Cosmic Shear from STIS pure parallels: III. Analysis of Cycle 9 pure parallels
J. -M. Miralles, T. Erben, H. Haemmerle +4
Following the detection of a cosmic shear signal at the 30'' scale using archival parallel data from the STIS CCD camera onboard HST in Haemmerle et al. (2002), we analyzed a large…
Flat-fielding of ACS WFC grism data
N. Pirzkal, A. Pasquali, J. Walsh
In direct imaging, broad band flat-fields can easily be applied to correct deviation from uniform sensitivity across the detector field. However for slitless spectroscopy data the…
The Wavelength Calibration of the WFC grism
A. Pasquali, N. Pirzkal, J. R. Walsh
We present the wavelength solution derived for the G800L grism with the Wide Field Channel from the spectra of two Galactic Wolf-Rayet stars, WR 45 and WR 96. The data were acquire…
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.…
