We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) suite of cosmological hydrodynamical simulations to study the formation of stellar spheroids of Milky Way mass disc galaxies. The simulations contain accurate treatments of metal-dependent radiative cooling, star formation, supernova feedback and chemodynamics, and the large

This paper presents the case of CoRoT LRa02_E2_0121, which was initially classified as a Neptune-size transiting-planet candidate on a relatively wide orbit of 36.3 days. Follow-up observations were performed with UVES, Sandiford, SOPHIE, and HARPS. These observations revealed a faint companion in the spectra. To find the true nature of the system

The CoRoT satellite is the first instrument hunting for planets from space. We will review the status of the CoRoT/Exoplanet program. We will then present the CoRoT exoplanetary systems and how they widen the range of exoplanet properties and contribute to our understanding of these objects.

The extraction of resonance parameters from meson photo-reaction data is a challenging effort, that would greatly benefit from the availability of several polarization observables, measured for each reaction channel on both proton and neutron targets. In the aim of obtaining such complete experiments, polarized photon beams and targets have been

The observations (program GO 10861) were taken between 2006 November and 2007 January with the HST/ACS camera (2x4096x2048 pixels, 0.05arcsec/pixel, 3-arcsec interchip gap). (1 data file).

The spectroscopic observations were carried out at VLT/FLAMES between 2003 and 2004, with the exception of one pointing which was re-observed in 2008 May, during the commissioning of the upgraded Grating Instrument for Radiation Analysis with a Fiber-FedEchelle (GIRAFFE) spectrograph CCD.
