High-Energy and Ultra-High-Energy Neutrino Astrophysics
UniverseThe origin of high-energy cosmic rays, and their behavior in astrophysical sources, remains an open question. Recently, new ways to address this question have been made possible by the observation of a new astrophysical messenger, namely neutrinos.

High-Energy Astrophysics in the 2020s and Beyond [PDF]
, 2019 With each passing decade, we gain new appreciation for the dynamic, connected, and often violent nature of the Universe. This reality necessarily places the study of high-energy processes at the very heart of modern astrophysics.

Discovery of VHE and HE emission from the blazar 1ES 0414+009 with H.E.S.S and Fermi-LAT
, 2011 The high energy peaked BL Lac (HBL) object 1ES 0414+009 (z=0.287) is a distant very high-energy (VHE, E > 100 GeV) blazars with well-determined redshift.

Best-Bet Astrophysical Neutrino Sources [PDF]
, 2006 Likely astrophysical sources of detectable high-energy (>> TeV) neutrinos are considered. Based on gamma-ray emission properties, the most probable sources of neutrinos are argued to be GRBs, blazars, microquasars, and supernova remnants.

HIGH-ENERGY ASPECTS OF ASTROPHYSICAL JETS [PDF]
International Journal of Modern Physics A, 2006 Various aspects of the high-energy emission from relativistic jets associated with compact astrophysical systems are reviewed. The main leptonic and hadronic processes responsible for the production of high-energy γ-rays, very-high-energy neutrinos and ultra-high energy cosmic rays are discussed.

High-Energy Neutrino Astrophysics [PDF]
Annual Review of Nuclear and Particle Science, 2000 ▪ Abstract High-energy (>100 MeV) neutrino astrophysics enters an era of opportunity and discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We review the major challenges for this emerging field, among which the nature of dark matter, the origin of cosmic rays, and the physics of extreme objects such as ...

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Delensing for precision cosmology: optimizing future CMB B-mode surveys to constrain r
European Physical Journal C: Particles and FieldsThe detection of primordial B-modes, a key probe of cosmic inflation, is increasingly challenged by contamination from weak gravitational lensing B-modes induced by large-scale structure (LSS).

Deformed Lorentz Symmetry and High-Energy Astrophysics (II) [PDF]
, 2000 Lorentz symmetry violation (LSV) can be generated at the Planck scale, or at some other fundamental length scale, and naturally preserve Lorentz symmetry as a low-energy limit (deformed Lorentz symmetry, DLS).

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.
