MeerKAT follow-up of enigmatic GLEAM 4-Jy (G4Jy) sources

ABSTRACT We present the results from studying 140 radio sources in GLEAM (GaLactic and Extragalactic All-sky MWA [Murchison Widefield Array]) 4-Jy (G4Jy) Sample. These were followed-up with MeerKAT to assess their morphology enable host-galaxy identification, as existing images of 25 45-arcsec resolution do not provide sufficient information. refer these MeerKAT-2019 subset. The aim is identify host galaxy by visually inspecting overlays comprising data four surveys (at 150, 200, 843/1400, 1300 MHz). Our morphological classification identification relies upon ∼7-arcsec (1300 Through visual inspection overlays, 14 subset have wide-angle tail morphology, 10 are head-tail, 5 X-, S-/Z-shaped morphology. Most remaining typical symmetric lobes. Of sources, we find galaxies for 98 leaving 42 no identified galaxy. still ambiguous even higher MeerKAT.
