Revealing AGNs Through TESS Variability

Helena P. Treiber, Jason T. Hinkle, Michael M. Fausnaugh +7

We used Transiting Exoplanet Survey Satellite (TESS) data to identify 29 candidate active galactic nuclei (AGNs) through their optical variability. The high-cadence, high-precision…

Variability Selected Active Galactic Nuclei from ASAS-SN Survey: Constraining the Low Luminosity AGN Population

Heechan Yuk, Xinyu Dai, T. Jayasinghe +5

Low luminosity active galactic nuclei (LLAGN) probe accretion physics in the low Eddington regime and can provide additional clues about galaxy evolution. AGN variability is ubiqui…

An Amusing Look at the Host of the Periodic Nuclear Transient ASASSN-14ko Reveals a Second AGN

M. A. Tucker, B. J. Shappee, J. T. Hinkle +10

We present Multi-Unit Spectroscopic Explorer (MUSE) integral-field spectroscopy of ESO 253G003, which hosts a known Active Galactic Nucleus (AGN) and the periodic nuclear transi…

Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548

P. R. Williams, A. Pancoast, T. Treu +155

We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…

Space Telescope and Optical Reverberation Mapping Project. IX. Velocity-Delay Maps for Broad Emission Lines in NGC 5548

Keith Horne, G. De Rosa, B. M. Peterson +155

We report velocity-delay maps for prominent broad emission lines, Ly_alpha, CIV, HeII and H_beta, in the spectrum of NGC5548. The emission-line responses inhabit the interior of a…

1ES 1927+654: An AGN Caught Changing Look on a Timescale of Months

Benny Trakhtenbrot, Iair Arcavi, Chelsea L. MacLeod +21

We study the sudden optical and ultraviolet (UV) brightening of 1ES 1927+654, which until now was known as a narrow-line active galactic nucleus (AGN). 1ES 1927+654 was part of the…
