Photometry, Centroid and Point-Spread Function Measurements in the LSST Camera Focal Plane Using Artificial Stars

Posted by dbos Stanford

Kavli Affiliate: Stuart Marshall | First 5 Authors: Johnny H. Esteves, Yousuke Utsumi, Adam Snyder, Theo Schutt, Alex Broughton | Summary: The Vera C. Rubin Observatory’s LSST Camera (LSSTCam) pixel response has been characterized using laboratory measurements with a grid of artificial stars. We quantify the contributions to photometry, centroid, point-spread function size, and shape […]

Lack of near-sightedness principle in non-Hermitian systems

Posted by dbos Delft

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Anton R. Akhmerov, Ion Cosma Fulga, | Summary: The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its […]

Supermassive Primordial Black Holes From Inflation

Posted by dbos Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, Albert Stebbins, | Summary: There is controversy surrounding the origin and evolution of our universe’s largest supermassive black holes (SMBHs). In this study, we consider the possibility that some of these black holes formed from the direct collapse of primordial density […]
