    Untangling Magellanic Streams

    Untangling Magellanic Streams by Dennis Zaritsky, Vedant Chandra, Charlie Conroy, Ana Bonaca, Phillip A. Cargile, Rohan P. Naidu

    Published 2025-02-01

    The Magellanic Stream (MS) is known to contain multiple H<small>I</small> strands and corresponding stellar populations are being discovered. Combining a sample of 17 stars from the H3 (“Hectochelle in the Halo at High Resolution”) survey with 891 stars drawn from the <em>Gaia<...

    All-sky Kinematics of the Distant Halo: The Reflex Response to the LMC

    All-sky Kinematics of the Distant Halo: The Reflex Response to the LMC by Vedant Chandra, Rohan P. Naidu, Charlie Conroy, Nicolas Garavito-Camargo, Chervin Laporte, Ana Bonaca, Phillip A. Cargile, Emily Cunningham, Jiwon Jesse Han, Benjamin D. Johnson, Hans-Walter Rix, Yuan-Sen Ting, Rebecca Woody, Dennis Zaritsky

    Published 2025-01-01

    The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent “reflex motion” on the observed velocities of distant halo stars. We construct the largest all-sky spectroscopic data set of luminous red giant stars from 50–160 kpc, including a...

    A Large Catalog of DA White Dwarf Characteristics Using SDSS and Gaia Observations

    A Large Catalog of DA White Dwarf Characteristics Using SDSS and Gaia Observations by Nicole R. Crumpler, Vedant Chandra, Nadia L. Zakamska, Gautham Adamane Pallathadka, Stefan Arseneau, Nicola Gentile Fusillo, J. J. Hermes, Carles Badenes, Priyanka Chakraborty, Boris T. Gänsicke, Sean Morrison, Hans-Walter Rix, Stephen P. Schmidt, Axel Schwope, Keivan G. Stassun

    Published 2025-01-01

    We present a catalog of 8545 and 19,257 unique DA white dwarfs (WDs) observed in Sloan Digital Sky Survey (SDSS) Data Release 19 and previous SDSS data releases, respectively. This is the largest catalog of both spectroscopic and photometric measurements of DA WDs available to date, and we make this...
