An analysis of electron distributions in galaxy clusters by means of the flux ratio of iron lines FeXXV and XXVI
D. A. Prokhorov, F. Durret, V. A. Dogiel +1
The interpretation of hard X-ray emission from galaxy clusters is still ambiguous and different models proposed can be probed using various observational methods. Here we explore a…
The HARPS search for southern extra-solar planets. XVII. Super-Earth and Neptune-mass planets in multiple planet systems HD47186 and HD181433
F. Bouchy, M. Mayor, C. Lovis +8
This paper reports on the detection of two new multiple planet systems around solar-like stars HD47186 and HD181433. The first system includes a hot Neptune of 22.78 M_Earth at 4.0…
A giant bar induced by a merger event at z=0.4?
Sébastien Peirani, Francois Hammer, Hector Flores +2
(Aims) We present a physical model of the formation of J033239.72-275154.7, a galaxy observed at z=0.41 and characterized by a big young bar of size 6 kpc. The study of this system…
325-MHz observations of the ELAIS-N1 field using the Giant Metrewave Radio Telescope
S. K. Sirothia, M . Dennefeld, D. J. Saikia +3
We present observations of the European Large-Area {\it ISO} Survey-North 1 (ELAIS-N1) at 325 MHz using the Giant Metrewave Radio Telescope (GMRT), with the ultimate objective of i…
Characterization of the HD 17156 planetary system
M. Barbieri, R. Alonso, S. Desidera +11
AIMS : To improve the parameters of the HD 17156 system (peculiar due to the eccentric and long orbital period of its transiting planet) and constrain the presence of stellar compa…
The spatial clustering of X-ray selected AGN in the XMM-COSMOS field
R. Gilli, G. Zamorani, T. Miyaji +70
We study the spatial clustering of 538 X-ray selected AGN in the 2 deg^2 XMM-COSMOS field that are spectroscopically identified to I_{AB}<23 and span the redshift range z=0.2-3.0.…
