- Title
- Outflow-associated Massive Young Stellar Objects: ALMA/VLA Comparative Study of G35.20?0.74N and G35.03+0.35
- Abstract
- We present the results of a comparative study of very large array (VLA) centimeter and ALMA millimeter observations of G35.20?0.74N and G35.03+0.35. In G35.20?0.74N, we detected a single 1.3 cm continuum (free-free) emission in B-north, coinciding in position with the 3.6 cm and 0.86 mm continuum, but neither 1.3 cm nor 0.86 mm continuum was found toward B-south. This implies that the driving source(s) of B core is within or near B-north, and B-south is not a YSO. The geometrical alignment of B-south with the north-south jet traced at 3.6 cm tends to suggest that B-south could be a newly ejected, flux-density enhanced clump in the jet. In G35.03+0.35, we detected multiple 0.86 mm cores and also prominent hot shocked gas traced by SiO around the southeast 44 GHz CH3OH, NH3 (3,3) and (6,6) maser strong peaks of Brogan et al. (2011). This could be a signature of the high-velocity gas outflow, associated with NE1 millimeter core, traced by 12CO.

- Title
- Masers and turbulence
- Abstract
-
I will briefly describe observational data on the images and spectra for masers of different types, make a brief review of using masers as a tools to study characteristics of interstellar turbulence consider how the maser images and spectra are formed in the turbulent medium, compare results of the modelling with the observational data,and briefly consider how the turbulence can affect accuracy of the parallax measurements. I will also introduce recent results on masers
obtained within framework of the RadioAstron project. - Facilitator
