The Host Galaxies and Progenitors of Fast Radio Bursts Localized with the Australian Square Kilometre Array Pathfinder [PDF]

open access: yes2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020
The Australian SKA Pathfinder (ASKAP) telescope has started to localize fast radio bursts (FRBs) to arcsecond accuracy from the detection of a single pulse, allowing their host galaxies to be reliably identified.

Radio Galaxies at TeV Energies

open access: yesGalaxies, 2022
Unlike blazars, radio galaxies have jets that are misaligned relative to our line-of-sight. This misaligned geometry provides us with a unique view of both the jet and super massive black hole.

Giant radio galaxies in the LOFAR Two-metre Sky Survey [PDF]

open access: yesAstronomy & Astrophysics, 2019
Giant radio galaxies (GRGs) are a subclass of radio galaxies, which have grown to megaparsec scales. GRGs are much rarer than normal-sized radio galaxies (< 0.7 Mpc) and the reason for their gigantic sizes is still debated. Here, we report on the biggest

Simulating the Enrichment of Fossil Radio Electrons by Multiple Radio Galaxies

open access: yesGalaxies, 2023
We simulate the evolution of relativistic electrons injected into the intracluster medium by five radio galaxies. We study the spatial transport and the emission properties of the injected radio plasma over a ∼5 Gyr period, and the sequence of cooling ...

The Extragalactic Gamma-Ray Background from Core-dominated Radio Galaxies [PDF]

open access: yesAstrophysical Journal, 2019
Recent radio surveys have discovered a large number of low-luminosity core-dominated radio galaxies that are much more abundant than those at higher luminosities.

Does the fir-radio correlation evolve with redshift in irregular and disk galaxies? [PDF]

open access: yesSerbian Astronomical Journal, 2021
It was confirmed that there is a strong linear correlation between the thermal far-infrared (FIR) and non-thermal radio emission of the star-forming galaxies.

General Physical Properties of Gamma-Ray-emitting Radio Galaxies

open access: yesThe Astrophysical Journal Supplement Series, 2023
We study the radio galaxies with known redshifts detected by the Fermi satellite after 10 yr of data (4FGL-DR2). We use a one-zone leptonic model to fit the quasi-simultaneous multiwavelength data of these radio galaxies and study the distributions of ...

FR0 Radio Galaxies and Their Place in the Radio Morphology Classification [PDF]

open access: yesAstrophysical Journal, 2018
So-called FR0 radio galaxies have recently emerged as a family of active galaxies with all the same properties as FRI radio galaxies except for their ratio of core to total emission, which is about 30 times higher than that of FRI sources.

What is driving the evolution of the far-infrared radio correlation? [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2019
Far infrared-radio correlation represents a linear relationship between far-infrared (FIR) and radio emission in star-forming galaxies. Previous observations have confirmed that this correlation is maintained over a large range of redshift and ...

Fornax A, Centaurus A, and other radio galaxies as sources of ultrahigh energy cosmic rays [PDF]

open access: yes, 2018
The origin of ultra-high energy cosmic rays (UHECRs) is still unknown. It has recently been proposed that UHECR anisotropies can be attributed to starbust galaxies or active galactic nuclei.
