J1615+5452: a remnant radio galaxy in the ELAIS-N1 field
(Oxford University Press, 2020)
We report the discovery of a remnant radio active galactic nucleus (AGN) J1615+5452 in the field of ELAIS-N1. GMRT continuum observations at 150, 325, and 610 MHz combined with archival data from the 1.4 GHz NVSS survey ...
One- and Two-point source statistics from the LOFAR Two-metre sky survey first data release
(ESO, 2020)
Context. The LOFAR Two-metre Sky Survey (LoTSS) will eventually map the complete Northern sky and provide an excellent
opportunity to study the distribution and evolution of the large-scale structure of the Universe.
Aims. ...
Cosmic evolution of star-forming galaxies to z 1.8 in the faint low-frequency radio source population
(Oxford University Press, 2019)
We study the properties of star-forming galaxies selected at 610 MHz with the GMRT in a survey covering ∼1.86 deg2 down to a noise of ∼7.1 μJy beam−1. These were identified by combining multiple classification diagnostics: ...
Non-Gaussianity constraints using future radio continuum surveys and the multitracer technique
(Oxford University Press, 2019)
Tighter constraints on measurements of primordial non-Gaussianity (PNG) will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum – the standard method of measuring the local ...
Deep GMRT 610 MHz observations of the ELAIS N1 field: Catalogue and source counts
(Oxford University Press, 2019)
This is the first of a series of papers based on sensitive 610 MHz observations of the ELAIS N1 field, using the Giant Metrewave Radio Telescope. We describe the observations, processing and source catalogue extraction ...
The relation between the diffuse X-ray luminosity and the radio power of the central AGN in galaxy groups
(Oxford University Press, 2020)
Our understanding of how active galactic nucleus feedback operates in galaxy clusters has improved in recent years owing to large efforts in multiwavelength observations and hydrodynamical simulations. However, it is much ...
A wide-area GMRT 610-MHz survey of ELAIS N1 field
(Oxford University Press, 2020)
In this paper, we present a wide-area 610-MHz survey of the ELAIS N1 field with the GMRT, covering an area of 12.8 deg2 at a resolution of 6 arcsec and with an rms noise of ∼40 μJy beam−1. This is equivalent to ∼20 μJy ...
The faint radio source population at 15.7 GHz – IV. The dominance of core emission in faint radio galaxies
(Oxford University Press, 2020)
We present 15-GHz Karl G. Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7 GHz from the Tenth Cambridge (10C) survey. 67 out of the 95 sources (71 per cent) are unresolved in the ...
The e-MERGE Survey (e-MERLIN Galaxy Evolution Survey): Overview and survey description
(Oxford University Press, 2020)
We present an overview and description of the e-MERGE Survey (e-MERLIN Galaxy Evolution Survey) Data Release 1 (DR1), a large program of high-resolution 1.5-GHz radio observations of the GOODS-N field comprising ∼140 h of ...
The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field
(Oxford University Press, 2021)
We study the cosmic evolution of radio sources out to z ≃ 1.5 using a GMRT 610 MHz survey covering ∼1.86 deg2 of the ELAIS N1 field with a minimum/median rms noise 7.1/19.5 μJy beam−1 and an angular resolution of 6 arcsec. ...
