Why Are Radio-Galaxies Prolific Producers of Type Ia Supernovae? [PDF]

, 2005
An analysis of SNIa events in early type galaxies from the Cappellaro et al (1999) database provides conclusive evidence that the rate of type Ia Supernovae (SNe) in radio-loud galaxies is about 4 times higher than the rate measured in radio-quiet ...

A case for radio galaxies as the sources of IceCube's astrophysical neutrino flux [PDF]

, 2016
We present an argument that radio galaxies (active galaxies with mis-aligned jets) are likely to be the primary sources of the high-energy astrophysical neutrinos observed by IceCube.

Cosmological Studies with Radio Galaxies and Supernovae [PDF]

, 2008
Physical sizes of extended radio galaxies can be employed as a cosmological "standard ruler", using a previously developed method. Eleven new radio galaxies are added to our previous sample of nineteen sources, forming a sample of thirty objects with ...

LeMMINGs - I. The eMERLIN legacy survey of nearby galaxies. 1.5-GHz parsec-scale radio structures and cores [PDF]

, 2018
We present the first data release of high-resolution (≤0.2 arcsec) 1.5-GHz radio images of 103 nearby galaxies from the Palomar sample, observed with the eMERLIN array, as part of the LeMMINGs survey.

A pilot study of the radio-emitting AGN population: the emerging new class of FR0 radio-galaxies [PDF]

, 2015
We present the results of a pilot JVLA project aimed at studying the bulk of the radio-emitting AGN population, unveiled by the NVSS/FIRST and SDSS surveys.We obtained A-array observations at the JVLA at 1.4, 4.5, and 7.5 GHz for 12 sources of the SDSS ...

Radio Galaxies at TeV Energies: Preface

Galaxies, 2020
The majority of the known extragalactic sky from TeV gamma-ray energies consists of blazars having plasma jets pointing in the direction of the line-of-sight, which results in a large Doppler boosting of their emission.

Radio Galaxy Classification: #Tags, Not Boxes

Galaxies, 2021
After six decades of studying radio galaxies, we are now delightfully overwhelmed by their exponentially expanding numbers and the complexity of their structures.

Radio Continuum Emission at 1.4 GHz from KISS Emission-Line Galaxies

, 2004
We have searched the Faint Images of the Radio Sky at Twenty centimeters (FIRST) and the NRAO VLA Sky Survey (NVSS) 1.4 GHz radio surveys for sources that are coincident with emission-line galaxy (ELG) candidates from the KPNO International Spectroscopic

The LOFAR window on star-forming galaxies and AGNs - curved radio SEDs and IR-radio correlation at 0 [PDF]

, 2017
We present a study of the low-frequency radio properties of star-forming (SF) galaxies and active galactic nuclei (AGNs) up to redshift z = 2.5. The new spectral window probed by the Low Frequency Array (LOFAR) allows us to reconstruct the radio ...
