During the 1996/1997 outburst of the X-ray transient GRO J1655-40 the Wide Field Cameras onboard BeppoSAX observed the system with nearly continuous coverage...
Type I X-ray bursts and burst oscillations in the accreting millisecond X-ray pulsar IGR J17511-3057
We report the discovery of burst oscillations at the spin frequency in ten thermonuclear bursts from the accreting millisecond X-ray pulsar (AMXP) IGR J17511...
Type I X-ray bursts, burst oscillations and kHz quasi-periodic oscillations in the neutron star system IGRJ17191-2821
We present a detailed study of the X-ray energy and power spectral properties of the neutron star transient IGRJ17191-2821. We discovered four instances of...
ULTRACAM observations of the black hole X-ray transient XTE J1118+480 in quiescence
We present high time-resolution multicolour observations of the quiescent soft X-ray transient XTE J1118+480 obtained with ULTRACAM. Superimposed on the double...
UltraCompCAT: A comprehensive catalogue of ultra-compact and short orbital period X-ray binaries
Ultracompact X-ray binaries (UCXBs) are a distinctive but elusive family of low-mass X-ray binaries (LMXBs) characterised by their tight orbits and degenerate...
Unveiling optical signatures of outflows in accreting white dwarfs
Accreting white dwarfs are known to show signatures of wind-type outflows in the ultraviolet. However, at optical wavelengths, wind detections have only been...
Unveiling recurrent jets of the ULX Holmberg II X-1: evidence for a massive stellar-mass black hole?
We report on the discovery of an apparent triple radio structure hidden inside the radio bubble of the ultraluminous X-ray source Holmberg II X-1. The...
V Sge: supersoft source or exotic hot binary? – I. An X-Shooter campaign in the high state
V Sge is a peculiar, highly luminous long-period (12.34 h) binary star that can display a supersoft X-ray emitting component when in the faint phase of its $V...
We present time-resolved optical spectroscopy and photometry of the nova-like cataclysmic variable V348 Puppis. The system displays the same spectroscopic...
