Astropulse: A Search for Microsecond Transient Radio Signals Using Distributed Computing. I. Methodology

J. Von Korff, P. Demorest, E. Heien +7

We are performing a transient, microsecond timescale radio sky survey, called "Astropulse," using the Arecibo telescope. Astropulse searches for brief (0.4 μs to 204.8 μs), wideban…

Atmospheric PSF Interpolation for Weak Lensing in Short Exposure Imaging Data

C. Chang, P. J. Marshall, J. G. Jernigan +25

A main science goal for the Large Synoptic Survey Telescope (LSST) is to measure the cosmic shear signal from weak lensing to extreme accuracy. One difficulty, however, is that wit…
