Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions at √{s} = 8 {TeV} are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8 {fb}^{-1}. Z bosons are reconstructed through their

Daily measurements of the solar aureole were made at the Vacuum Newton Telescope (/D=40 cm) at the Teide Observatory (Tenerife) for various airmasses. We use these measurements to understand how the aureole is produced and to extrapolate visible measurements to the infrared range (1.6 /μm). This information will be used to correct sunspot

The reliability of infrared (IR) and ultraviolet (UV) emissions to measure star formation rates (SFRs) in galaxies is investigated for a large sample of galaxies observed with the Spectral and Photometric Imaging Receiver (SPIRE) and the Photodetector Array Camera and Spectrometer (PACS) instruments on Herschel as part of the Herschel Multi-Tiered

The determination of fundamental parameters in low-mass X-ray binaries (LMXBs) typically relies on measuring the radial velocity curve of the companion star through optical or near-infrared spectroscopy. It was recently suggested that high resolution X-ray spectroscopy might enable a measurement of the radial velocity curve of the compact object by

We present near-infrared photometry and optical spectroscopy of very low mass stars and brown dwarf candidates in the Pleiades open cluster. The membership status of these objects is assessed using color-magnitude diagrams, lithium and spectral types. Eight objects out of 45 appear to be nonmembers. A search for companions among 34 very low mass
