The Large Observatory for X-ray Timing (LOFT)
Missions X-ray timing compact objects black holes neutron stars
2011/9/27
High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultra-dense matter and to black hole masses and spins. A 10 m^2-cl...
Atmospheric optical-turbulence at Roque de los Muchachos Observatory: database and recalibration of the generalized-SCIDAR data
Atmospheric effects? instrumentation: adaptive optics? Site Testing
2011/9/13
We present the largest database so far of atmospheric optical-turbulence profiles(197035 individual C2N(h)) for an astronomical site, the Roque de los Muchachos Observatory (La Palma, Spain). This C2 ...

In spite of being located at the heart of the highest mountain range in the world, the Himalayan Nepal Climate Observatory (5079 m a.s.l.) at the Ev-K2-CNR Pyramid is shown to be affected by the advec...
The high-redshift Universe with the International X-ray Observatory
Galaxies active – X-rays Active Galactic Nuclei – galaxies high-redshift
