The nuclear architecture of NGC 4151: on the path toward a universal outflow mechanism in light of NGC 1068
D. May, J. E. Steiner, R. B. Menezes +2
We report near-infrared integral field spectroscopic observations of the active galactic nucleus NGC 4151 with archive data from the NIFS-Gemini North Telescope. We have selected b…
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…
Jets, Arcs and Shocks: NGC 5195 at radio wavelengths
H. Rampadarath, R. Soria, R. Urquhart +10
We studied the nearby, interacting galaxy NGC 5195 (M51b) in the radio, optical and X-ray bands. We mapped the extended, low-surface-brightness features of its radio-continuum emis…
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…
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…
