Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
The Wide Field Monitor onboard the eXTP mission
M. Hernanz, S. Brandt, M. Feroci +37
The eXTP (enhanced X-ray Timing and Polarimetry) mission is a major project of the Chinese Academy of Sciences (CAS) and China National Space Administration (CNSA) currently perfor…
Synthetic NLTE accretion disc spectra for the dwarf nova SS Cyg during an outburst cycle
M. Kromer, T. Nagel, K. Werner
Dwarf nova outbursts result from enhanced mass transport through the accretion disc of a cataclysmic variable system. We assess the question of whether these outbursts are caused b…
Observational constraints on the evolutionary connection between PG 1159 stars and DO white dwarfs
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
The Sloan Digital Sky Survey has provided spectra of a large number of new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects significantly i…
Spectral analyses of 16 DAO white dwarfs from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, T. Rauch +1
We present a spectral analysis of 16 DAO white dwarfs from the Sloan Digital Sky Survey Data Release 4. With our NLTE H+He model grid, we derived photospheric parameters for these…
XMM-Newton observations of the microquasars GRO J1655-40 and GRS 1915+105
Gloria Sala, Jochen Greiner, Frank Haberl +4
We present results of a sequence of XMM-Newton observations of the two microquasars GRO J1655-40 and GRS 1915+105. The observations were preformed using the EPIC-pn camera in the B…
