Fast Timing Analysis of Cygnus X-1 using SPI on board INTEGRAL
Analysis Cygnus board INTEGRAL
2011/9/29
For the very first time, we report the high frequency analysis of Cyg X-1 up to hard X-ray using SPI on-board INTEGRAL. After analyzing the possible contribution fromthe background, and using INTEGRAL...
GRAVITAS : General Relativistic Astrophysics VIa Timing And Spectroscopy: An ESA M3 mission proposal
General Relativistic Astrophysics Spectroscopy mission proposal

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...
The Stellar Archeology of the M33 Disk: Recent Star-Forming History and Constraints on the Timing of an Interaction with M31
galaxies evolution — galaxies spiral — galaxies
2011/8/24
Images recorded with MegaCam are used to investigate the recent star-forming history (SFH) of the Local Group Sc galaxy M33. The properties of the stellar disk change near R = 8 kpc. Within this radiu...

Assessing the Role of Spin Noise in the Precision Timing of Millisecond Pulsars
the Role of Spin Noise the Precision Timing
2011/1/10
We investigate rotational spin noise (referred to as timing noise) in non-accreting pulsars: millisecond pulsars, canonical pulsars, and magnetars. Particular attention is placed on quantifying the st...
