A Search for Molecular Gas in GHz Peaked Spectrum Radio Sources
C. P. O'Dea, J. Gallimore, C. Stanghellini +2
We present searches for molecular gas (CO, OH, CS, and Ammonia) in six GHz Peaked Spectrum (GPS) radio sources. We do not detect gas in any source and place upper limits on the mas…
The Parsec-scale Radio Structure of NGC 1068 and the Nature of the Nuclear Radio Source
Jack F. Gallimore, Stefi A. Baum, Christopher P. O'Dea
We present sensitive, multifrequency Very Long Baseline Array (VLBA) images of the nuclear radio sources of NGC 1068. At 5 GHz and 8.4 GHz, the radio continuum source S1, argued to…
Comparison of Radio Observations and Numerical Simulations of the Radio Lobes of Cygnus A
J. C. Carvalho, R. A. Daly, M. P. Mory +1
We present a comparison of radio observations of the archetypal powerful radio galaxy Cygnus A and 2-D numerical hydrodynamical simulations. We characterize some global trends in t…
Exploring the Nucleus of the Gigamaser Galaxy TXS 2226-184
G. B. Taylor, A. B. Peck, J. S. Ulvestad +1
We present Very Long Baseline Array (VLBA) observations of the Gigamaser galaxy TXS2226-184 at 1.3 and 5 GHz. These observations reveal the parsec-scale radio structure of this Sey…
