Comprehensive and robust analysis of galaxies found throughout cosmic time provides the means to probe the underlying characteristics of our Universe. Coupling observations and theory, spectral energy...
Rotational X-ray tracking uncovers hidden motion at the nanoscale
Rotational X-ray tracking hidden motion nanoscale
2014/6/12
Over the past two decades or so, there has been increasing interest and development in measuring slow dynamics in disordered systems at the nanoscale, brought about in part from a demand for advanceme...
Intrinsic disc emission and the Soft X-ray Excess in AGN
X-rays: accretion discs black hole physics
2011/10/18
Narrow Line Seyfert 1 (NLS1) galaxies have low mass black holes and mass accretion rates close to (or exceeding) Eddington, so a standard blackbody accretion disc should peak in the EUV. However, the ...
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...

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...
The Be/X-ray binary A0535+26 during its recent 2009/2010 outbursts
Be/X-ray binary A0535+26 during recent 2009/2010 outbursts
2011/10/10
The Be/X-ray binary A0535+26 showed a giant outburst in December 2009 that reached ~5.14 Crab in the 15-50 keV range. Unfortunately, due to Sun constraints it could not be observed by most X-ray satel...
