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…
The low-mass YSO CB230-A: investigating the protostar and its jet with NIR spectroscopy and Spitzer observations
Fabrizio Massi, Claudio Codella, Jan Brand +2
A jet from the low-mass YSO CB230-A had been discovered in NIR narrow-band images. We aim to investigate the physical properties of the region from where the jet is launched. Our a…
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…
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey
D. J. Pinfield, B. Burningham, M. Tamura +32
We present the discovery of fifteen new T2.5-T7.5 dwarfs (with estimated distances between ~24-93pc, identified in the first three main data releases of the UKIRT Infrared Deep Sky…
Exploring the substellar temperature regime down to ~550K
Ben Burningham, D. J. Pinfield, S. K. Leggett +15
We report the discovery of three very late T dwarfs in the UKIRT Infrared Deep Sky Survey (UKIDSS) Third Data Release: ULAS J101721.40+011817.9 (ULAS1017), ULAS J123828.51+095351.3…
El Roque de Los Muchachos Site Characteristics. III. Analysis of Atmospheric Dust and Aerosol Extinction
G. Lombardi, V. Zitelli, S. Ortolani +2
Canary Islands are normally interested by dominant North-East winds that, in some meteorological conditions, can transport sand at high altitude from the Sahara desert. The dust ma…
