Radio imaging of gravitationally lensed radio-quiet quasars
Neal Jackson, Shruti Badole, Thomas Dugdale +4
We present 6-GHz Very Large Array radio images of 70 gravitational lens systems at 300-mas resolution, in which the source is an optically-selected quasar, and nearly all of which…
The Tiered Radio Extragalactic Continuum (T-RECS) simulation II: HI emission and continuum-HI cross-correlation
Anna Bonaldi, Philippa Hartley, Tommaso Ronconi +2
In this paper we extend the Tiered Radio Extragalactic Continuum Simulation (T-RECS) to include HI emission. The HI T-RECS model is based on the most recent HI mass function estima…
Mildly Relativistic Motion in the Radio Quiet Quasar PG 1351+640
Ailing Wang, Tao An, Shaoguang Guo +8
Measuring the proper motion of the emission component in radio-quiet quasars (RQQs) could help to distinguish between the origins of the radio emission and to understand whether th…
Using strong lensing to understand the microJy radio emission in two radio quiet quasars at redshift 1.7
P. Hartley, N. Jackson, S. Badole +3
The radio quasar luminosity function exhibits an upturn around W Hz that is well-modelled by a star-forming host galaxy population. This distribution…
PS J1721+8842: A gravitationally lensed dual AGN system at redshift 2.37 with two radio components
C. S. Mangat, J. P. McKean, R. Brilenkov +4
Dual-Active Galactic Nuclei (AGN) are a natural consequence of the hierarchical structure formation scenario, and can provide an important test of various models for black hole gro…
High-resolution imaging with the International LOFAR Telescope: Observations of the gravitational lenses MG 0751+2716 and CLASS B1600+434
Shruti Badole, Deepika Venkattu, Neal Jackson +7
We present Low-Frequency Array (LOFAR) telescope observations of the radio-loud gravitational lens systems MG 0751+2716 and CLASS B1600+434. These observations produce images at 30…
Gravitational lensing in LoTSS DR2 -- Extremely faint 144-MHz radio emission from two highly magnified quasars
J. P. McKean, R. Luichies, A. Drabent +8
We report extremely faint 144 MHz radio emission from two gravitationally lensed quasars, SDSS J1004+4112 (z = 1.730) and SDSS J2222+2745 (z = 2.803), using the LOFAR Two Metre Sky…
VLA and ALMA observations of the lensed radio-quiet quasar SDSS J0924+0219: a molecular structure in a 3 microJy radio source
S. Badole, N. Jackson, P. Hartley +3
We present Karl G. Jansky Very Large Array (VLA) and Atacama Large Millimetre Array (ALMA) observations of SDSS J0924+0219, a z = 1.524 radio-quiet lensed quasar with an intrinsic…
Strong lensing reveals jets in a sub-microJy radio quiet quasar
P. Hartley, N. Jackson, D. Sluse +2
We present e-MERLIN and EVN observations which reveal unambiguous jet activity within radio quiet quasar HS~0810+2554. With an intrinsic flux density of 880~nJy, this is the fainte…
The Strong Gravitational Lens Finding Challenge
R. Benton Metcalf, M. Meneghetti, Camille Avestruz +33
Large scale imaging surveys will increase the number of galaxy-scale strong lensing candidates by maybe three orders of magnitudes beyond the number known today. Finding these rare…
