High-Spectral Resolution Observations of the Optical Filamentary Nebula in NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +18
We present new high-spectral resolution observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, the central galaxy of the Perseus cluster. These observatio…
The Case for Hot-Mode Accretion in Abell 2029
Deovrat Prasad, G. Mark Voit, Brian W. O'Shea
Radiative cooling and AGN heating are thought to form a feedback loop that regulates the evolution of low redshift cool-core galaxy clusters. Numerical simulations suggest that for…
ReveaLLAGN 0: First Look at JWST MIRI data of Sombrero and NGC 1052
K. Goold, A. Seth, M. Molina +28
We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGN. We focus on two observations with th…
Investigating the Dark Matter Halo of NGC 5128 using a Discrete Dynamical Model
Antoine Dumont, Anil C. Seth, Jay Strader +7
As the nearest accessible massive early-type galaxy, NGC 5128 presents an exceptional opportunity to measure dark matter halo parameters for a representative elliptical galaxy. Her…
RadioAstron Space VLBI Imaging of the jet in M87: I. Detection of high brightness temperature at 22 GHz
Jae-Young Kim, Tuomas Savolainen, Petr Voitsik +19
We present results from the first 22 GHz space very-long-baseline interferometric (VLBI) imaging observations of M87 by RadioAstron. As a part of the Nearby AGN Key Science Program…
A variable active galactic nucleus at triply-imaged by the galaxy cluster MACS J0035.4-2015
Lukas J. Furtak, Ramesh Mainali, Adi Zitrin +32
We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4-2015 (). The object is detected in Hubble…
