JWST and Keck observations of the off-nuclear tidal disruption event TDE 2025abcr: An evolving reprocessing layer
Kishore C. Patra, Emily R. Liepold, Nicholas Earl +14
Off-nuclear tidal disruption events (TDEs) provide a rare probe of massive black holes (MBHs) outside galactic nuclei. Only a handful are known, including five X-ray-selected candi…
Mapping the Stellar Kinematics in the Central 240 Parsecs of M87 with the James Webb Space Telescope
Refa M. Al-Amri, Jonelle L. Walsh, Emily R. Liepold +2
The supermassive black hole (SMBH) in the giant elliptical galaxy M87 is one of the most well-studied in the local universe, but the stellar- and gas-dynamical SMBH mass measuremen…
The MASSIVE Survey. XX. A Triaxial Stellar Dynamical Measurement of the Supermassive Black Hole Mass and Intrinsic Galaxy Shape of Giant Radio Galaxy NGC 315
Jacob Pilawa, Emily R. Liepold, Chung-Pei Ma +2
We present a new dynamical measurement of the supermassive black hole mass and intrinsic shape of the stellar halo of the massive radio galaxy NGC 315 as part of the MASSIVE survey…
A 22-Billion Solar Mass Black Hole in Holmberg 15A with Keck KCWI Spectroscopy and Triaxial Orbit Modeling
Emily R. Liepold, Chung-Pei Ma, Jonelle L. Walsh
Holmberg 15A (H15A), the brightest cluster galaxy of Abell 85, has an exceptionally low central surface brightness even among local massive elliptical galaxies with distinct stella…
Big Galaxies and Big Black Holes: The Massive Ends of the Local Stellar and Black Hole Mass Functions and the Implications for Nanohertz Gravitational Waves
Emily R. Liepold, Chung-Pei Ma
We construct the galaxy stellar mass function (GSMF) by combining the GSMF at stellar masses from the census study of Leja et al. (2020) and…
