BeppoSAX observation of PSR B1937+21

L. Nicastro, G. Cusumano, O. Loehmer +5

We present the results of a BeppoSAX observation of the fastest rotating pulsar known: PSR B1937+21. The ~200 ks observation (78.5 ks MECS/34 ks LECS on-source time) allowed us to…

The phase of the radio and X-ray pulses of PSR B1937+21

G. Cusumano, W. Hermsen, M. Kramer +6

We present timing and spectral results of PSR B1937+21, the fastest known millisecond pulsar (P about 1.56 ms), observed with RXTE. The pulse profile, detected up to 20 keV, shows…

INTEGRAL timing and localization performance

R. Walter, P. Favre, P. Dubath +10

In this letter we report on the accuracy of the attitude, misalignment, orbit and time correlation which are used to perform scientific analyses of the INTEGRAL data. The boresight…

Absolute timing with IBIS, SPI and JEM-X aboard INTEGRAL

L. Kuiper, W. Hermsen, R. Walter +1

We have verified the absolute timing capabilities of the high-energy instruments aboard INTEGRAL, i.e. the imager IBIS, the spectrometer SPI and the X-ray monitor JEM-X. Calibratio…

Chandra and RXTE studies of the X-ray/gamma-ray millisecond pulsar PSR J0218+4232

L. Kuiper, W. Hermsen, B. Stappers

We report on high-resolution spatial and timing observations of the millisecond pulsar PSR J0218+4232 performed with the Chandra X-ray Observatory (CXO) and the Rossi X-ray Timing…

X/gamma-ray measurements of the faint GRB 020321

J. J. M. in 't Zand, L. Kuiper, J. Heise +10

GRB 020321 is a faint GRB that received wide follow-up attention in X-rays (BeppoSAX/NFI, Chandra/ACIS-S, XMM-Newton), radio (ATCA) and optical (ESO, HST). We identify a weak X-ray…

Hard X-ray timing and spectral properties of PSR B0540-69

J. de Plaa, L. Kuiper, W. Hermsen

We report the hard X-ray properties of the young Crab-like LMC pulsar PSR B0540-69, using archival RXTE PCA (2 - 60 keV) and RXTE HEXTE (15 - 250 keV) data. Making use of the very…
