Tensor Completion with BMD Factor Nuclear Norm Minimization

Kavli Affiliate: Eric Miller | First 5 Authors: Fan Tian, Mirjeta Pasha, Misha E. Kilmer, Eric Miller, Abani Patra | Summary: This paper is concerned with the problem of recovering third-order tensor data from limited samples. A recently proposed tensor decomposition (BMD) method has been shown to efficiently compress third-order spatiotemporal data. Using the BMD, […]

Observed epochal variations in X-ray lines from the O Supergiant $ζ$ Puppis do not require substantial changes in the wind mass flux

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Kenneth G. Gayley, David P. Huenemoerder, Pragati Pradhan, Nathan A. Miller | Summary: We fit the high resolution textit{Chandra} X-ray spectra of the O supergiant $zeta$ Puppis using the variable boundary condition (VBC) line model to test the stability of its mass-loss rate […]

Stick to your Role! Stability of Personal Values Expressed in Large Language Models

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Rémy Portelas, Masataka Sawayama, Peter Ford Dominey, Pierre-Yves Oudeyer | Summary: The standard way to study Large Language Models (LLMs) through benchmarks or psychology questionnaires is to provide many different queries from similar minimal contexts (e.g. multiple choice questions). However, due to LLM’s highly context-dependent […]

Evidence for Episodic Black Hole Growth of Reionization-Era Quasars observed with Magellan/FIRE

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Leah Bigwood, Anna-Christina Eilers, Robert A. Simcoe, , | Summary: Observations of high-redshift quasars hosting billion solar mass black holes at $zgtrsim6$ challenge our understanding of early supermassive black hole (SMBH) growth. In this work, we conduct a near-infrared spectroscopic study of $19$ quasars at $6.2lesssim […]

A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows

Kavli Affiliate: Ronald Remillard | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]

Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek, Itai Linial, Petra Sukova | Summary: Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underlying physical mechanism is a […]
