Evidence for crust cooling in the transiently accreting 11-Hz X-ray pulsar in the globular cluster Terzan 5
globular clusters: individual (Terzan 5) - X-rays: binaries - stars: neutron -pulsars: individual (CXOGClb J174804.8–244648, IGR J17480–2446)
2011/10/17
The temporal heating and subsequent cooling of the crusts of transiently accreting neutron stars carries unique information about their structure and a variety of nuclear reaction processes. We report...
MAXI GSC monitoring of the Crab nebula and pulsar during the GeV gamma-ray flare in September 2010

2011/10/12
We report on the MAXI GSC X-ray monitoring of the Crab nebula and pulsar during the GeV gamma-ray flare for the period of 2010 September 18-24 (MJD 55457-55463) detected by AGILE and Fermi-LAT. There ...
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...
