The putative center in NGC 1052

Anne-Kathrin Baczko, Matthias Kadler, Eduardo Ros +284

Many active galaxies harbor powerful relativistic jets, however, the detailed mechanisms of their formation and acceleration remain poorly understood. To investigate the area of je…

RadioAstron probes the ultra-fine spatial structure in the HO maser emission in the star forming region W49N

N. N. Shakhvorostova, A. M. Sobolev, J. M. Moran +3

HO maser emission associated with the massive star formation region W49N were observed with the Space-VLBI mission RadioAstron. The procedure for processing of the maser spectr…

Sun-Sized Water Vapor Masers in Cepheus A

A. M. Sobolev, J. M. Moran, M. D. Gray +6

We present the first VLBI observations of a Galactic water maser (in Chepeus A) made with a very long baseline interferometric array involving the RadioAstron Earth-orbiting satell…

Discovery of Water Maser Emission in Eight AGN with 70-m Antennas of NASA's Deep Space Network

P. T. Kondratko, L. J. Greenhill, J. M. Moran +9

We report the discovery of water maser emission in eight active galactic nuclei (AGN) with the 70-m NASA Deep Space Network (DSN) antennas at Tidbinbilla, Australia and Robledo, Sp…

Submillimeter Array 440m/690GHz line and continuum observations of Orion-KL

H. Beuther, Q. Zhang, M. J. Reid +9

Submillimeter Array observations of Orion-KL at 1'' resolution in the 440mu/690GHz band reveal new insights about the continuum and line emission of the region. The 440mu continuum…

The Geometry of and Mass Accretion Rate through the Maser Accretion Disk in NGC 4258

J. R. Herrnstein, J. M. Moran, L. J. Greenhill +1

A maximum likelihood analysis of the NGC 4258 maser positions and velocities reveals a ~2 sigma deviation from Keplerian motion in the projected rotation curve of the high-velocity…
