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…

UV/Optical disk reverberation lags despite a faint X-ray corona in the AGN Mrk 335

Erin Kara, Aaron J. Barth, Edward M. Cackett +37

We present the first results from a 100-day Swift, NICER and ground-based X-ray/UV/optical reverberation mapping campaign of the Narrow-Line Seyfert 1 Mrk 335, when it was in an un…

A complex dust morphology in the high-luminosity AGN Mrk 876

Hermine Landt, Jake A. J. Mitchell, Martin J. Ward +9

Recent models for the inner structure of active galactic nuclei (AGN) advocate the presence of a radiatively accelerated, dusty outflow launched from the outer regions of the accre…

Bayesian Analysis of Quasar Lightcurves with a Running Optimal Average: New Time Delay Measurements of COSMOGRAIL Gravitationally Lensed Quasars

Fergus R. Donnan, Keith Horne, Juan V. Hernández Santisteban

We present a new method of modelling time-series data based on the running optimal average (ROA). By identifying the effective number of parameters for the ROA model, in terms of t…

Discovery of UV millisecond pulsations and moding in the low mass X-ray binary state of transitional millisecond pulsar J1023+0038

Amruta D. Jaodand, Juan V. Hernández Santisteban, Anne M. Archibald +7

PSR J1023+0038 is a rapidly-spinning neutron star with a low-mass-binary companion that switches between a radio pulsar and low-luminosity disk state. In 2013, it transitioned to i…

Intensive disc-reverberation mapping of Fairall 9: 1st year of Swift & LCO monitoring

J. V. Hernández Santisteban, R. Edelson, K. Horne +33

We present results of time-series analysis of the first year of the Fairall 9 intensive disc-reverberation campaign. We used Swift and the Las Cumbres Observatory global telescope…
