SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD

Posted by klaurent Chicago

Kavli Affiliate: Michael Crisler | Summary:We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the origin of single-electron events in CCDs. We identify, separate, and quantify three independent contributions to the single-electron events, which were previously bundled together and classified as "dark […]

Controlling Neural Networks with Rule Representations

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Sungyong Seo, Sercan O. Arik, Jinsung Yoon, Xiang Zhang, Kihyuk Sohn | Summary: We propose a novel training method that integrates rules into deep learning, in a way the strengths of the rules are controllable at inference. Deep Neural Networks with Controllable Rule Representations (DeepCTRL) incorporates a […]

Design and production of the high voltage electrode grids and electron extraction region for the LZ dual-phase xenon time projection chamber

Posted by klaurent Stanford

Kavli Affiliate: T. A. Shutt | Summary:The dual-phase xenon time projection chamber (TPC) is a powerful tool for direct-detection experiments searching for WIMP dark matter, other dark matter models, and neutrinoless double-beta decay. Successful operation of such a TPC is critically dependent on the ability to hold high electric fields in the bulk liquid, across […]

Cosmology with Love: Measuring the Hubble constant using neutron star universal relations

Posted by klaurent Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Deep Chatterjee, Abhishek Hegade K. R., Gilbert Holder, Daniel E. Holz, Scott Perkins | Summary: Gravitational-wave cosmology began in 2017 with the observation of the gravitational waves emitted in the merger of two neutron stars, and the coincident observation of the electromagnetic emission that followed. Although […]

Chandra/LETGS Studies of the Collisional Plasma in 4U 1626-67

Posted by klaurent MIT

Kavli Affiliate: Norbert Schulz | Summary:We present an analysis of chandra/LETGS observations of the ultracompact X-ray binary (UCXB) 4U 1626$-$67, continuing our project to analyze the existing Chandra gratings data of this interesting source. The extremely low mass, hydrogen-depleted donor star provides a unique opportunity to study the properties and structure of the metal-rich accreted […]
