A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
HST Spectroscopy of the Nucleus of M33
Knox S. Long, Philip A. Charles, Guillaume Dubus
We have used Hubble Space Telescope to obtain moderate resolution 1150-5700 Ang. spectroscopy of the nucleus of M33 and a blue star ~1 arcsec NNW of the nucleus in an attempt to fi…
Disc instability models, evaporation and radius variations
Jean-Marie Hameury, Guillaume Dubus, Jean-Pierre Lasota +1
We show that the outcome of disc instability models is strongly influenced by boundary conditions such as the position of the inner and outer disc edges. We discuss other sources o…
Evidence for evolving accretion disk structure in 4U 1957+115
Pasi Hakala, Panu Muhli, Guillaume Dubus
We present results of the first multicolour photometric study of 4U1957+115, one of the optically less studied low mass X-ray binaries (LMXB). Our quasi-simultaneous UBVRI observat…
