GRUMPY: a simple framework for realistic forward-modelling of dwarf galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]

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

Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana Botti, Mariano Cababie, Gustavo Cancelo | 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 […]

CathAI: Fully Automated Interpretation of Coronary Angiograms Using Neural Networks

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Robert Avram, Jeffrey E. Olgin, Alvin Wan, Zeeshan Ahmed, Louis Verreault-Julien | Summary: Coronary heart disease (CHD) is the leading cause of adult death in the United States and worldwide, and for which the coronary angiography procedure is the primary gateway for diagnosis and clinical management decisions. […]

Quantum Computing by Cooling

Kavli Affiliate: Frank Wilczek | First 5 Authors: Jiajin Feng, Biao Wu, Frank Wilczek, , | Summary: Interesting problems in quantum computation take the form of finding low-energy states of (pseudo)spin systems with engineered Hamiltonians that encode the problem data. Motivated by the practical possibility of producing very low-temperature spin systems, we propose and exemplify […]

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

Kavli Affiliate: T. A. Shutt | First 5 Authors: R. Linehan, R. L. Mannino, A. Fan, C. M. Ignarra, S. Luitz | 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 […]

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

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 […]
