Uncovering the Origins of Spiral Structure by Measuring Radial Variation in Pattern Speeds
Sharon E. Meidt, Richard J. Rand, Michael R. Merrifield
Current theories of spiral and bar structure predict a variety of pattern speed behaviors, calling for detailed, direct measurement of the radial variation of pattern speeds. Our r…
The diversity of methanol maser morphologies from VLBI observations
A. Bartkiewicz, M. Szymczak, H. J. van Langevelde +2
We investigate which structures the 6.7 GHz methanol masers trace in the environment of high-mass protostar candidates by observing a homogenous sample of methanol masers selected…
Identifying Compact Symmetric Objects from the VLBA Imaging and Polarization Survey
S. E. Tremblay, G. B. Taylor, J. F. Helmboldt +2
Compact Symmetric Objects (CSOs) are small (less than 1 kpc) radio sources which have symmetric double lobes or jets. The dominant theory for the small size of these objects is tha…
Radio Continuum and Methanol Observations of DR21(OH)
Esteban D. Araya, Stan Kurtz, Peter Hofner +1
We report high sensitivity sub-arcsecond angular resolution observations of the massive star forming region DR21(OH) at 3.6, 1.3, and 0.7 cm obtained with the Very Large Array. In…
Disentangling the circumnuclear environs of Centaurus A: I. High resolution molecular gas imaging
D. Espada, S. Matsushita, A. Peck +8
We present high resolution images of the 12CO(2-1) emission in the central 1' (1 kpc) of NGC 5128 (Centaurus A), observed using the SMA. We elucidate for the first time the distrib…
