XMM-Newton discovery of 2.6 s pulsations in the soft gamma-ray repeater SGR 1627-41

P. Esposito, A. Tiengo, S. Mereghetti +6

After nearly a decade of quiescence, the soft gamma-ray repeater SGR 1627-41 reactivated on 2008 May 28 with a bursting episode followed by a slowly decaying enhancement of its per…

Physical properties of galaxies and their evolution in the VIMOS VLT Deep Survey. I. The evolution of the mass-metallicity relation up to z~0.9

F. Lamareille, J. Brinchmann, T. Contini +43

We derive the mass-metallicity relation of star-forming galaxies up to , using data from the VIMOS VLT Deep Survey. Automatic measurement of emission-line fluxes and equi…

Simbol-X: A Formation Flight Mission with an Unprecedented Imaging Capability in the 0.5-80 Kev Energy Band

Gianpiero Tagliaferri, Philippe Ferrando, Jean-Michel Le Duigou +8

The discovery of X-ray emission from cosmic sources in the 1960s has opened a new powerful observing window on the Universe. In fact, the exploration of the X-ray sky during the 70…

A Universal Central Engine Hypothesis for Short and Long GRBs

David Eichler, Dafne Guetta, Hadar Manis

It is noted that X-ray tails (XRTs) of short, hard -ray bursts (SHBs) are similar to X-ray flashes (XRFs). We suggest a universal central engine hypothesis, as a way of accounti…

XMM-Newton View of the Multi-Phase Warm Absorber in Seyfert 1 Galaxy NGC985

Yair Krongold, Elena Jimenez-Bailon, Maria Santos-Lleo +6

We present an analysis of an XMM-Newton observation of the Seyfert 1 Galaxy NGC 985. The EPIC spectra present strong residuals to a single power-law model, indicating the presence…

Cosmic Parallax: possibility of detecting anisotropic expansion of the universe by very accurate astrometry measurements

Claudia Quercellini, Miguel Quartin, Luca Amendola

Refined astrometry measurements allow us to detect large-scale deviations from isotropy through real-time observations of changes in the angular separation between sources at cosmi…
