The Effect of Spiral Structure on the Measurements of the Oort Constants
I. Minchev, A. Quillen
We perform test-particle simulations in a 2D, differentially rotating stellar disk, subjected to a two-armed steady state spiral density wave perturbation in order to estimate the…
Chaotic zone boundary for low free eccentricity particles near an eccentric planet
Alice C. Quillen, Peter Faber
We consider particles with low free or proper eccentricity that are orbiting near planets on eccentric orbits. Via collisionless particle integration we numerically find the locati…
Predictions for a planet just inside Fomalhaut's eccentric ring
Alice C. Quillen
We propose that the eccentricity and sharpness of the edge of Fomalhaut's disk are due to a planet just interior to the ring edge. The collision timescale consistent with the disk…
Hubble Space Telescope Near-Infrared Snapshot Survey of 3CR radio source counterparts at low redshift
Juan P. Madrid, Marco Chiaberge, David Floyd +9
We present newly acquired images of the near-infrared counterpart of 3CR radio sources. All the sources were selected to have a redshift of less than 0.3 to allow us to obtain the…
An optical-IR jet in 3C133
David J. E. Floyd, Robert Laing, Marco Chiaberge +10
We report the discovery of a new optical-IR synchrotron jet in the radio galaxy 3C133 from our HST/NICMOS snapshot survey. The jet and eastern hotspot are well resolved, and visibl…
Discovery of a 500 pc shell in the nucleus of Centaurus A
Alice C. Quillen, Joss Bland-Hawthorn, Mairi H. Brookes +5
Spitzer Space Telescope mid-infrared images of the radio galaxy Centaurus A reveal a shell-like, bipolar, structure 500 pc to the north and south of the nucleus. This shell is seen…
Spitzer observations of the dusty warped disk of Centaurus A
Alice C. Quillen, Mairi H. Brookes, Jocelyn Keene +3
Spitzer mid-infrared images of the dusty warped disk in the galaxy Centaurus A show a parallelogram-shaped structure. We successfully model the observed mid-infrared morphology by…
