Effect of Instrumental Polarization with a Half-Wave Plate on the $B$-Mode Signal: Prediction and Correction

Posted by klaurent Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Guillaume Patanchon, Hiroaki Imada, Hirokazu Ishino, Tomotake Matsumura, | Summary: We evaluate the effect of half-wave plate (HWP) imperfections inducing intensity leakage to the measurement of Cosmic Microwave Background (CMB) $B$-mode polarization signal with future satellite missions focusing on the tensor-to-scalar ratio $r$. The HWP is modeled […]

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 […]

Cosmological Distance Measurement of 12 Nearby Supernovae IIP with ROTSE-IIIB

Posted by klaurent Stanford

Kavli Affiliate: Eli Rykoff | First 5 Authors: Govinda Dhungana, Robert Kehoe, Ryan Staten, Jozsef Vinko, J. Craig Wheeler | Summary: We present cosmological analysis of 12 nearby ($z<0.06$) Type IIP supernovae (SNe IIP) observed with the ROTSE-IIIb telescope. To achieve precise photometry, we present a new image differencing technique that is implemented for the […]

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 […]
