Mrk 273 and Mrk 231 are ultra-luminous IR galaxies which show signs of merger activity. Their radio continuum, HI and OH maser emission has been imaged on...
Circumnuclear Regions and their Barred Host Galaxies
In this paper we present first results from an observational study of the connection between the global parameters of barred galaxies and the appearance of...
Circumnuclear regions of active and non-active barred galaxies
New near-infrared (NIR) observations of galaxies with circumnuclear starbursts and of Seyfert galaxies have shown both the importance of high-resolution imaging...
Circumnuclear ring of the starburst galaxy NGC 253. An Infrared view
NGC 253 is a nearby spiral galaxy with an active starburst nucleus. Its proximity allows observation with good spatial resolution with state of the art mid and...
Near-infrared (JHK) images of the nucleus of the barred spiral galaxy M100 (NGC 4321) have been obtained using a high-bandwidth tip-tilt secondary and fast...
Circumnuclear Star-Forming Regions in Barred Galaxies
We present high-resolution Hα velocity fields and rotation curves of the circumnuclear star-forming regions of five barred galaxies. Two of the five objects...
I discuss new observations of circumnuclear regions in barred galaxies, both of their kinematics and their near-infrared (NIR) morphology. New kinematic...
