The Guitar’s Magnetic Field Revealed by Starlight Polarization

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: The Guitar nebula surrounding PSR B2224+65 boasts a pulsar X-ray filament likely aligned with the local magnetic field. We present new RoboPol stellar polarization data distributed along the line-of-sight to the pulsar. The polarizing effect of […]

An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN REJ1034+396

Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: We report the analysis of ~1Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus REJ1034+396. The 0.3-9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by […]

3D Radiative MHD Simulations of Starspots II: Large-scale Structure

Kavli Affiliate: Robert Cameron | First 5 Authors: Tanayveer Singh Bhatia, Mayukh Panja, Robert Cameron, Sami Solanki, | Summary: We compute realistic 3D radiative MHD near-surface models of starspots with substantial penumbrae on cool main-sequence stars using the MURaM simulation code. This work is an improvement on the the previous starspot models in a slab […]

Transcribing and Translating, Fast and Slow: Joint Speech Translation and Recognition

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Niko Moritz, Ruiming Xie, Yashesh Gaur, Ke Li, Simone Merello | Summary: We propose the joint speech translation and recognition (JSTAR) model that leverages the fast-slow cascaded encoder architecture for simultaneous end-to-end automatic speech recognition (ASR) and speech translation (ST). The model is transducer-based and uses a […]

Pointing Accuracy Improvements for the South Pole Telescope with Machine Learning

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: P. M. Chichura, A. Rahlin, A. J. Anderson, B. Ansarinejad, M. Archipley | Summary: We present improvements to the pointing accuracy of the South Pole Telescope (SPT) using machine learning. The ability of the SPT to point accurately at the sky is limited by its structural imperfections, […]

Using Felis to Represent the Semantics and Metadata of Astronomical Data Catalogs

Kavli Affiliate: Brian Van Klaveren | First 5 Authors: Jeremy McCormick, Gregory P. Dubois-Felsmann, Andrei Salnikov, Brian Van Klaveren, Tim Jenness | Summary: The Data Management team of the Vera C. Rubin Observatory has developed a data description language and toolset, Felis, for defining the semantics and metadata of its public-facing data catalogs. Felis uses […]

How do uncertainties in galaxy formation physics impact field-level galaxy bias?

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Mahlet Shiferaw, Nickolas Kokron, Risa H. Wechsler, , | Summary: Our ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy-dark matter halo relationship for a given galaxy population, which are governed by the intricacies of galaxy formation. To quantify these […]
