An exploratory study of the hard X-ray variability properties of PG quasars with RXTE
M. Guainazzi, F. Fiore, E. Giallongo +3
We have monitored with the RXTE PCA the variability pattern of the 2-20 keV flux in four PG quasars (QSOs) from the Laor et al. (1994) sample. Six observations of each target at re…

The discovery of the optical/IR counterpart of the 12s transient X-ray pulsar GS 0834-43
G. L. Israel, S. Covino, S. Campana +9
We report the discovery of the optical/infra-red counterpart of the 12.3s transient X-ray pulsar GS0834-43. We re-analysed archival ROSAT PSPC observations of GS0834-43, obtaining…
