Timing and spectral study of XB 1254-690 using new RXTE PCA data
accretion, accretion disks — methods: data analysis — stars: neutron— techniques: miscellaneous — X-rays: binaries — X-rays: individual
2011/10/12
We have analyzed the new Rossi X-ray Timing Explorer Proportional Counter Array data of the atoll neutron star (NS) low-mass X-ray binary (LMXB) system XB 1254-690. The colour-colour diagram shows tha...
Multimessenger astronomy with pulsar timing and X-ray observations of massive black hole binaries
Black hole physics – Accretion, accretion discs – Gravitational waves –pulsars: general – X-rays: general
2011/10/9
We demonstrate that very massive (>10^8\msun), cosmologically nearby (z<1) black hole binaries (MBHBs), which are primary targets for ongoing and upcoming pulsar timing arrays (PTAs), are particularly...
GRAVITAS : General Relativistic Astrophysics VIa Timing And Spectroscopy: An ESA M3 mission proposal
General Relativistic Astrophysics Spectroscopy mission proposal
2011/9/28
GRAVITAS is an X-ray observatory, designed and optimised to address the ESA Cosmic Vision theme of "Matter under extreme conditions". It was submitted as a response to the call for M3 mission proposal...
