The curious activity in the nucleus of NGC 4151 : jet interaction causing variability?
(2020-05-04)
A key characteristic of many active galactic nuclei (AGNs) is their variability, but its origin is poorly understood, especially in the radio domain. Williams et al. (2017) reported a ∼50 per cent increase in peak flux ...
Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
(2018-05-11)
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, which are less affected by spectral ageing. ...
Radio jets in NGC 4151 where eMERLIN meets HST
(2017-12-21)
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 determine the change in jet morphology in ...
