PublicationDiscovery of the neutron star nature of SLX 1737-282
SLX 1737-282 is a persistent moderately bright X-ray source 1fdg2 from the Galactic center. X-ray observations with the Wide Field Cameras on BeppoSAX have for...

PublicationDiscovery of variable circular polarization from the remnant of Nova Chamaeleontis 1953 (RR Cha)
We report on the discovery of variable circular polarization from the remnant of Nova Chamaeleontis 1953 (RR Cha). The circular polarization appears to be...

PublicationDisentangling jet and disc emission from the 2005 outburst of XTE J1118+480
The black hole X-ray transient, XTE J1118+480, has now twice been observed in outbursts - 2000 and 2005 - and on both occasions remained in the low/hard X-ray...

PublicationDoppler and modulation tomography of XTEJ1118+480 in quiescence
We present Doppler and modulation tomography of the X-ray nova XTEJ1118+480 with data obtained during quiescence using the 10-m Keck II telescope. The hotspot...
