PublicaciónH1517+656: The Birth of a BL Lacertae Object?
H1517+656 is an unusual source, even for a BL Lac object. It is one of the most luminous BL Lac objects known, with extreme emission properties at radio...

PublicaciónInfrared photometry of Nova MUSCAE 1991 (=GS 1124-68)
We have obtained an H-band infrared light curve of the low-mass X-ray binary transient Nova Muscae 1991. We model the light curve as being due to the tidal...

PublicaciónInfrared spectroscopy of V404 Cygni: limits on the accretion disc contamination
We have obtained for the first time 2.10-2.45 μm infrared spectra of the soft-X-ray transient V404 Cygni. We determine a 95 per cent confidence upper limit to...

PublicaciónInvestigating accretion disk - radio jet coupling across the stellar mass scale
Relationships between the X-ray and radio behavior of black hole X-ray binaries during outbursts have established a fundamental coupling between the accretion...

PublicaciónJet spectral breaks in black hole X-ray binaries
In X-ray binaries, compact jets are known to commonly radiate at radio to infrared frequencies, whereas at optical to γ-ray energies, the contribution of the...

PublicaciónLarge-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding...

PublicaciónLight-curve models for a pulsar orbiting a Kerr black hole
We have studied the signal received by a distant observer from a pulsar orbiting a stellar black hole. The binary system has a non-eccentric orbit and the most...
