JKCS041: a colour-detected galaxy cluster at z_phot=1.9 with deep potential well as confirmed by X-ray data
S. Andreon, B. Maughan, G. Trinchieri +1
[Abridged] We report the discovery of JKCS041, a massive near-infrared selected cluster of galaxies z=1.9. The cluster was originally discovered using a modified red-sequence metho…
Obscured and powerful AGN and starburst activities at z~3.5
M. Polletta, A. Omont, S. Berta +9
We report the discovery of two sources at z=3.867 and z=3.427 that exhibit powerful starburst and AGN activities. They benefit from data from radio to X rays from the CFHTLS-D1/SWI…
Discovery of Hot Gas in Outflow in NGC3379
G. Trinchieri, S. Pellegrini, G. Fabbiano +10
We report the discovery of a faint (L_x ~ 4 10^37 erg/s, 0.5-2 keV), out-flowing gaseous hot interstellar medium (ISM) in NGC 3379. This represents the lowest X-ray luminosity ever…
XMM-Newton X-ray and Optical Monitor far UV observations of NGC 7070A and ESO 2400100 shell galaxies
G. Trinchieri, R. Rampazzo, C. Chiosi +3
We present XMM-Newton X-ray observations of two shell galaxies, NGC 7070A and ESO 2400100, and far UV observations obtained with the Optical Monitor for these and for an additional…
Detection of a hot intergalactic medium in the spiral-only compact group SCG0018-4854
G. Trinchieri, A. Iovino, E. Pompei +4
AIMS: Compact groups of galaxies are excellent laboratories for studying galaxy interactions and their effects on the evolution of galaxies. In particular, dynamically young system…
Early-type galaxies with neutral hydrogen in the Virgo cluster from the ALFALFA survey
S. di Serego Alighieri, M. Grossi, C. Giovanardi +2
We extend our published work on the neutral hydrogen content of early-type galaxies in the Virgo cluster using the catalogue of detected sources from the ALFALFA survey, by showing…
