The jet of Markarian 501 from millions of Schwarzschild radii down to a few hundreds
M. Giroletti, G. Giovannini, W. D. Cotton +4
Aims: The TeV BL Lac object Markarian 501 is a complex, core dominated radio source, with a one sided, twisting jet on parsec scales. In the present work, we attempt to extend our…
Chandra unveils a binary Active Galactic Nucleus in Mrk463
Stefano Bianchi, Marco Chiaberge, Enrico Piconcelli +2
We analyse Chandra, XMM-Newton and HST data of the double-nucleus Ultraluminous Infrared Galaxy (ULIRG), Mrk463. The Chandra detection of two luminous ($\mathrm{L}_\mathrm{2-10 keV…
HST NIR Snapshot Survey of 3CR Radio Source Counterparts II: An Atlas and Inventory of the Host Galaxies, Mergers and Companions
David J. E. Floyd, David Axon, Stefi Baum +10
We present the second part of an H-band (1.6 microns) atlas of z<0.3 3CR radio galaxies, using the Hubble Space Telescope Near Infrared Camera and Multi-Object Spectrometer (HST NI…
On the nature of optical nuclei in FR I radio-galaxies from ACS/HST imaging polarimetry
Alessandro Capetti, David J. Axon, Marco Chiaberge +4
We obtained optical imaging polarimetry with the ACS/HRC aboard the HST of the 9 closest radio-galaxies in the 3C catalogue with an FR I morphology. The nuclear sources seen in dir…
Isophotal Structure and Dust Distribution in Radio-Loud Elliptical Galaxies
Grant R. Tremblay, Marco Chiaberge, Carlos J. Donzelli +4
We investigate isophotal properties and dust morphology in the nuclear regions of 84 radio galaxies, imaged in the optical and near-infrared as part of Hubble Space Telescope snaps…
Where to look for radiatively inefficient accretion flows (and find them)
Marco Chiaberge
We have studied the nuclear emission detected in high-resolution radio and optical data of carefully selected samples of low luminosity AGN (LLAGN) in the local universe. When the…
