Spikey: Self-Lensing Flares from Eccentric SMBH Binaries
Betty X. Hu, Daniel J. D'Orazio, Zoltan Haiman +4
We examine the light curves of two quasars, motivated by recent suggestions that a supermassive black hole binary (SMBHB) can exhibit sharp lensing spikes. We model the variability…
Detection of Superluminal Motion in the X-Ray Jet of M87
Bradford Snios, Paul E. J. Nulsen, Ralph P. Kraft +5
Chandra HRC observations are investigated for evidence of proper motion and brightness changes in the X-ray jet of the nearby radio galaxy M87. Using images spanning 5 yr, proper m…
X-ray Studies of Exoplanets: A 2020 Decadal Survey White Paper
Scott J. Wolk, Jeremy J. Drake, Graziella Branduardi-Raymont +28
Over the last two decades, the discovery of exoplanets has fundamentally changed our perception of the universe and humanity's place within it. Recent work indicates that a solar s…
The tidal disruption event AT2017eqx: spectroscopic evolution from hydrogen rich to poor suggests an atmosphere and outflow
M. Nicholl, P. K. Blanchard, E. Berger +24
We present and analyse a new tidal disruption event (TDE), AT2017eqx at redshift z=0.1089, discovered by Pan-STARRS and ATLAS. The position of the transient is consistent with the…
The Advanced X-ray Imaging Satellite
Richard F. Mushotzky, James Aird, Amy J. Barger +41
Much of the baryonic matter in the Universe, including the most active and luminous sources, are best studied in the X-ray band. Key advances in X-ray optics and detectors have pav…
X-rays Studies of the Solar System
Bradford Snios, William R. Dunn, Carey M. Lisse +23
X-ray observatories contribute fundamental advances in Solar System studies by probing Sun-object interactions, developing planet and satellite surface composition maps, probing gl…
