The origin of radio emission in broad absorption line quasars: Results from the Lofar Two-metre Sky Survey (Corrigendum)
(EDP Sciences, 2020)
We report an erratum in Morabito et al. (2019, A&A, 622, A15). When calculating radio powers from observed flux densities, the wrong sign convention was used. This resulted in an underestimation of the radio powers by a ...
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. ...
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. ...
The infrared-radio correlation of star-forming galaxies is strongly M∗-dependent but nearly redshift-invariant since z ∼4
(EDP Sciences, 2021)
Over the past decade, several works have used the ratio between total (rest 8-1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (qIR), often referred to as the infrared-radio correlation (IRRC), ...
MIGHTEE: Are giant radio galaxies more common than we thought?
(Oxford University Press, 2021)
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 ∼}1\, deg2 region inside the COSMOS field. ...
