The chemical abundance pattern of the extremely metal-poor thin disk star 2MASS J1808-5104 and its origins

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Rana Ezzeddine, Anirudh Chiti, Yohai Meiron | Summary: We present a high-resolution ($Rsim35,000$), high signal-to-noise ($S/N=350$) Magellan/MIKE spectrum of the bright extremely metal-poor star 2MASS~J1808$-$5104. We find [Fe/H] = $-$4.01 (spectroscopic LTE stellar parameters), [Fe/H] = $-$3.8 (photometric stellar parameters), [Fe/H] […]

Interpretable Uncertainty Quantification in AI for HEP

Kavli Affiliate: Brian Nord | First 5 Authors: Thomas Y. Chen, Biprateep Dey, Aishik Ghosh, Michael Kagan, Brian Nord | Summary: Estimating uncertainty is at the core of performing scientific measurements in HEP: a measurement is not useful without an estimate of its uncertainty. The goal of uncertainty quantification (UQ) is inextricably linked to the […]

JWST NIRCam+NIRSpec: Interstellar medium and stellar populations of young galaxies with rising star formation and evolving gas reservoirs

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sandro Tacchella, Benjamin D. Johnson, Brant E. Robertson, Stefano Carniani, Francesco D’Eugenio | Summary: We present an interstellar medium and stellar population analysis of three spectroscopically confirmed $z>7$ galaxies in the ERO JWST/NIRCam and JWST/NIRSpec data of the SMACS J0723.3-7327 cluster. We use the Bayesian spectral energy […]

Modelling TES non-linearity induced by a rotating HWP in a CMB polarimeter

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Tommaso Ghigna, Tomotake Matsumura, Yuki Sakurai, Ryota Takaku, Kunimoto Komatsu | Summary: Most upcoming CMB experiments are planning to deploy between a few thousand and a few hundred thousand TES bolometers in order to drastically increase sensitivity and unveil the B-mode signal. Differential systematic effects and $1/f$ […]

Learning to Re-weight Examples with Optimal Transport for Imbalanced Classification

Kavli Affiliate: Zhuo Li | First 5 Authors: Dandan Guo, Zhuo Li, Meixi Zheng, He Zhao, Mingyuan Zhou | Summary: Imbalanced data pose challenges for deep learning based classification models. One of the most widely-used approaches for tackling imbalanced data is re-weighting, where training samples are associated with different weights in the loss function. Most […]

Non-Gaussianity effects on the primordial black hole abundance for sharply-peaked primordial spectrum

Kavli Affiliate: Misao Sasaki | First 5 Authors: Takahiko Matsubara, Misao Sasaki, , , | Summary: We perturbatively study the effect of non-Gaussianities on the mass fraction of primordial black holes (PBHs) at the time of formation by systematically taking its effect into account in the one-point probability distribution function of the primordial curvature perturbation. […]

A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called "quasiparticle poisoning." Recently, a superconductor with one […]
