AGN STORM 2: X. The origin of the interband continuum delays in Mrk 817

Hagai Netzer, Michael R. Goad, Aaron J. Barth +26

The local (z=0.0315) AGN Mrk 817, was monitored over more than 500 days with space-borne and ground-based instruments as part of a large international campaign AGN STORM 2. Here, w…

AGN STORM 2. VII. A Frequency-resolved Map of the Accretion Disk in Mrk 817: Simultaneous X-ray Reverberation and UVOIR Disk Reprocessing Time Lags

Collin Lewin, Erin Kara, Aaron J. Barth +35

X-ray reverberation mapping is a powerful technique for probing the innermost accretion disk, whereas continuum reverberation mapping in the UV, optical, and infrared (UVOIR) revea…

The impact of void-finding algorithms on galaxy classification

Fatima Zaidouni, Dahlia Veyrat, Kelly A. Douglass +1

We explore how the definition of a void influences the conclusions drawn about the impact of the void environment on galactic properties using two void-finding algorithms in the Vo…
