decay, dark matter and other rare processes. To address the unknown questions in neutrino oscillation physics and to discover rare events, accurate predictions of atmospheric neutrino flux in the GeV...
The memory burden effect, which stabilizes systems by storing information, plays a key role in black holes, where evaporation halts after roughly half the initial mass is lost. This suggests that light primordial black holes (PBHs) with mass below 10^15 g, expected to have fully evaporated, may still be viable dark matter (DM) candidates. We show that their mergers could form "young" black...
