A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications

Posted by klaurent July 21, 2014Stanford

Kavli Affiliate: Steven Kahn | First 5 Authors: Andrew Rasmussen, Pierre Antilogus, Pierre Astier, Chuck Claver, Peter Doherty | Summary: Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these requirements flow directly to the array of science imaging sensors at the […]

Witten Index and Wall Crossing

Posted by klaurent July 9, 2014Tokyo

Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Heeyeon Kim, Piljin Yi, , | Summary: We compute the Witten index of one-dimensional gauged linear sigma models with at least ${mathcal N}=2$ supersymmetry. In the phase where the gauge group is broken to a finite group, the index is expressed as a certain residue […]
