Wide-Angle-Tail (WAT) Radio Sources
Galaxies, 2023 We review the properties of Wide-Angle-Tail (WAT) radio sources. The WAT radio sources are powerful, bent radio sources typically associated with the dominant galaxy in a cluster or group.

Discovery of 178 Giant Radio Galaxies in 1059 deg2 of the Rapid ASKAP Continuum Survey at 888 MHz
Galaxies, 2021 We report the results of a visual inspection of images of the Rapid ASKAP Continuum Survey (RACS) in search of extended radio galaxies (ERG) that reach or exceed linear sizes on the order of one Megaparsec. We searched a contiguous area of 1059 deg2 from

Bent It Like FRs: Extended Radio AGN in the COSMOS Field and Their Large-Scale Environment
Galaxies, 2021 A fascinating topic in radio astronomy is how to associate the complexity of observed radio structures with their environment in order to understand their interplay and the reason for the plethora of radio structures found in surveys. In this project, we

Fast radio bursts at the dawn of the 2020s [PDF]
The Astronomy and Astrophysics Review, 2021 Since the discovery of the first fast radio burst (FRB) in 2007, and their confirmation as an abundant extragalactic population in 2013, the study of these sources has expanded at an incredible rate.

Radio properties of Compact Steep Spectrum and GHz‐Peaked Spectrum radio sources [PDF]
, 2015 Compact steep spectrum (CSS) and GHz-peaked spectrum (GPS) radio sources represent a large fraction of the extragalactic objects in flux density-limited samples.

Equipartition Jet Model for the Seyfert 1 Galaxy 3C120 [PDF]
Journal of Astronomy and Space Sciences, 2003 The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...

Star formation properties of sub-mJy radio sources [PDF]
, 2015 We investigate the star formation properties of 800 sources detected in one of the deepest radio surveys at 1.4 GHz. Our sample spans a wide redshift range ( 0.1 4) and about four orders of magnitude in star formation rate (SFR). It includes both star

A BROADBAND POLARIZATION CATALOG OF EXTRAGALACTIC RADIO SOURCES [PDF]
, 2014 An understanding of cosmic magnetism requires converting the polarization properties of extragalactic radio sources into the rest-frame in which the corresponding polarized emission or Faraday rotation is produced.

Classical and Relativistic Evolution of an Extra-Galactic Jet with Back-Reaction
Galaxies, 2018 We consider a turbulent jet that is moving in a Lane⁻Emden ( n = 5 ) medium. The conserved quantity is the energy flux, which allows finding, to first order, an analytical expression for the velocity and an approximate trajectory.

A Comprehensive Observational Study of the FRB 121102 Persistent Radio Source
The Astrophysical Journal, 2023 FRB 121102 is the first fast radio burst to be spatially associated with a persistent radio source (QRS 121102), the nature of which remains unknown. We constrain the physical size of QRS 121102 by measuring its flux-density variability with the VLA from
