Giant radio galaxies as probes of the ambient WHIM in the era of the SKA

open access: yes, 2015
The missing baryons are usually thought to reside in galaxy filaments as warm-hot intergalactic medium (WHIM). From previous studies, giant radio galaxies are usually associated with galaxy groups, which normally trace the WHIM.

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.

Astrophysical black holes: An explanation for the galaxy quenching

open access: yesJournal of High Energy Astrophysics
In light of increasing observational evidence supporting the existence of ultra-compact objects, we adopt the term astrophysical black hole to refer to any object having a huge mass confined within a sufficiently small region of spacetime. This terminology encompasses both the classical black hole solutions predicted by general relativity, as well as ...

WACCM‐X Simulation of the Atmosphere From 1950 Through 2024 at an Hourly Resolution

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Modeling of the upper atmosphere, namely the thermosphere and ionosphere, is becoming important for applications such as orbital propagation (including satellite collision avoidance), radio propagation for communications, radar and position, navigation and timing.

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

GASP XXIII: A Jellyfish Galaxy as an Astrophysical Laboratory of the Baryonic Cycle [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract With MUSE, Chandra, VLA, ALMA, and UVIT data from the GASP program, we study the multiphase baryonic components in a jellyfish galaxy (JW100) with a stellar mass 3.2 × 1011 M ⊙ hosting an active galactic nucleus (AGN).

Groups of galaxies in the Center for Astrophysics redshift survey

open access: yesThe Astrophysical Journal, 1989
By applying the Huchra and Geller (1982) objective group identification algorithm to the Center for Astrophysics' redshift survey, a catalog of 128 groups with three or more members is extracted, and 92 of these are used as a statistical sample. A comparison of the distribution of group centers with the distribution of all galaxies in the survey ...

The astrophysical consequences of intervening galaxy gas on fast radio bursts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2017
We adopt and analyze results on the incidence and physical properties of damped Ly$α$ systems (DLAs) to predict the astrophysical impact of gas in galaxies on observations of Fast Radio Bursts (FRBs). Three DLA measures form the basis of this analysis: (i) the HI column density distribution, parameterized as a double power-law; (ii) the incidence of ...

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.
