A 4~Kpc Molecular Gas Lane in Cygnus A
C. L. Carilli, R. A. Perley, D. A. Perley +4
We present the discovery of a 4 kpc molecular gas lane in the Cygnus A host galaxy, using ALMA CO 2-1 observations. The gas lane is oriented roughly perpendicular to the projected…
Imaging the AGN Torus in Cygnus
C. L. Carilli, R. A. Perley, V. Dhawan +1
We present the first direct imaging of what may be the thick torus in the active galactic nucleus (AGN) of the archetype powerful radio galaxy Cygnus A, using the Jansky Very Large…
Discovery of a Luminous Radio Transient 460 pc from the Central Supermassive Black Hole in Cygnus A
Daniel A. Perley, Richard A. Perley, Vivek Dhawan +1
We report the appearance of a new radio source at a projected offset of 460 pc from the nucleus of Cygnus A. The flux density of the source (which we designate Cygnus A-2) rose fro…
Astrometry of Cassini with the VLBA to Improve the Saturn Ephemeris
Dayton L. Jones, William M. Folkner, Robert A. Jacobson +4
Planetary ephemerides have been developed and improved over centuries. They are a fundamental tool for understanding solar system dynamics, and essential for planetary and small bo…
An evolving compact jet in the black hole X-ray binary MAXI J1836-194
D. M. Russell, T. D. Russell, J. C. A. Miller-Jones +27
We report striking changes in the broadband spectrum of the compact jet of the black hole transient MAXI J1836-194 over state transitions during its discovery outburst in 2011. A f…
VLBI constraints on the "jet-line" of Cygnus X-1
Anthony Rushton, James Miller-Jones, Zsolt Paragi +7
Results are presented from recent VLBI observations of Cygnus X-1 during X-ray spectral state changes. Using the EVN in e-VLBI mode and the VLBA with disk recording, we observed th…
