Geophysics and Thermodynamics at South Pole Lake Indicate Stability and a Regionally Thawed Bed

Geophysical Research Letters, Volume 49, Issue 2, 28 January 2022., 2022
Abstract Subglacial lakes require a thawed bed either now or in the past; thus, their presence and stability have implications for current and past basal conditions, ice dynamics, and climate. Here, we present the most extensive geophysical exploration to date of a subglacial lake near the geographic South Pole, including radar‐imaged stratigraphy ...

Boosted Tau Lepton as a Microscope and Macroscope

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
Anomalies from the LHCb lepton flavour universality and Fermilab muon anomalous magnetic moment show tantalizing hints of possible new physics from the lepton sectors. Due to its large mass and shorter lifetime than muon, the tau lepton is believed to couple more to possible new physics beyond the Standard Model.

Quantitative Risk Assessment of a Large‐Scale Central Spherical Detector System by an Improved Fuzzy Fault Tree Analysis

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Central spherical detector is one of the most essential and complicated support systems for the large‐scale underground neutrino observatory. If a central spherical detector accident happens, the consequences may be disastrous with huge economic loss. However, there is very few published research works which focus on its quantitative risk analysis.

The Nonsymmetric Flavor Transition Matrix and the Apparent P Violation

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
The leptonic mixing parameters of high precision and the next‐generation neutrino telescopes make it possible to test new physics in the flavor transition of the high‐energy astrophysical neutrinos (HAN). We introduce a nonsymmetric matrix to modify the predictions of the standard flavor transition matrix.

Modeling Particle Transport in Astrophysical Outflows and Simulations of Associated Emissions from Hadronic Microquasar Jets

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In this work, after improving the formulation of the model on particle transport within astrophysical plasma outflows and constructing the appropriate algorithms, we test the reliability and effectiveness of our method through numerical simulations on well‐studied galactic microquasars as the SS 433 and the Cyg X‐1 systems.

High‐Energy Neutrinos from the Cosmos

Annalen der Physik, Volume 533, Issue 11, November 2021., 2021
The IceCube Neutrino Observatory is the first detector of its kind, designed to observe the cosmos from deep within the South Pole ice. It consists of a cubic kilometer of instrumented transparent ice transformed into a Cherenkov detector. IceCube's first decade of operations has yielded breakthrough results, including the discovery of very high energy

Neutrinoastronomie in der Antarktis

Physik in unserer Zeit, Volume 52, Issue 2, Page 66-72, March 2021., 2021
Vor zehn Jahren ging in der Antarktis das Neutrinoteleskop IceCube in Betrieb. Bis heute wurden damit über hundert Neutrinos von kosmischen „Beschleunigern” nachgewiesen. In einem Fall ließ sich eine aktive Galaxie als mögliche Quelle identifizieren. Zusammenfassung Fast hundert Jahre nach der Vorhersage von Neutrinos sind wir heute in der Lage, diese ...

A Cross-correlation Study between IceCube Neutrino Events and the FERMI Unresolved Gamma-Ray Sky

The Astrophysical Journal, 2023
With the coincident detections of electromagnetic radiation together with gravitational waves (GW170817) or neutrinos (TXS 0506+056), the new era of multimessenger astrophysics has begun.

Angular power spectrum analysis on current and future high-energy neutrino data [PDF]

, 2019
Astrophysical neutrino events have been measured in the last couple of years, which show an isotropic distribution, and the current discussion is their astrophysical origin. We use both isotropic and anisotropic components of the diffuse neutrino data to
