Cluster Abell 520: a perspective based on member galaxies. A cluster forming at the crossing of three filaments?
M. Girardi, R. Barrena, W. Boschin +1
The connection of cluster mergers with the presence of extended, diffuse radio sources in galaxy clusters is still debated. An interesting case is the rich, merging cluster Abell 5…
Optical analysis of the poor clusters Abell 610, Abell 725, and Abell 796, containing diffuse radio sources
W. Boschin, R. Barrena, M. Girardi +1
We study the dynamical status of the poor, low X-ray luminous galaxy clusters Abell 610, Abell 725, and Abell 796 (at z=0.1, 0.09, and 0.16, respectively), containing diffuse radio…
The dynamical status of the galaxy cluster Abell 115
R. Barrena, W. Boschin, M. Girardi +1
We present the results of a new spectroscopic and photometric survey of the hot, binary X-ray cluster A115 at z=0.193, containing a radio relic. We combine galaxy velocity and posi…
Internal dynamics of the radio halo cluster Abell 773: a multiwavelength analysis
R. Barrena, W. Boschin, M. Girardi +1
We conduct an intensive study of the rich, X-ray luminous galaxy cluster A773 at z=0.22 containing a diffuse radio halo to determine its dynamical status. Our analysis is based on…
Internal dynamics of the massive cluster Abell 697: a multiwavelength analysis
M. Girardi, W. Boschin, R. Barrena
We conduct an intensive study of the rich, X-ray luminous, and hot galaxy cluster Abell 697 (at z=0.282), likely containing a diffuse radio emission, to determine its dynamical sta…
The Narrow Line Region of the Seyfert 2 galaxy Mrk 78. An infrared view
C. Ramos Almeida, A. M. Pérez García, J. A. Acosta-Pulido +3
We report near-infrared spectroscopic data for the Seyfert 2 galaxy Mrk 78, taken with the LIRIS near-infrared camera/spectrometer at the William Herschel Telescope (WHT). The long…
