Gemini Spectroscopy of Ultra-Compact Dwarfs in the Fossil Group NGC 1132
Juan P. Madrid, Carlos Donzelli
A spectroscopic follow up of Ultra-Compact Dwarf (UCD) candidates in the fossil group NGC 1132 is undertaken with the Gemini Multi Object Spectrograph (GMOS). These new Gemini spec…
The 2010 very high energy gamma-ray flare & 10 years of multi-wavelength observations of M 87
The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
The Luminosity Profiles of Brightest Cluster Galaxies
C. J. Donzelli, Hernan Muriel, Juan P. Madrid
(Abridged) We have derived detailed R band luminosity profiles and structural parameters for a total of 430 brightest cluster galaxies (BCGs), down to a limiting surface brightness…
Ultra-Compact Dwarfs in the Fossil Group NGC 1132
Juan P. Madrid
Eleven Ultra-Compact Dwarf (UCD) and 39 extended star cluster candidates are found to be associated with the galaxy NGC 1132. This giant elliptical galaxy is the remnant of a fossi…
Ultra-Compact Dwarfs in the Core of the Coma Cluster
Juan P. Madrid, Alister W. Graham, William E. Harris +6
We have discovered both a red and a blue subpopulation of Ultra-Compact Dwarf (UCD) galaxy candidates in the Coma galaxy cluster. We analyzed deep F475W (Sloan g) and F814W (I) Hub…
Hubble Space Telescope Near Infrared Snapshot Survey of 3CR radio source counterparts III: Radio galaxies and quasars in context
David J. E. Floyd, David Axon, Stefi Baum +6
We compare the near-infrared (NIR) H band photometric and morphological properties of low-redshift (z<0.3) 3CR radio galaxies with samples of BL Lac object and quasar host galaxies…
