Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations
A. Jana, C. Ricci, M. J. Temple +7
Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
The NuSTAR Local AGN Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe
Peter G. Boorman, Poshak Gandhi, Johannes Buchner +33
Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compt…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla Bontà, B. M. Peterson, C. J. Grier +19
The goal of this project is to construct an estimator for the masses of supermassive black holes in active galactic nuclei (AGNs) based on the broad Halpha emission line. We make u…
Kinematic analysis of galaxies in the SPT234956 protocluster core
Aparna Venkateshwaran, Axel Weiss, Nikolaus Sulzenauer +10
SPT234956 is a protocluster discovered in the 2500 deg South Pole Telescope (SPT) survey. In this paper, we study the kinematics of the galaxies found in the core of SPT2349…
Numerical Modeling of Galactic Superwinds with Time-evolving Stellar Feedback
A. Danehkar, M. S. Oey, W. J. Gray
Mass-loss and radiation feedback from evolving massive stars produce galactic-scale superwinds, sometimes surrounded by pressure-driven bubbles. Using the time-dependent stellar po…
A refined search for high-velocity gas in the Cygnus Loop supernova remnant
Adam M. Ritchey, S. R. Federman, David L. Lambert
We present the results of a sensitive search for high-velocity gas in interstellar absorption lines associated with the Cygnus Loop supernova remnant (SNR). We examine high-resolut…
