Spin period evolution of GX 1+4
A. González-Galán, E. Kuulkers, P. Kretschmar +4
We aim both to complement the existing data on the spin history of the peculiar accreting X-ray pulsar GX 1+4 with more past and current data from BeppoSAX, INTEGRAL, and Fermi and…
The MAGIC view of PG 1553+113
E. Prandini, F. Tavecchio, S. Buson +1
We present the results of five years (2005-2009) of MAGIC observations of the BL Lac object PG 1553+113 at very high energies (VHEs). Adding the new data set (2007-2009) to previou…
Pulse period evolution of GX 1+4
A. González-Galán, E. Kuulkers, P. Kretschmar +4
We report on the long-term evolution of the spin period of the symbiotic X-ray pulsar GX 1+4 and a possible interpretation within a model of quasi-spherical accretion. New period m…
