Nonthermal Emissions from a Head–Tail Radio Galaxy in 3D Magnetohydrodynamic Simulations

The Astrophysical Journal, 2023
We present magnetohydrodynamic simulations of a jet–wind interaction in a galaxy cluster and the radio to gamma-ray and neutrino emissions from this “head–tail galaxy.” Our simulation follows the evolution of cosmic-ray (CR) particle spectra with energy ...

Simultaneous Radio Occultation Predictions for Inter-Satellite Comparison of Bending Angle Profiles from COSMIC-2 and GeoOptics

Remote Sensing, 2021
The Global Navigation Satellite System (GNSS) radio occultation (RO) is a remote sensing technique that uses International System of Units (SI) traceable GNSS signals for atmospheric limb soundings.

Inverse Compton Scattering as the Source of Diffuse EUV Emission in the Coma Cluster of Galaxies [PDF]

, 1998
We have examined the hypothesis that the majority of the diffuse EUV flux in the Coma cluster is due to inverse Compton scattering of low energy cosmic ray electrons (0.16 < epsilon < 0.31 GeV) against the 3K black-body background. We present data on the

Multi-instrument observations of ionospheric super plasma bubbles in the European longitude sector during the 23–24 April 2023 severe geomagnetic storm

Journal of Space Weather and Space Climate
This study’s objective is to better specify the rare occurrence of super equatorial plasma bubbles in particular to the European longitude sector, detailing their spatio-temporal evolution, and better understanding pre-conditions for their development ...

On the heliolatitudinal variation of the galactic cosmic-ray intensity. Comparison with Ulysses measurements [PDF]

Annales Geophysicae, 2003
We study the dependence of cosmic rays with heliolatitude using a simple method and compare the results with the actual data from Ulysses and IMP spacecraft.

Forecast Impact of FORMOSAT‐7/COSMIC‐2 GNSS Radio Occultation Measurements

Atmospheric Science Letters, 2020
The FORMOSAT‐7/COSMIC‐2 GNSS‐RO mission was launched on June 25, 2019, and it has provided a large increase in the number of GNSS‐RO observations available for operational numerical weather prediction (NWP) in the latitude band between ±40°. A key aim of

COSMOS2020: Exploring the Dawn of Quenching for Massive Galaxies at 3 < z < 5 with a New Color-selection Method

The Astronomical Journal, 2023
We select and characterize a sample of massive (log( M _* / M _⊙ ) > 10.6) quiescent galaxies (QGs) at 3 < z < 5 in the latest Cosmological Evolution Survey catalog (COSMOS2020).

Chromosomal breaks at the origin of small tandem DNA duplications

BioEssays, Volume 45, Issue 1, January 2023., 2023
Small tandem DNA duplications form a specific mutational signature frequently found in human disease alleles and cancer genes. Here we hypothesize that these duplications mainly arise at chromosomal DNA breaks that result from two closely located single‐stranded nicks, through error‐prone repair by the non‐homologous end‐joining pathway. Abstract Small

Equatorial Waves, Diurnal Tides and Small‐Scale Thermal Variability in the Tropical Lower Stratosphere From COSMIC‐2 Radio Occultation

Journal of Geophysical Research: Atmospheres, 2020
A new constellation of radio occultation satellites called COSMIC‐2 (Constellation Observing System for Meteorology, Ionosphere, and Climate‐2) is providing unprecedented dense measurements of the tropical atmosphere, with on average more than 4,000 high
