The changing accretion states of the intermediate polar MU Camelopardalis
A. Staude, A. D. Schwope, R. Schwarz +3
We study the timing and spectral properties of the intermediate polar MU Camelopardalis (1RXS J062518.2+733433) to determine the accretion modes and the accretion geometry from mul…
The serendipituous discovery of a short-period eclipsing polar in 2XMMp
J. Vogel, K. Byckling, A. Schwope +3
We report the serendipituous discovery of the new eclipsing polar 2XMMp J131223.4+173659. Its striking X-ray light curve attracted immediate interest when we were visually inspecti…
The XMM large scale structure survey: optical vs. X-ray classifications of active galactic nuclei and the unified scheme
O. Garcet, P. Gandhi, E. Gosset +25
Our goal is to characterize AGN populations by comparing their X-ray and optical classifications. We present a sample of 99 spectroscopically identified X-ray point sources in the…
Strange magnification pattern in the large separation lens SDSS J1004+4112 from optical to X-rays
G. Lamer, A. Schwope, L. Wisotzki +1
We present simultaneous XMM-Newton UV and X-ray observations of the quadruply lensed quasar SDSS J1004+4112 (RBS 825). Simultaneously with the XMM-Newton observations we also perfo…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. IV. A study of six new hard X-ray sources
N. Masetti, L. Bassani, A. Bazzano +9
We present further results from our ongoing optical spectrophotometric campaign at the Astronomical Observatory of Bologna in Loiano (Italy) on unidentified hard X-ray sources dete…
X-ray spectra of XMM-Newton serendipitous medium flux sources
S. Mateos, X. Barcons, F. J. Carrera +7
We report on the results of a detailed analysis of the X-ray spectral properties of a large sample of sources detected serendipitously with the XMM-Newton observatory in 25 selecte…
The proper motion of the isolated neutron star RX J1605.3+3249
C. Motch, K. Sekiguchi, F. Haberl +3
We obtained deep optical imaging of the thermally emitting X-ray bright and radio-quiet isolated neutron star RX J1605.3+3249 with the Subaru telescope in 1999 and 2003. Together w…
A serendipitous survey for galaxy clusters by the XMM-Newton Survey Science Center
A. D. Schwope, G. Lamer, D. Burke +5
We describe the initial results of a programme to detect and identify extended X-ray sources found serendipitously in XMM-Newton observations. We have analysed 186 EPIC-PN images a…
The XMM-Newton Serendipitous Survey. II. First results from the AXIS high galactic latitude medium sensitivity survey
X. Barcons, F. J. Carrera, M. G. Watson +25
We present the first results on the identifications of a medium sensitivity survey (X-ray flux limit 2E-14 erg/cm2/s in the 0.5-4.5 keV band) at high galactic latitude (|b|>20 deg)…
The ROSAT Bright Survey: II. Catalogue of all high-galactic latitude RASS sources with PSPC countrate CR > 0.2 s-1
A. D. Schwope, G. Hasinger, I. Lehmann +7
We present a summary of an identification program of the more than 2000 X-ray sources detected during the ROSAT All-Sky Survey (Voges et al. 1999) at high galactic latitude, |b| >…
The ROSAT BRIGHT survey: I. Identification of an AGN sample with hard ROSAT X-ray spectra
J. -U. Fischer, G. Hasinger, A. D. Schwope +5
The ROSAT Bright Survey (RBS) aims to completely optically identify the more than 2000 brightest sources detected in the ROSAT all-sky survey at galactic latitudes |b| > 30 degr (e…
