Sources of contamination to weak lensing tomography: redshift-dependent shear measurement bias
Elisabetta Semboloni, Ismael Tereno, Ludovic van Waerbeke +1
The current methods available to estimate gravitational shear from astronomical images of galaxies introduce systematic errors which can affect the accuracy of weak lensing cosmolo…
STAGES: the Space Telescope A901/2 Galaxy Evolution Survey
M. E. Gray, Christian Wolf, Marco Barden +26
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution ac…
The STAGES view of red spirals and dusty red galaxies: Mass-dependent quenching of star-formation in cluster infall
Christian Wolf, Alfonso Aragon-Salamanca, Michael Balogh +22
We investigate the properties of optically passive spirals and dusty red galaxies in the A901/2 cluster complex at redshift ~0.17 using restframe near-UV-optical SEDs, 24 micron IR…
Near-Infrared spectral diagnostics for unresolved stellar population galaxies
M. Cesetti, V. D. Ivanov, L. Morelli
We want to develop spectral diagnostics of stellar populations in the near-infrared (NIR), for unresolved stellar populations. We created a semi-empirical population model and we c…
Sersiclets - A Matched Filter Extension of Shapelets for Weak Lensing Studies
Wai-Hin Wayne Ngan, Ludovic Van Waerbeke, Andisheh Mahdavi +2
The precision study of dark matter using weak lensing by large scale structure is strongly constrained by the accuracy with which one can measure galaxy shapes. Several methods hav…
Obscured star formation in intermediate-density environments: A Spitzer study of the Abell 901/902 supercluster
A. Gallazzi, E. F. Bell, C. Wolf +23
We explore the amount of obscured star-formation as a function of environment in the A901/902 supercluster at z=0.165 in conjunction with a field sample drawn from the A901 and CDF…
