Polarimetry of Compact Symmetric Objects
N. E. Gugliucci, G. B. Taylor, A. B. Peck +1
We present multi-frequency VLBA observations of two polarized Compact Symmetric Objects (CSOs), J0000+4054 and J1826+1831, and a polarized CSO candidate, J1915+6548. Using the wave…
New H2O masers in Seyfert and FIR bright galaxies
C. Henkel, A. B. Peck, A. Tarchi +4
Extragalactic water vapor masers with 50, 1000, 1, and 230 solar (isotropic) luminosities were detected toward Mrk1066 (UGC2456), Mrk34, NGC3556 and Arp299, respectively. The inter…
Dating COINS: Kinematic Ages for Compact Symmetric Objects
N. E. Gugliucci, G. B. Taylor, A. B. Peck +1
We present multi-epoch VLBA observations of Compact Symmetric Objects (CSOs) from the COINS sample (CSOs Observed In the Northern Sky). These observations allow us to make estimate…
High resolution imaging of the radio continuum and neutral gas in the inner kiloparsec of the radio galaxy 3C293
R. J. Beswick, A. B. Peck, G. B. Taylor +1
Using a combination of observations involving the VLA, MERLIN and global VLBI networks we have made a detailed study of the radio continuum and the neutral hydrogen (HI) kinematics…
HI absorption at the center of NGC2146
A. Tarchi, A. Greve, A. B. Peck +4
We present 1.4 GHz HI absorption line observations towards the starburst in NGC2146, made with the VLA and MERLIN. The HI gas has a rotating disk/ring structure with column densiti…
A Masing Molecular Cloud in the Central Parsecs of Mrk348
A. B. Peck, C. Henkel, J. S. Ulvestad
We report new observations of the H_2O megamaser in the Seyfert 2 galaxy Mrk348. The line is redshifted by about 130 km s^-1 with respect to the systemic velocity, is extremely bro…
