Optical spectroscopy of the quiescent counterpart to EXO 0748-676: a Black Widow scenario?
E. M. Ratti, D. T. H. Steeghs, P. G. Jonker +3
We present phase-resolved optical spectroscopy of the counterpart to the neutron star low mass X-ray binary EXO 0748-676, almost one year after it turned into quiescence. The spect…
Multiwavelength campaign on Mrk 509 VII. Relative abundances of the warm absorber
K. C. Steenbrugge, J. S. Kaastra, R. G. Detmers +14
Context. The study of abundances in the nucleus of active galaxies allows us to investigate the evolution of abundance by comparing local and higher redshift galaxies. However, the…
Multiwavelength campaign on Mrk 509. III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
R. G. Detmers, J. S. Kaastra, K. C. Steenbrugge +13
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized…
Multiwavelength campaign on Mrk 509. I. Variability and spectral energy distribution
J. S. Kaastra, P. -O. Petrucci, M. Cappi +23
(Abridged) Active galactic nuclei show a wealth of interesting physical processes, some of which are poorly understood. We want to address a number of open questions, including the…
An accurate position for the black hole candidate XTE J1752-223: re-interpretation of the VLBI data
J. C. A. Miller-Jones, P. G. Jonker, E. M. Ratti +4
Using high-precision astrometric optical observations from the Walter Baade Magellan Telescope in conjunction with high-resolution very long baseline interferometric (VLBI) radio i…
The Galactic Bulge Survey: outline and X-ray observations
P. G. Jonker, C. G. Bassa, G. Nelemans +22
We introduce the Galactic Bulge Survey (GBS) and we provide the Chandra source list for the region that has been observed to date. Among the goals of the GBS are constraining the n…
