Identification of 4876 Bent-tail Radio Galaxies in the FIRST Survey Using Deep Learning Combined with Visual Inspection

The Astrophysical Journal Supplement Series
Bent-tail radio galaxies (BTRGs) are characterized by bent radio lobes. This unique shape is mainly caused by the movement of the galaxy within a cluster, during which the radio jets are deflected by the intracluster medium.

The Role of the Magnetic Field in the Interstellar Medium of the Post-Starburst Dwarf Irregular Galaxy NGC 1569

, 2010
(abridged) NGC 1569 is a nearby dwarf irregular galaxy which underwent an intense burst of star formation 10 to 40 Myr ago. We present observations that reach surface brightnesses two to eighty times fainter than previous radio continuum observations and

What is the difference between radio galaxies and radio quasar galaxies?

The Astrophysical Journal, 1987
Deep optical imaging in the B and R band of about 50 luminous radio galaxies and radio QSOs in the redshift range 0.1-0.5 is reported. More than 80 percent of each type of object are optically interacting; about 60 percent are irregular in some way, and about 30 percent have tidal tails. Separations range from a few kpc to tens of kpc. About 30 percent

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

Journal 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.

Peculiar Galaxies and Radio Sources

Science, 1966
Pairs of radio sources which are separated by from 2° to 6° on the sky have been investigated. In a number of cases peculiar galaxies have been found approximately midway along a line joining the two radio sources. The central peculiar galaxies belong mainly to a certain class in the recently compiled Atlas of Peculiar Galaxies

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

Journal 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.

Performance of an automated insulin‐glucagon delivery system versus automated insulin delivery system during challenging inpatient conditions. A single‐blind randomised controlled crossover trial

Diabetes, Obesity and Metabolism, Volume 28, Issue 5, Page 3955-3964, May 2026.
Abstract Aims To assess the efficacy and safety of an automated insulin‐glucagon delivery system (AIGD) compared with an automated insulin delivery system (AID). Materials and methods In a 33‐h, randomised, crossover, inpatient study, 13 participants with type 1 diabetes used the DiaCon system in AIGD and AID modes.

Constraining Annihilating Dark Matter Using the Multifrequency Radio Flux Profiles of the M33 Galaxy

The Astrophysical Journal
Radio data can give stringent constraints for annihilating dark matter. In general, radio observations can detect very accurate radio flux density with high resolution and different frequencies for nearby galaxies.

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

, 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.

A Linearly Polarized Merger Shock Down to 550 MHz: A uGMRT Study of the Merging Cluster A746

The Astrophysical Journal
Radio relics, arc-like polarized sources with highly aligned magnetic fields, are typically found on the outskirts of merging galaxy clusters. The magnetoionic media responsible for the significant coherence observed in radio relics remain poorly ...
