    JWST Discovery of a Very Fast Biconical Outflow of Warm Molecular Gas in the Nearby Ultraluminous Infrared Galaxy F08572+3915 NW by Kylie Yui Dan, Jerome Seebeck, Sylvain Veilleux, David Rupke, Eduardo Gonzalez-Alfonso, Ismael Garcia-Bernete, Weizhe Liu, Dieter Lutz, Marcio Melendez, Miguel Pereira Santaella, Eckhard Sturm, Francesco Tombesi

    Published 2025-01-01
    “…The new JWST data bolster the scenario where the buried quasar in this ULIRG is excavating the dust screen, accelerating perhaps as much as 60% of the dusty warm molecular material to velocities beyond the escape velocity, and thus influencing the evolution of the host galaxy.…”

    Constraints on the Variation of the Fine-structure Constant at 3 < z < 10 with JWST Emission-line Galaxies by Linhua Jiang, Shuqi Fu, Feige Wang, Sarah E. I. Bosman, Zheng Cai, Hyunsung D. Jun, Zhiwei Pan, Fengwu Sun, Jinyi Yang, Huanian Zhang

    Published 2025-01-01
    “…While the constraints in this work are not as stringent as those from lower-redshift quasar absorption lines in previous studies, this work uses an independent tracer and provides the first constraints on Δ α / α at the highest redshifts. …”

    A Study on the Line of Sight to Galaxies Detected at Gamma-Ray Energies by Amy Furniss, Josepf N. Amador, Olivier Hervet, Ollie Jackson, David A. Williams

    Published 2025-01-01
    “…We measure the fraction of the line of sight that intersects voids for active galactic nuclei (AGN) detected by Fermi Large Area Telescope (LAT) and quasars from the Sloan Digital Sky Survey (SDSS). …”
