SuperMIGHTEE : Spectral Ages of Remnant Radio Galaxy Candidates in the XMM-LSS Field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +8
Remnant radio galaxies, whose lobes are no longer replenished by jets from the active galactic nucleus (AGN), offer key constraints on AGN duty cycles and the timescales of radio j…
MIGHTEE: Discovery of a triple-double radio galaxy
Tombo F. Rarivoarinoro, Zara Randriamanakoto, Russ Taylor +8
Triple-double radio galaxies (TDRGs) are amongst the rarest subpopulations of radio galaxies (RGs). They are characterised by three pairs of radio lobes, where each pair of lobes r…
Machine Learning Approaches for Classifying Star-Forming Galaxies and Active Galactic Nuclei from MIGHTEE-Detected Radio Sources in the COSMOS Field
Walter Silima, Fangxia An, Mattia Vaccari +2
Radio synchrotron emission originates from both massive star formation and black hole accretion, two processes that drive galaxy evolution. Efficient classification of sources domi…
SALT spectroscopic follow-up of the G4Jy Sample
Sarah V. White, Kshitij Thorat, Moses Mogotsi +9
The GLEAM 4-Jy (G4Jy) Sample is a thorough compilation of the 'brightest' radio sources in the southern sky (Declination < 30 deg), as measured at 151 MHz (S > 4.0 Jy) with the Mur…
MIGHTEE: multi-wavelength counterparts in the COSMOS field
I. H. Whittam, M. Prescott, C. L. Hale +26
In this paper we combine the Early Science radio continuum data from the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Survey, with optical and near-infrared…
The [OIII] profiles of far-infrared active and non-active optically-selected green valley galaxies
Antoine Mahoro, Petri Väisänen, Mirjana Pović +8
We present a study of the line profile in a sub-sample of 8 active galactic nuclei (AGN) and 6 non-AGN in the optically-selected green valley at $\rm{z\,<\,0.5…
MIGHTEE: the nature of the radio-loud AGN population
I. H. Whittam, M. J. Jarvis, C. L. Hale +24
We study the nature of the faint radio source population detected in the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Early Science data in the COSMOS field…
MIGHTEE: total intensity radio continuum imaging and the COSMOS / XMM-LSS Early Science fields
I. Heywood, M. J. Jarvis, C. L. Hale +23
MIGHTEE is a galaxy evolution survey using simultaneous radio continuum, spectro-polarimetry, and spectral line observations from the South African MeerKAT telescope. When complete…
Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
Fangxia An, M. Vaccari, Ian Smail +17
We study the radio spectral properties of 2,094 star-forming galaxies (SFGs) by combining our early science data from the MeerKAT International GHz Tiered Extragalactic Exploration…
MIGHTEE: Are giant radio galaxies more common than we thought?
J. Delhaize, I. Heywood, M. Prescott +31
We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a…
The infrared-radio correlation of star-forming galaxies is strongly M-dependent but nearly redshift-invariant since z4
I. Delvecchio, E. Daddi, M. T. Sargent +25
Several works in the past decade have used the ratio between total (rest 8-1000m) infrared and radio (rest 1.4~GHz) luminosity in star-forming galaxies (q), often referre…
Effect of the environment on star formation activity and stellar mass for star-forming galaxies in the COSMOS field
S. M. Randriamampandry, M. Vaccari, K. M. Hess
We investigate the relationship between environment and the galaxy main sequence (the relationship between stellar mass and star formation rate) and also the relationship between e…
Star-forming Galaxies in Intermediate Redshift Clusters: Stellar vs. Dynamical Masses of Luminous Compact Blue Galaxies
S. M. Randriamampandry, S. M. Crawford, M. A. Bershady +2
We investigate the stellar masses of the class of star-forming objects known as Luminous Compact Blue Galaxies (LCBGs) by studying a sample of galaxies in the distant cluster MS…
Far-infrared-radio relation in cluster galaxies at intermediate redshift
Solohery M. Randriamampandry
The radio luminosities at 1.4 GHz is tightly correlated with the far-infrared luminosities for various galaxy types (e.g. [16, 6, 2]) over a wide range of redshift (see e.g. [5, 1,…
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters II. Physical Properties of dE Progenitor Candidates
S. M. Crawford, Gregory D. Wirth, M. A. Bershady +1
Luminous Compact Blue Galaxies (LCBGs) are an extreme star-bursting population of galaxies that were far more common at earlier epochs than today. Based on spectroscopic and photom…
