{ "abstract": "Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolution of these correlations requires precise measurements of the masses of distant black holes. We observed the gravitationally lensed quiescent galaxy MRG-M0138 at redshift 1.95 using James Webb Space Telescope integral field spectroscopy to spatially resolve the kinematics of stars within the black hole's sphere of influence. By using a foreground lens model and fitting stellar dynamical models, we determined the mass of its inactive black hole to be [Formula: see text] solar masses. Comparing this measurement to local galaxies, we found that [Formula: see text] is higher than expected given the galaxy's bulge mass but consistent with the correlation of [Formula: see text] with stellar velocity dispersion.", "abstract_shown": true, "affiliations": [ "Department of Physics and Astronomy, University of Southern California, Los Angeles, CA, USA", "Observatories, Carnegie Institution for Science, Pasadena, CA, USA", "Department of Physics, The University of Hong Kong, Hong Kong, China", "Dipartimento di Fisica e Astronomia, Università di Bologna, Bologna, Italy", "Department of Physics & Astronomy, University College London, London, UK", "Department of Astrophysical Sciences, Princeton University, Princeton, NJ, USA", "Department of Physics and Astronomy, Texas A&M University, College Station, TX, USA", "George P. and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy, Texas A&M University, College Station, TX, USA", "Max-Planck-Institut für Astrophysik, Garching, Germany", "School of Natural Sciences, Technical University of Munich, Garching, Germany", "Dipartimento di Fisica e Scienze della Terra, Università degli Studi di Ferrara, Ferrara, Italy", "Dipartimento di Fisica, Università degli Studi di Milano, Milano, Italy", "Institute of Cosmology and Gravitation, University of Portsmouth, Portsmouth, UK", "Instituto di Astrofisica Spaziale e Fisica cosmica Milano, Istituto Nazionale di Astrofisica, Milano, Italy", "Centre for Astrophysics and Supercomputing, Swinburne University of Technology, Hawthorn, Victoria, Australia", "Department of Physics & Astronomy, University of California Riverside, Riverside, CA, USA", "NASA Ames Research Center, Moffett Field, CA, USA", "SETI Institute, Mountain View, CA, USA", "Leiden Observatory, Leiden University, Leiden, Netherlands", "Infrared Processing and Analysis Center, California Institute of Technology, Pasadena, CA, USA", "Space Telescope Science Institute, Baltimore, MD, USA", "Instituto de Física de Cantabria, Santander, Spain", "Osservatorio di Astrofisica e Scienza dello Spazio di Bologna, Istituto Nazionale di Astrofisica, Bologna, Italy", "Department of Astronomy, Yonsei University, Seoul, Korea", "School of Earth and Space Exploration, Arizona State University, Tempe, AZ, USA", "Department of Astronomy and Steward Observatory, University of Arizona, Tucson, AZ, USA", "Center for Frontier Science, Chiba University, Chiba, Japan", "Department of Physics and Astronomy, University of California Davis, Davis, CA, USA", "Department of Physics, Ben-Gurion University of the Negev, Be’er-Sheva, Israel", "Department of Physics, Graduate School of Science, Chiba University, Chiba, Japan" ], "article_type": null, "arxiv": null, "author_total": 37, "authors": [ { "affs": [ 0, 1 ], "name": "Andrew B.
