X-ray Radiation from the Millisecond Pulsar J0437-4715
V. E. Zavlin, G. G. Pavlov, D. Sanwal +4
We report on spectral and timing observations of the nearest millisecond pulsar J0437-4715 with Chandra. The pulsar spectrum, detected up to 7 keV, cannot be described by a simple…
The Chandra LETGS high resolution X-ray spectrum of the isolated neutron star RX J1856.5-3754
V. Burwitz, V. E. Zavlin, R. Neuhaeuser +3
We present the Chandra LETGS X-ray spectrum of the nearby (~60 pc) neutron star RX J1856.5-3754. Detailed spectral analysis of the combined X-ray and optical data rules out the non…
The second ROSAT PSPC survey of M31 and the complete ROSAT PSPC source list
R. Supper, G. Hasinger, W. H. G. Lewin +5
This paper reports the results of the analysis of the second ROSAT PSPC survey of M31 performed in summer 1992. We compare our results with those of the first survey. Within the ~1…
The ROSAT Deep Survey: VI. X-ray sources and Optical identifications of the Ultra Deep Survey
I. Lehmann, G. Hasinger, M. Schmidt +10
We describe in this paper the ROSAT Ultra Deep Survey (UDS), an extension of the ROSAT Deep Survey (RDS) in the Lockman Hole. The UDS reaches a flux level of 1.2 x 10E-15 erg/cm2/s…
