Probing the polarization characteristics of SS433 on mas scales
Z. Paragi, R. C. Vermeulen, D. C. Homan +5
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear…
Influence of UV radiation from a massive YSO on the chemistry of its envelope
P. Stauber, S. D. Doty, E. F. van Dishoeck +2
We have studied the influence of far ultraviolet (UV) radiation from a massive young stellar object (YSO) on the chemistry of its own envelope by extending the models of Doty et al…
Probing Pre-Protosellar Cores with Formaldehyde
Kaisa E. Young, Jeong-Eun Lee, Neal J. Evans +2
We present maps of the 6 cm and 1.3 mm transitions of formaldehyde toward three cold, dense pre-protostellar cores: L1498, L1512, and L1544. The 6 cm transition is a unique probe o…
Locality and information transfer in quantum operations
Benjamin Schumacher, Michael D. Westmoreland
We investigate the situation in which no information can be transferred from a quantum system B to a quantum system A, even though both interact with a common system C.
Sub-milliarcsecond Imaging of Quasars and Active Galactic Nuclei III. Kinematics of Parsec-Scale Radio Jets
K. I. Kellermann, M. L. Lister, D. C. Homan +6
We report the results of a 15 GHz (2 cm) multi-epoch VLBA program, begun in 1994 to study the outflow in radio jets ejected from quasars and active galaxies. The observed flow of 2…
Physical-chemical modeling of the low-mass protostar IRAS 16293-2422
S. D. Doty, F. L. Schoeier, E. F. van Dishoeck
We present detailed gas-phase chemical models for the envelope of the low-mass star-forming region IRAS 16293-2422. By considering both time- and space-dependent chemistry, these m…
