Observations of the black hole X-ray binary V404 Cyg with the very long baseline interferometer HSA (the High Sensitivity Array) have detected the source at a frequency of 8.4 GHz, providing a source...

The design and performance of the ZEUS Micro Vertex detector (2007)

Brock, I., Goers, S., Kappes, A., Katz, U. F., Hilger, E., Rautenberg, J., ...

In order to extend the tracking acceptance, to improve the primary and secondary vertex reconstruction and thus enhancing the tagging capabilities for short lived particles, the ZEUS experiment at...

The spectral energy distribution of quiescent black hole X-ray binaries: new constraints from Spitzer (2007)

Gallo, E., Migliari, S., Markoff, S., Tomsick, J., Bailyn, C., Berta, S., ...

(Abridged) Among the various issues that remain open in the field of accretion onto black hole X-ray binaries (BHBs) is the way the gas accretes at very low Eddington ratios, in the so-called...

The Spectrum of the Black Hole X-ray Nova V404 Cygni in Quiescence as Measured by XMM-Newton (2007)

Bradley, C. K., Hynes, R. I., Kong, A. K. H., Haswell, C. A., Casares, J., Gallo, E.

We present XMM observations of the black hole X-ray nova V404 Cygni in quiescence. Its quiescent spectrum can be best fitted by a simple power-law with slope 2. The spectra are consistent with that...

Radio and X-ray observations during the outburst decay of the Black Hole Candidate XTE J1908+094 (2007)

Jonker, P. G., Gallo, E., Dhawan, V., Rupen, M., Fender, R. P., Dubus, G.

Obtaining simultaneous radio and X-ray data during the outburst decay of soft X-ray transients is a potentially important tool to study the disc - jet connection. Here we report results of the...

Photoproduction of events with rapidity gaps between jets at HERA (2007)

Chekanov, S., Derrick, M., Magill, S., Miglioranzi, S., Musgrave, B., Nicholass, D., ...

The photoproduction of dijet events, where the two jets with the highest transverse energy are separated by a large gap in pseudorapidity, have been studied with the ZEUS detector using an integrated...

The jet-powered optical nebula of Cygnus X-1 (2007)

Russell, D. M., Fender, R. P., Gallo, E., Kaiser, C. R.

We present H-alpha and [O III] (5007 Angstroms) images of the nebula powered by the jet of the black hole candidate and microquasar Cygnus X-1, observed with the 2.5m Isaac Newton Telescope (INT)....

The Spectrum of the Black Hole X-Ray Nova V404 Cygni in Quiescence as Measured by XMM-Newton (2007)

Bradley, Charles K., Hynes, Robert I., Kong, Albert K. H., Haswell, C. A., Casares, J., Gallo, E.

We present XMM-Newton observations of the black hole X-ray nova V404 Cyg in quiescence. Its quiescent spectrum can be best fitted by a simple power law with slope Γ~2. The spectra are consistent...

Gallo, E., Fender, R., Miller-Jones, J., Merloni, A., Jonker, P., Heinz, S., ...

Deep observations with the Very Large Array of A0620-00, performed in 2005 August, resulted in the first detection of radio emission from a black hole binary at X-ray luminosities as low as 10^{-8.5}...
