A numerical study of observational systematic errors in lensing analysis of CMB polarization

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Ryo Nagata, Toshiya Namikawa, , , | Summary: Impacts of observational systematic errors on the lensing analysis of the cosmic microwave background (CMB) polarization are investigated by numerical simulations. We model errors of gain, angle, and pointing in observation of the CMB polarization and simulate polarization fields […]

R-process-rich stellar streams in the Milky Way

Kavli Affiliate: Anna Frebel | First 5 Authors: Maude Gull, Anna Frebel, Karina Hinojosa, Ian U. Roederer, Alexander P. Ji | Summary: We present high-resolution Magellan/MIKE spectra of 22 bright ($9<V<13.5$) metal-poor stars ($-3.18<mbox{[Fe/H]}<-1.37$) in three different stellar streams, the Helmi debris stream, the Helmi trail stream, and the $omega$ Centauri progenitor stream. We augment […]

Evidence for a high-energy tail in the gamma-ray spectra of globular clusters

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Deheng Song, Oscar Macias, Shunsaku Horiuchi, Roland M. Crocker, David M. Nataf | Summary: Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes–curvature radiation from millisecond pulsar magnetospheres vs. inverse Compton emission from […]

Adversarial Learning with Cost-Sensitive Classes

Kavli Affiliate: Ran Wang | First 5 Authors: Haojing Shen, Sihong Chen, Ran Wang, Xizhao Wang, | Summary: It is necessary to improve the performance of some special classes or to particularly protect them from attacks in adversarial learning. This paper proposes a framework combining cost-sensitive classification and adversarial learning together to train a model […]

Hamiltonian Gotay-Nester-Hinds analysis of the parametrized unimodular extension of the Holst action

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, | Summary: We give a detailed account of the Hamiltonian GNH analysis of the parametrized unimodular extension of the Holst action. The purpose of the paper is to derive, through the clear geometric picture […]

The MUSE Hubble Ultra Deep Field Survey XVI. The angular momentum of low-mass star-forming galaxies. A cautionary tale and insights from TNG50

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nicolas F. Bouché, Shy Genel, Alisson Pellissier, Cédric Dubois, Thierry Contini | Summary: We investigate the specific angular momentum (sAM) $ j(<r)$ profiles of intermediate redshift ($0.4<z<1.4$) star-forming galaxies (SFGs) in the relatively unexplored regime of low masses (down to $M_starsim 10^8$M$_{odot}$), and small sizes (down to […]

Certifying Numerical Decompositions of Compact Group Representations

Kavli Affiliate: David Gross | First 5 Authors: Felipe Montealegre-Mora, Denis Rosset, Jean-Daniel Bancal, David Gross, | Summary: We present a performant and rigorous algorithm for certifying that a matrix is close to being a projection onto an irreducible subspace of a given group representation. This addresses a problem arising when one seeks solutions to […]

Automated Insulin Delivery for Type 1 Diabetes Mellitus Patients using Gaussian Process-based Model Predictive Control

Kavli Affiliate: Francis J. Doyle | First 5 Authors: Lukas Ortmann, Dawei Shi, Eyal Dassau, Francis J. Doyle III, Berno J. E. Misgeld | Summary: The human insulin-glucose metabolism is a time-varying process, which is partly caused by the changing insulin sensitivity of the body. This insulin sensitivity follows a circadian rhythm and its effects […]
