The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
Nowhere to Hide: Radio-faint AGN in the GOODS-N field. II. Multi-wavelength AGN selection techniques and host galaxy properties
J. F. Radcliffe, P. D. Barthel, A. P. Thomson +3
Obtaining a census of active galactic nuclei (AGN) activity across cosmic time is critical to our understanding of galaxy evolution and formation. Many AGN classification technique…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger
S. Mattila, M. Pérez-Torres, A. Efstathiou +33
Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transien…
The MeerKAT Absorption Line Survey (MALS)
N. Gupta, R. Srianand, W. Baan +41
Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
The radio evolution of supernova SN2008iz in M82
N. Kimani, K. Sendlinger, A. Brunthaler +7
We report on multi-frequency Very Large Array (VLA) and Very Long Baseline Interferometry (VLBI) radio observations for a monitoring campaign of supernova SN2008iz in the nearb…
The Astrophysics of Star Formation Across Cosmic Time at 10 GHz with the Square Kilometre Array
Eric J. Murphy, Mark T. Sargent, Rob J. Beswick +12
In this chapter, we highlight a number of science investigations that are enabled by the inclusion of Band~5 ( GHz) for SKA1-MID science operations, while focusing on the…
Very Long Baseline Interferometry with the SKA
Zsolt Paragi, Leith Godfrey, Cormac Reynolds +79
Adding VLBI capability to the SKA arrays will greatly broaden the science of the SKA, and is feasible within the current specifications. SKA-VLBI can be initially implemented by pr…
Sub-arcsecond high sensitivity measurements of the DG~Tau jet with e-MERLIN
Rachael E. Ainsworth, Tom P. Ray, Anna M. M. Scaife +2
We present very high spatial resolution deep radio continuum observations at 5 GHz (6 cm) made with e-MERLIN of the young stars DG Tau A and B. Assuming it is launched very close (…
Radio Continuum Surveys with Square Kilometre Array Pathfinders
Ray P. Norris, J. Afonso, D. Bacon +48
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation radio telescopes and upgrades are already being built around the world. These include APERTIF (T…
Hanny's Voorwerp: Evidence of AGN activity and a nuclear starburst in the central regions of IC 2497
H. Rampadarath, M. A. Garrett, G. I. G. Józsa +7
We present high- and intermediate resolution radio observations of the central region in the spiral galaxy IC 2497, performed using the European VLBI Network (EVN) at 18 cm, and th…
