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

A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High-resolution Radio Observations [PDF]
Astrophysical Journal, 2019 We present a sample of nearby dwarf galaxies with radio-selected accreting massive black holes (BHs), the majority of which are non-nuclear. We observed 111 galaxies using sensitive, high-resolution observations from the Karl G.

Radio galaxy zoo EMU: towards a semantic radio galaxy morphology taxonomy
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present a novel natural language processing (NLP) approach to deriving plain English descriptors for science cases otherwise restricted by obfuscating technical terminology. We address the limitations of common radio galaxy morphology classifications by applying this approach.

FR0CAT: a FIRST catalog of FR0 radio galaxies [PDF]
, 2017 With the aim of exploring the properties of the class of FR0 radio galaxies, we selected a sample of 108 compact radio sources, called FR0CAT, by combining observations from the NVSS, FIRST, and SDSS surveys. The catalog includes sources with z$\leq 0.05$

Morphological-based Analyses for Parameterizing Symmetry in Radio Galaxies
The Astronomical Journal, 2023 The morphology of radio galaxies can provide significant clues to describe the formation and evolution of galaxies in the Universe. Here, we aim to extract the morphological parameters of radio galaxies and define symmetry criteria as some of the ...

The nuclear properties and extended morphologies of powerful radio galaxies: the roles of host galaxy and environment [PDF]
, 2017 Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff--Riley (FR) type I and II sources. FRI/II and compact radio galaxies have also been classified

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

Radio Galaxy Zoo: giant radio galaxy classification using multidomain deep learning [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT In this work we explore the potential of multidomain multibranch convolutional neural networks (CNNs) for identifying comparatively rare giant radio galaxies from large volumes of survey data, such as those expected for new generation radio telescopes like the SKA and its precursors.
