The curious activity in the nucleus of NGC 4151: jet interaction causing variability?
D. R. A. Williams, R. D. Baldi, I. M. McHardy +14
A key characteristic of many active galactic nuclei (AGN) is their variability, but its origin is poorly understood, especially in the radio domain. Williams et al. (2017) reported…
LeMMINGs. I. The eMERLIN legacy survey of nearby galaxies. 1.5-GHz parsec-scale radio structures and cores
R. D. Baldi, D. R. A. Williams, I. M. McHardy +29
We present the first data release of high-resolution ( arcsec) 1.5-GHz radio images of 103 nearby galaxies from the Palomar sample, observed with the eMERLIN array, as par…
Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
V. Heesen, D. A. Rafferty, A. Horneffer +16
Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role, they can be best traced with low-frequency radio continuum observations,…
A Radio Continuum Study of Dwarf Galaxies: 6 cm imaging of Little Things
Luke Hindson, Ged Kitchener, Elias Brinks +6
In this paper we examine to what extent the radio continuum can be used as an extinction free probe of star formation in dwarf galaxies. To that aim we observe nearby dwarf ga…
A Spatially Resolved Radio Spectral Index Study of the Dwarf Irregular Galaxy NGC\,1569
Jonathan Westcott, Elias Brinks, Luke Hindson +2
We study the resolved radio-continuum spectral energy distribution of the dwarf irregular galaxy, NGC 1569, on a beam-by-beam basis to isolate and study its spatially resolved radi…
Radio jets in NGC 4151: where eMERLIN meets HST
D. R. A. Williams, I. M. McHardy, R. D. Baldi +11
We present high-sensitivity eMERLIN radio images of the Seyfert galaxy NGC 4151 at 1.5 GHz. We compare the new eMERLIN images to those from archival MERLIN observations in 1993 to…
