The Evolution of Neutrino Astronomy

open access: yes, 2000
How did neutrino astronomy evolve? Are there any useful lessons for astronomers and physicists embarking on new observational ventures today? We answer the first question; the reader can can decide if there are any useful parallels for other fields ...

Neutrino Astronomy with MACRO

open access: yesNuclear Physics B - Proceedings Supplements, 2002
High energy neutrinos from astrophysical sources can be detected as upward-going muons produced in charged-current interactions with the matter surrounding the detector. We present the results of a search for either a diffuse astrophysical neutrino flux or a point-like source of neutrinos in the sample of upward-going muons gathered by MACRO.

Magnetic Precursor to the Structural Phase Transition in V2O3

open access: yesAdvanced Electronic Materials, Volume 11, Issue 12, August 6, 2025.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

Cosmic Bulk Flow Analysis in Modified Gravity Theories: f(R) and Perturbed f(R) Models with Neutrino Coupling

open access: yesThe Astronomical Journal
In this study, we explore the characteristics of bulk flow across various redshift ranges within the frameworks of f ( R ) gravity, perturbed f ( R ) gravity, and perturbed f ( R ) gravity coupled with neutrinos.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Neutrinos and Gamma Rays from Galaxy Clusters Constrained by the Upper Limits of IceCube

open access: yesThe Astrophysical Journal
Clusters of galaxies possess the capability to accelerate cosmic rays (CRs) to very high energy up to ∼10 ^18 eV due to their large size and magnetic field strength, which favor CR confinement for cosmological times.

Multi-Messenger Connection in High-Energy Neutrino Astronomy

open access: yesUniverse
Low fluxes of astrophysical neutrinos at TeV energies, and the overwhelming background of atmospheric neutrinos below that, render the current paradigm of neutrino astronomy a severely statistics-limited one.

Double Beta Decay Experiments With Loaded Liquid Scintillator

open access: yesFrontiers in Physics, 2019
Liquid scintillator detectors have many properties which are highly advantageous for neutrino research at the MeV energy scale. There are various choices of additives to an organic liquid scintillator which typically function as the nuclear targets in a ...

Mimicking diffuse supernova antineutrinos with the Sun as a source

open access: yes, 2009
Measuring the electron antineutrino component of the cosmic diffuse supernova neutrino background (DSNB) is the next ambitious goal for low-energy neutrino astronomy. The largest flux is expected in the lowest accessible energy bin.

Search for Neutrino Doublets and Triplets Using 11.4 yr of IceCube Data

open access: yesThe Astrophysical Journal
We report a search for high-energy astrophysical neutrino multiplets, detections of multiple neutrino clusters in the same direction within 30 days, based on an analysis of 11.4 yr of IceCube data.
