Lightcurves of 20--100 kilometer Kuiper Belt Objects using the Hubble Space Telescope
David E. Trilling, Gary M. Bernstein
We report high precision photometry of three small and one larger Kuiper Belt Objects (KBOs) obtained with the Advanced Camera for Surveys onboard the Hubble Space Telescope (ACS/H…
PSF Anisotropy and Systematic Errors in Weak Lensing Surveys
Bhuvnesh Jain, Mike Jarvis, Gary Bernstein
Given the basic parameters of a cosmic shear weak lensing survey, how well can systematic errors due to anisotropy in the point spread function (PSF) be corrected? The largest sour…
Inhomogeneous systematic signals in cosmic shear observations
Jacek Guzik, Gary Bernstein
We calculate the systematic errors in the weak gravitational lensing power spectrum which would be caused by spatially varying calibration (i.e. multiplicative) errors, such as mig…
The Shear TEsting Programme 1: Weak lensing analysis of simulated ground-based observations
Catherine Heymans, Ludovic Van Waerbeke, David Bacon +22
The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wid…
Dark Energy Constraints from the CTIO Lensing Survey
Mike Jarvis, Bhuvnesh Jain, Gary Bernstein +1
We perform a cosmological parameter analysis of the 75 square degree CTIO lensing survey in conjunction with CMB and Type Ia supernovae data. For Lambda CDM cosmologies, we find th…
