Synthetic Observations of Magnetic Fields in Protostellar Cores
Joyce W. Y. Lee, Charles L. H. Hull, Stella S. R. Offner
The role of magnetic fields in the early stages of star formation is not well constrained. In order to discriminate between different star formation models, we analyze 3D magnetohy…
880 m SMA polarization observations of the quasar 3C 286
Charles L. H. Hull, Josep M. Girart, Qizhou Zhang
For decades, the bright radio quasar 3C 286 has been widely recognized as one of the most reliable polarization calibrators at centimeter wavelengths because of its unchanging pola…
Interferometric mapping of magnetic fields: The ALMA view of the massive star forming clump W43-MM1
Paulo C. Cortes, Josep M. Girart, Charles Hull +6
Here we present the first results from ALMA observations of 1 mm polarized dust emission towards the W43-MM1 high mass star forming clump. We have detected a highly fragmented fila…
An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1
Charles L. H. Hull, Josep M. Girart, Lars E. Kristensen +6
We report ALMA observations of a one-sided, high-velocity (80 km s) CO() jet powered by the intermediate-mass protostellar source Serpens SMM1-a.…
ALMA Science Verification Data: Millimeter Continuum Polarimetry of the Bright Radio Quasar 3C 286
H. Nagai, K. Nakanishi, R. Paladino +6
We present full-polarization observations of the compact, steep-spectrum radio quasar 3C~286 made with the ALMA at 1.3~mm. These are the first full-polarization ALMA observations,…
