Modeling the upper kHz QPOs of 4U 1728-34 with X-ray reverberation
Benjamin M. Coughenour, Edward M. Cackett, Philippe Peille +1
While kilohertz quasi-periodic oscillations (kHz QPOs) have been well studied for decades since their initial discovery, the cause of these signals remains unknown, as no model has…
A Systematic Spectral-Timing Analysis of Kilohertz Quasi-Periodic Oscillations in the Rossi X-ray Timing Explorer Archive
Jon Troyer, Edward Cackett, Philippe Peille +1
Kilohertz quasi-periodic oscillations or kHz QPOs occur on the orbital timescale of the inner accretion flow and may carry signatures of the physics of strong gravity (c ~ GM…
Spectral-Timing Analysis of the Lower kHz QPO in the Low-Mass X-ray Binary Aquila X-1
Jon S. Troyer, Edward M. Cackett
Spectral-timing products of kilohertz quasi-periodic oscillations (kHz QPOs) in low-mass X-ray binary (LMXB) systems, including energy- and frequency-dependent lags, have been anal…
Correlated X-ray/Ultraviolet/Optical Variability in NGC 6814
Jon Troyer, David Starkey, Edward Cackett +4
We present results of a 3-month combined X-ray/UV/optical monitoring campaign of the Seyfert 1 galaxy NGC 6814. The object was monitored by Swift from June through August 2012 in t…
Swift/UVOT grism monitoring of NGC 5548 in 2013: an attempt at MgII reverberation mapping
E. M. Cackett, K. Gultekin, M. C. Bentz +4
Reverberation-mapping-based scaling relations are often used to estimate the masses of black holes from single-epoch spectra of AGN. While the radius-luminosity relation that is th…
