Error analysis of Abel retrieved electron density profiles from radio occultation measurements [PDF]

open access: yesAnnales Geophysicae, 2010
This letter reports for the first time the simulated error distribution of radio occultation (RO) electron density profiles (EDPs) from the Abel inversion in a systematic way.

COSMIC: mining complete cancer genomes in the Catalogue of Somatic Mutations in Cancer

open access: yesNucleic Acids Res., 2010
COSMIC (http://www.sanger.ac.uk/cosmic) curates comprehensive information on somatic mutations in human cancer. Release v48 (July 2010) describes over 136 000 coding mutations in almost 542 000 tumour samples; of the 18 490 genes documented, 4803 (26 ...

Cosmic String Interpretation of NANOGrav Pulsar Timing Data. [PDF]

open access: yesPhysical Review Letters, 2020
Pulsar timing data used to provide upper limits on a possible stochastic gravitational wave background (SGWB). However, the NANOGrav Collaboration has recently reported strong evidence for a stochastic common-spectrum process, which we interpret as a ...

Leading cluster approach to simulations of hadron collisions with GHOST generator [PDF]

open access: yesEPJ Web of Conferences, 2019
The model HDPM of CORSIKA has been updated and developed on the base of the recent measurements by ALICE, CMS, TOTEM, LHCb, LHCf... The new model, GHOST, involving a four-source production reproduces correctly the pseudo-rapidity distributions of charged

Observation of an ultra-high-energy cosmic neutrino with KM3NeT

open access: yesNature
The detection of cosmic neutrinos with energies above a teraelectronvolt (TeV) offers a unique exploration into astrophysical phenomena1, 2–3. Electrically neutral and interacting only by means of the weak interaction, neutrinos are not deflected by ...

Direct detection of a break in the teraelectronvolt cosmic-ray spectrum of electrons and positrons [PDF]

open access: yesNature, 2017
High-energy cosmic-ray electrons and positrons (CREs), which lose energy quickly during their propagation, provide a probe of Galactic high-energy processes and may enable the observation of phenomena such as dark-matter particle annihilation or decay ...

The Updated Version of the A.Ne.Mo.S. GLE Alert System: The Case of the Ground-Level Enhancement GLE73 on 28 October 2021

open access: yesUniverse, 2022
A ground-level enhancement (GLE) event is a sudden increase in cosmic ray intensity originated by solar sources and recorded by ground-based detectors. GLEs are invariably associated with large solar flares that can release and accelerate solar particles

Cosmic superstrings

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
Cosmic superstrings are expected to be formed at the end of brane inflation, within the context of brane-world cosmological models inspired from string theory. By studying the properties of cosmic superstring networks and comparing their phenomenological consequences against observational data, we aim to pin down the successful and natural inflationary

Discord in Concordance Cosmology and Anomalously Massive Early Galaxies

open access: yesUniverse
Cosmological parameters are constrained by a wide variety of observations. We examine the concordance diagram for modern measurements of the Hubble constant, the shape parameter from the large-scale structure, the cluster baryon fraction, and the age of ...

Cosmic clocks, cosmic variance and cosmic averages

open access: yesNew Journal of Physics, 2007
Cosmic acceleration is explained quantitatively, purely in general relativity, as an apparent effect due to quasilocal gravitational energy differences that arise in the decoupling of bound systems from the global expansion of the universe. "Dark energy" is recognised as a misidentification of those aspects of gravitational energy which by virtue of ...
