Disentangling the radio flux contribution from star formation (SF) and active-galactic-nuclei (AGN) activity is a long-standing problem in extragalactic astronomy, since at frequen…
An Interferometric SETI Observation of Kepler-111 b
Kelvin Wandia, Michael A. Garrett, Jack F. Radcliffe +8
The application of Very Long Baseline Interferometry (VLBI) to the Search for Extraterrestrial Intelligence (SETI) has been limited to date, despite the technique offering many adv…
Intermediate-mass black holes: finding of episodic, large-scale and powerful jet activity in a dwarf galaxy
Jun Yang, Zsolt Paragi, Sándor Frey +10
Dwarf galaxies are characterised by a very low luminosity and low mass. Because of significant accretion and ejection activity of massive black holes, some dwarf galaxies also host…

We present the second data release of high-resolution ( arcsec) 1.5-GHz radio images of 177 nearby galaxies from the Palomar sample, observed with the e-MERLIN array, as p…
The e-MERLIN Galaxy Evolution Survey (e-MERGE): Overview and Survey Description
T. W. B. Muxlow, A. P. Thomson, J. F. Radcliffe +37
We present an overview and description of the eMERLIN Galaxy Evolution survey (eMERGE) Data Release 1 (DR1), a large program of high-resolution 1.5 GHz radio observations of the GO…
VV 655 and NGC 4418: Implications of an interaction for the evolution of a LIRG
Erin Boettcher, John S. Gallagher, Youichi Ohyama +6
VV 655, a dwarf irregular galaxy with HI tidal debris, is a companion to the lenticular luminous infrared galaxy (LIRG) NGC 4418. NGC 4418 stands out among nearby LIRGs due to its…
The hidden heart of the luminous infrared galaxy IC 860 I. A molecular inflow feeding opaque, extreme nuclear activity

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…
