The enigmatic soft X-ray NLS1 RX J0134.2-4258
D. Grupe, K. M. Leighly, H. -C. Thomas +1
We report the discovery and analysis of the follow-up ROSAT pointed observation, an ASCA observation and optical and radio observations of the enigmatic Narrow-Line Seyfert 1 galax…
The enigmatic Soft X-ray AGN RX J0134.2--4258
D. Grupe, K. M. Leighly, H. -C. Thomas +1
We report the discovery and analysis of the follow-up ROSAT pointed observation, an ASCA observation and optical and radio observations of the enigmatic soft X-ray AGN RX J0134.2-4…
RX J1313.2-3259, a long-period Polar discovered with ROSAT
H. -C. Thomas, K. Beuermann, V. Burwitz +2
We report observations of a new AM Herculis binary identified as the optical counterpart of the X-ray source RX J1313.2-3259, detected during the ROSAT All-Sky Survey (RASS). It ha…
RXJ1313.2-3259, a missing link in CV evolution?
B. T. Gaensicke, K. Beuermann, D. de Martino +1
We present low-state IUE spectroscopy of the ROSAT-discovered polar RXJ1313.2-3259. The SWP spectrum displays a broad Lyman alpha absorption profile, which can be fitted with a two…
RX J0501.7-0359: a new ROSAT discovered eclipsing polar in the period gap
Vadim Burwitz, Klaus Reinsch, Klaus Beuermann +1
RXJ 0501.7-0359 is a new V ~ 17 mag eclipsing polar discovered during the ROSAT all-sky survey (RASS). Extensive follow-up observations at X-ray (pointed ROSAT PSPC and HRI observa…
New bright soft X-ray selected ROSAT AGN: I. Infrared-to-X-ray spectral energy distributions
D. Grupe, K. Beuermann, H. -C. Thomas +2
We present results of an infrared-to-X-ray study of 76 bright soft X-ray selected Seyfert galaxies discovered in the ROSAT All-Sky Survey. These objects are characterized by steep…
