    A rapid response to GRB 070411

    We report on early observations of the optical afterglow of GRB 070411 obtained by the Črni Vrh 0.6-m, the ROTSE IIIc 0.45-m, and the Tautenburg 1.34-m Schmidt...

    An X-ray survey of extragalactic radio jets with Chandra

    We are performing a survey of a sample of 17 radio jets with Chandra and HST, with the aim of finding their X-ray and optical counterparts. In this paper, we...

    Bowen Blend Echo-Tomography of Sco X-l and V801 Ara

    We present simultaneous high time resolution (1-10 Hz) X-ray and optical observations of the persistent LMXBs Sco X-l and V801 Ara( = 4 U 1636-536). In the case...

    Chandra/ELAIS mid-infrared sources (Manners+, 2004)

    As part of ELAIS, ISOCAM observations were carried out covering 10.3deg2 at 15um. The observations were carried out in raster mode, with most of the survey area...

    Extinction as a tool to find distances to X-ray sources

    Finding distances in astronomy is notoriously difficult. With accurate optical spectroscopy, both the distance to and extinction (reddening) of normal stars can...

    GRB 070610: Flares from a peculiar Galactic source

    The majority of bright gamma-ray transients that we observe in the sky, are produced by extragalactic gamma-ray bursts (GRBs). However, we know that there are...

    Irradiation of the secondary star in X-ray Nova Scorpii 1994 (=GRO J1655-40)

    We have obtained intermediate resolution optical spectra of the black-hole candidate Nova Sco 1994 in June 1996, when the source was in an X-ray/optical active...

    Luminous X-ray sources Chandra fluxes (Alonso-Herrero+, 2004)

    We investigate the luminous X-ray sources in the Lockman Hole (LH) and the extended Groth strip (EGS) detected at 24{mu}m using the Multiband Imaging Photometer...
