The MeerKAT International GHz Tiered Extragalactic Exploration Survey (MIGHTEE) is one of the large survey projects using the MeerKAT telescope, covering four fields that have a we…
MIGHTEE-HI: deep spectral line observations of the COSMOS field
I. Heywood, A. A. Ponomareva, N. Maddox +16
The MIGHTEE survey utilises the South African MeerKAT radio telescope to observe four extragalactic deep fields, with the aim of advancing our understanding of the formation and ev…
Deep extragalactic HI survey of the COSMOS field with FAST
Hengxing Pan, Matt J. Jarvis, Ming Zhu +9
We present a deep HI survey at L-band conducted with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) over the COSMOS field. This survey is strategically designed t…
On the implausible physical implications of a claimed lensed neutral hydrogen detection at redshift z = 1.3
Roger P. Deane, Tariq Blecher, Danail Obreschkow +1
The Square Kilometre Array mid-frequency array will enable high-redshift detections of neutral hydrogen (HI) emission in galaxies, providing important constraints on the evolution…
Neutral hydrogen lensing simulations in the Hubble Frontier Fields
Tariq Blecher, Roger Deane, Danail Obreschkow +1
Cold gas evolution ties the formation of dark matter halos to the star formation history of the universe. A primary component of cold gas, neutral atomic hydrogen (HI), can be trac…
MeerKAT observations of starburst galaxies and AGNs within the core of XMMXCS J2215.9-1738 at = 1.46
D. Y. Klutse, M. Hilton, I. Heywood +4
We present the first detailed radio study of the galaxy cluster XMMXCS J2215.9-1738 at = 1.46 using MeerKAT -band (1.3 GHz) observations. We combine our radio observation wi…
The Population of the Galactic Center Filaments: Position Angle Distribution Reveal a Degree-scale Collimated Outflow from Sgr A* along the Galactic Plane
F. Yusef-Zadeh, R. G. Arendt, M. Wardle +1
We have examined the distribution of the position angle (PA) of the Galactic center filaments with lengths and as well as their length distribution as a functi…
Search and characterization of remnant radio galaxies in the XMMLSS deep field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +3
The remnant phase of a radio galaxy is characterized by the cessation of AGN activity resulting in the stoppage of jets supplying plasma to radio lobes. In this paper, we present t…
MeerKAT follow-up of enigmatic GLEAM 4-Jy (G4Jy) sources
