On the phase-space structure of the Milky Way dark-matter halo
Amina Helmi, Volker Springel, Simon D. M. White
We analyse a high resolution simulation of the formation of a cluster's dark-matter halo in a CDM cosmology (Springel et al. 2001). The resolution achieved allows us to map the…
Cosmic Shear from STIS Pure Parallels: Analysis
H. Haemmerle, J. -M. Miralles, P. Schneider +5
The measurement of cosmic shear requires deep imaging with high image quality on many lines of sight to sample the statistics of large-scale structure. The expected distortion of g…
The cosmic shear STIS parallel program - First results
H. Haemmerle, J. -M. Miralles, P. Schneider +5
Since the Universe is inhomogeneous on scales well below the Hubble radius, light bundles from distant galaxies are deflected and distorted by the tidal gravitational field of the…
Detection of Cosmic Shear from STIS Parallel Archive Data: Data Analysis
J. -M. Miralles, H. Haemmerle, N. Pirzkal +6
In June 1997, parallel observations using the Space Telescope Imaging Spectrograph (STIS) on the HST started to be taken in substantial numbers along many different lines-of-sight.…
