ICECUBE OBSERVATORY: NEUTRINOS AND THE ORIGIN OF COSMIC RAYS

Acta Polytechnica, 2013
The completed IceCube Observatory, the first km3 neutrino telescope, is already providing the most stringent limits on the flux of high energy cosmic neutrinos from point-like and diffuse galactic and extra-galactic sources.

High energy galactic gamma radiation from cosmic rays concentrated in spiral arms [PDF]

A model for the emission of high energy ( 100 MeV) gamma rays from the galactic disk was developed and compared to recent SAS-2 observations. In the calculation, it is assumed that (1) the high energy galactic gamma rays result primarily from the ...

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

TEMPO at Night: Lightning Flashes and On‐Orbit Instrument Performance

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract The abundant nighttime (twilight) spectra from October 2024 are used for characterization of on‐orbit instrument performance of the Tropospheric Emissions: Monitoring of Pollution (TEMPO, a geostationary imaging spectrometer). We select 250 lightning flashes and measure the flash sizes and flash positions in 6 spectral domains spread across ...

Sources of sub-GZK cosmic rays [PDF]

, 2002
We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real data -- (1) improvement of correlations with corrections of trajectories ...

Numerical Representation of Contemporary Atmospheric Δ14CO2: 1. Time‐Varying Global Fluxes and Atmospheric Mass Balance

Global Biogeochemical Cycles, Volume 39, Issue 11, November 2025.
Abstract Precise measurements of 14C:C in atmospheric CO2 (expressed as Δ14C) are increasingly used in contemporary carbon cycle studies as a tracer of various processes, including anthropogenic CO2 emissions from combustion of fossil fuels and cement production.
