Infrared Synchrotron Emission in the Soft State of GX 339-4 and the Mid-Infrared/X-ray Luminosity Plane of Black Hole X-ray Binaries

P. Gandhi, D. M. Russell, M. C. Baglio +33

Progress in understanding the growth of accreting black holes remains hampered by a lack of sensitive coordinated multiwavelength observations. In particular, the mid-infrared (MIR…

The Mid-infrared Emitting Jet in the Black Hole V404 Cygni in Quiescence

E. S. Borowski, R. I. Hynes, Q. Hunt +13

Observations of some quiescent black hole X-ray binaries have revealed an excess of mid-infrared (MIR) emission above that expected from their donor stars. In one system, V404 Cygn…

Millinovae: A New Class of Transient Supersoft X-ray Sources without a Classical Nova Eruption

Przemek Mróz, Krzysztof Król, Hélène Szegedi +18

Some accreting binary systems containing a white dwarf (such as classical novae or persistent supersoft sources) are seen to emit low-energy X-rays with temperatures of ~10^6 K and…

Correlated X-ray and Optical Variability in V404 Cyg in Quiescence

R. I. Hynes, P. A. Charles, M. R. Garcia +11

We report simultaneous X-ray and optical observations of V404 Cyg in quiescence. The X-ray flux varied dramatically by a factor of >20 during a 60ks observation. X-ray variations w…

Long-term X-ray variability and state transition of GX 339-4

A. K. H. Kong, P. A. Charles, E. Kuulkers +1

With extensive monitoring data spanning over 30 years from Vela 5B, Ariel 5, Ginga, Compton Gamma Ray Observatory, Rossi X-ray Timing Explorer and BeppoSAX, we find evidence for lo…

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

T. Shahbaz, P. Groot, S. N. Phillips +3

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 state (R~15.05). We…
