A Bcool magnetic snapshot survey of solar-type stars
S. C. Marsden, P. Petit, S. V. Jeffers +20
Stellar magnetic field measurements obtained from spectropolarimetry offer key data for activity and dynamo studies, and we present the results of a major high-resolution spectropo…
A statistical investigation of the radio emission of clusters : role of AGNs
J. Lanoux, E. Pointecouteau, M. Giard
Radio emission in the direction of galaxy clusters is due to the individual emission of AGNs, and to the diffuse non-thermal emission of the intracluster medium (ICM). The populati…
Exploring the magnetic topologies of cool stars
J. Morin, J. -F. Donati, P. Petit +19
Magnetic fields of cool stars can be directly investigated through the study of the Zeeman effect on photospheric spectral lines using several approaches. With spectroscopic measur…
Statistical investigation of the non-thermal emission of galaxy clusters
Joseph Lanoux, Etienne Pointecouteau, Martin Giard +1
A diffuse non-thermal component has now been observed in massive merging clusters. To better characterise this component, and to extend analyses done for massive clusters down to a…
The rapid rotation and complex magnetic field geometry of Vega
P. Petit, F. Lignières, G. A. Wade +9
The recent discovery of a weak surface magnetic field on the normal intermediate-mass star Vega raises the question of the origin of this magnetism in a class of stars that was not…
A polarity reversal in the large-scale magnetic field of the rapidly rotating Sun HD 190771
P. Petit, B. Dintrans, A. Morgenthaler +5
Aims. We investigate the long-term evolution of the large-scale photospheric magnetic field geometry of the solar-type star HD 190771. With fundamental parameters very close to tho…
Simulating the impact of dust cooling on the statistical properties of the intracluster medium
E. Pointecouteau, A. Da Silva, A. Catalano +4
From the first stages of star and galaxy formation, non-gravitational processes such as ram pressure stripping, SNs, galactic winds, AGNs, galaxy-galaxy mergers, etc... lead to the…
The impact of dust on the scaling properties of galaxy clusters
Antonio C. da Silva, Andrea Catalano, Ludovic Montier +3
We investigate the effect of dust on the scaling properties of galaxy clusters based on hydrodynamic N-body simulations of structure formation. We have simulated five dust models p…
