Astronomical Image Simulation for Telescope and Survey Development
Benjamin M. Dobke, David E. Johnston, Richard Massey +4
We present the 'simage' software suite for the simulation of artificial extragalactic images, based empirically around real observations of the Hubble Ultra Deep Field (UDF). The s…
Gravitational Lensing Accuracy Testing 2010 (GREAT10) Challenge Handbook
Thomas Kitching, Sreekumar Balan, Gary Bernstein +32
GRavitational lEnsing Accuracy Testing 2010 (GREAT10) is a public image analysis challenge aimed at the development of algorithms to analyze astronomical images. Specifically, the…
The Near-Infrared Sky Surveyor
Daniel Stern, James G. Bartlett, Mark Brodwin +11
[NIRSS is one of three concepts that contributed to the Wide-Field Infrared Survey Telescope (WFIRST) mission advocated by the Decadal Survey.] Operating beyond the reaches of the…
The Opacity of Galactic Disks at z~0.7
Mark T. Sargent, C. M. Carollo, P. Kampczyk +13
We compare the surface brightness-inclination relation for a sample of COSMOS pure disk galaxies at z~0.7 with an artificially redshifted sample of SDSS disks well matched to the C…
The effects of charge transfer inefficiency (CTI) on galaxy shape measurements
Jason Rhodes, Alexie Leauthaud, Chris Stoughton +4
(Abridged) We examine the effects of charge transfer inefficiency (CTI) during CCD readout on galaxy shape measurements required by studies of weak gravitational lensing. We simula…
