SAX J1711.6-3808 is an X-ray transient in the Galactic bulge that was active from January through May of 2001 and whose maximum 1-200 keV luminosity was measured to be 5x 10-9 erg cm-2 s-1 which is less than ~ 25% of the Eddington limit, if placed at a distance equal to that of the galactic center. We study the X-ray data that were taken of this

The neutron star low-mass X-ray binary and long thermonuclear burst source XTE J1701-407 (ATel #1618) has been active ever since its discovery in 2008 June (ATel #1569), displaying a typical 2-10 keV luminosity of ~5E36 erg/s (assuming a distance D=5.0 kpc; ATel #2814). However, routine monitoring of the Galactic bulge with the PCA aboard RXTE

The telescope structure including control system and the complete retractable dome of the new 1.5 m solar telescope GREGOR were assembled during 2004 at Izana on Tenerife, Spain. The GREGOR telescope is build by a consortium of the Kiepenheuer Institut fuer Sonnenphysik, the Astrophysikalische Institut Potsdam, the Institut fuer Astrophysik

We present subarcsecond resolution mid-infrared (MIR) images obtained with 8-10 m-class ground-based telescopes of a complete volume-limited (DL

We present fully sampled high angular resolution two-dimensional kinematics in the Hα spectral line, optical and near-infrared imaging, as well as 21 cm atomic hydrogen data of the spiral galaxy NGC 278. This is a small non-barred galaxy, which has a bright star forming inner region of about 2 kpc in diameter, reminiscent of nuclear rings seen

We present our recent spectrophotometric results of the infrared luminous Seyfert 2 galaxy NGC 7679. We find compelling evidence for the presence of a recent nuclear starburst, revealed by the observations of a) the spectral features of high order Balmer absorption lines, b) the weak equivalent widths for CaIIK lambda 3933, CN lambda 4200, G-band
