The Seoul National University AGN Monitoring Project III: H lag measurements of 32 luminous AGNs and the high-luminosity end of the size--luminosity relation

Jong-Hak Woo, Shu Wang, Suvendu Rakshit +28

We present the main results from a long-term reverberation mapping campaign carried out for the Seoul National University Active Galactic Nuclei (AGN) Monitoring Project. High-qual…

Connecting Low- and High-Redshift Weak Emission-Line Quasars via HST Spectroscopy of Ly Emission

Jeremiah D. Paul, Richard M. Plotkin, Ohad Shemmer +10

We present ultraviolet spectroscopy covering the Ly + N V complex of six candidate low-redshift () weak emission-line quasars (WLQs) based on observations with th…

Ultraviolet and X-ray Properties of Coma's Ultra-Diffuse Galaxies

Chris H. Lee, Edmund Hodges-Kluck, Elena Gallo

Many ultra-diffuse galaxies (UDGs) have been discovered in the Coma cluster, and there is evidence that some, notably Dragonfly 44, have Milky Way-like dynamical masses despite dwa…

Nuclear X-ray Activity in Low-Surface-Brightness Galaxies: Prospects for Constraining the Local Black Hole Occupation Fraction with a Chandra Successor Mission

Edmund Hodges-Kluck, Elena Gallo, Anil Seth +2

About half of nearby galaxies have a central surface brightness >1 magnitude below that of the sky. The overall properties of these low-surface-brightness galaxies (LSBGs) remain u…

Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395

Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31

We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…

Accretion-Driven Sources in Spatially Resolved Ly Emitters

B. Dittenber, M. S. Oey, E. Hodges-Kluck +4

Ly emission is a standard tracer of starburst galaxies at high redshift. However, a number of local Ly emitters (LAEs) are X-ray sources, suggesting a possible origin of Ly$α…
