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…

Hubble Space Telescope Near-Infrared Snapshot Survey of 3CR radio source counterparts at low redshift

Juan P. Madrid, Marco Chiaberge, David Floyd +9

We present newly acquired images of the near-infrared counterpart of 3CR radio sources. All the sources were selected to have a redshift of less than 0.3 to allow us to obtain the…

An optical-IR jet in 3C133

David J. E. Floyd, Robert Laing, Marco Chiaberge +10

We report the discovery of a new optical-IR synchrotron jet in the radio galaxy 3C133 from our HST/NICMOS snapshot survey. The jet and eastern hotspot are well resolved, and visibl…
