Duty cycle of the radio galaxy B2 0258+35 [PDF]
Astronomy & Astrophysics, 2018 Context. Radio loud active galactic nuclei (AGN) are episodic in nature, cycling through periods of activity and quiescence. The study of this duty cycle has recently gained new relevance because of the importance of AGN feedback for galaxy evolution ...

Particle content, radio-galaxy morphology and jet power : all radio-loud AGN are not equal [PDF]
, 2018 Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGN) throughout cosmic time; however, there remain major uncertainties in translating radio luminosity functions into a reliable ...

FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022 Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

High energy emission component, population, and contribution to the extragalactic gamma-ray background of gamma-ray emitting radio galaxies [PDF]
, 2022 In this study, we systematically studied the X-ray to GeV gamma-ray spectra of 61 {\it Fermi} Large Area Telescope (LAT) detected radio galaxies. We found an anticorrelation between peak frequency and peak luminosity in the high-energy spectral component of radio galaxies, similar to blazars. With this sample, we also constructed a gamma-ray luminosity

Radio Galaxy Zoo: machine learning for radio source host galaxy cross-identification [PDF]
, 2018 We consider the problem of determining the host galaxies of radio sources by cross-identification. This has traditionally been done manually, which will be intractable for wide-area radio surveys like the Evolutionary Map of the Universe. Automated cross-

A single fast radio burst localized to a massive galaxy at cosmological distance [PDF]
Science, 2019 Pinpointing a single fast radio burst Fast radio bursts (FRBs) are flashes of radio emission from distant astronomical sources. Two FRBs are known to have repeated, but most last just a few milliseconds and are never seen again.

Multifrequency analysis of the radio emission from a post-merger galaxy CGCG 292-057 [PDF]
, 2023 Galaxies exhibiting a specific large-scale extended radio emission, such as X-shaped radio galaxies, belong to a rare class of winged radio galaxies. The morphological evolution of these radio sources is explained using several theoretical models, including galaxy mergers.

LOFAR discovery of an ultra-steep radio halo and giant head–tail radio galaxy in Abell 1132 [PDF]
, 2017 Low-Frequency Array (LOFAR) observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of similar to 650 kpc near the cluster centre and a head-tail (HT ...

Diffuse Radio Emission from Galaxy Clusters [PDF]
Space Science Reviews, 2019 In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies.
