A QPO in Mkn 421 from Archival RXTE Data

Evan Smith, Lani Oramas, Eric Perlman

We report a 325(-7, +8) day quasi-periodic oscillation (QPO) in the X-ray emission of the blazar Mkn 421, based on data obtained with the Rossi X-ray Timing Explorer (RXTE). The QP…

Variability of extragalactic X-ray jets on kiloparsec scales

Eileen T. Meyer, Aamil Shaik, Yanbo Tang +10

Unexpectedly strong X-ray emission from extragalactic radio jets on kiloparsec scales has been one of the major discoveries of Chandra, the only X-ray observatory capable of sub-ar…

I. Reconstructing Three-Dimensional Jet Geometry from Two-Dimensional Images

Sailee M. Sawant, Katie Kosak, Kunyang Li +3

We present a three-dimensional (3-D) visualization of jet geometry using numerical methods based on a Markov Chain Monte Carlo (MCMC) and limited memory Broyden-Fletcher-Goldfarb-S…

Lightcurve Evolution of the nearest Tidal Disruption Event: A late-time, radio-only flare

Eric S. Perlman, Eileen T. Meyer, Q. Daniel Wang +6

Tidal disruption events (TDEs) occur when a star passes close enough to a galaxy's supermassive black hole to be disrupted by tidal forces. We discuss new observations of IGRJ12580…

A QPO in NGC 4945 from Archival RXTE Data

Evan Smith, Rebecca Robles, Eric Perlman

We report the discovery of a ~6-week quasi-periodic oscillation (QPO) in archival NGC 4945 data observed by the Rossi X-ray Timing Explorer (RXTE) satellite. QPOs are an important…
