We present detailed simulations of the Warm-Hot Intergalactic Medium (WHIM) with the gratings of Constellation-X. Simulations are based on the extrapolation of the expected number density of OVII WHIM systems from hydrodynamical simulations of the local Universe, up to redshift of z=1 and down to an OVII column density of 1014 cm-2, and assume

We report the detection of the first two microlensing candidates from the Wendelstein Calar Alto Pixellensing Project (WeCAPP). Both are detected with a high signal-to-noise ratio and were filtered out from 4.5 million pixel light curves using a variety of selection criteria. Here we only consider well-sampled events with timescales of 1 day

We present the second paper of a series of publications aiming at obtaining a better understanding regarding the nature of type Ia supernovae (SN Ia) progenitors by studying a large sample of detached F, G and K main-sequence stars in close orbits with white dwarf companions (i.e. WD+FGK binaries). We employ the Large Sky Area Multi-Object Fibre

We report on the x-ray spectrum and lightcurve of the eclipsing Low-Mass X-ray Binary (LMXB) 4U2129+47 as observed with the ROSAT PSPC during its current quiescent state. Contrary to earlier indications with the ROSAT HRI, the eclipse seen during the high state is still present. The eclipse duration, amplitude, and the fraction of residual flux

We present a direct measurement of the mean halo occupation distribution (HOD) of galaxies taken from the eleventh data release (DR11) of the Sloan Digital Sky Survey-III Baryon Oscillation Spectroscopic Survey (BOSS). The HOD of BOSS low-redshift (LOWZ: 0.2 z 0.4) and Constant-Mass (CMASS: 0.43 z 0.7) galaxies is inferred via their association

Aims:X-ray sources at intermediate fluxes (a few × 10-14 erg cm-2 s-1) with a sky density of ~100 deg-2 are responsible for a significant fraction of the cosmic X-ray background at various energies below 10 keV. The aim of this paper is to provide an unbiased and quantitative description of the X-ray source population at these fluxes and in various
