The molecular emission from old supernova remnants
Antoine Gusdorf, Rolf Guesten, Sibylle Anderl +1
Supernovae constitute a critical source of energy input to the interstellar medium (ISM). In this short review, we focus on their latest phase of evolution, the supernova remnants…
Non-Zeeman Circular Polarization of CO rotational lines in SNR IC 443
Talayeh Hezareh, Helmut Wiesemeyer, Martin Houde +2
Context: We investigate non-Zeeman circular polarization and linear polarization levels of up to 1% of CO spectral line emission detected in a shocked molecular clump around…
Probing the Turbulent Ambipolar Diffusion Scale in Molecular Clouds with Spectroscopy
Talayeh Hezareh, Timea Csengeri, Martin Houde +2
We estimate the turbulent ambipolar diffusion length scale and magnetic field strength in the massive dense cores CygX-N03 and CygX-N53, located in the Cygnus-X star-forming region…
Non-Zeeman Circular Polarization of Molecular Rotational Spectral Lines
Martin Houde, Talayeh Hezareh, Scott Jones +1
We present measurements of circular polarization from rotational spectral lines of molecular species in Orion KL, most notably 12CO (J=2 - 1), obtained at the Caltech Submillimeter…
A search for co-evolving ion and neutral gas species in prestellar molecular cloud cores
Konstantinos Tassis, Talayeh Hezareh, Karen Willacy
Comparison of linewidths of spectral line profiles of ions and neutral molecules have been recently used to estimate the strength of the magnetic field in turbulent star-forming re…
Observational Determination of the Turbulent Ambipolar Diffusion Scale and Magnetic Field Strength in Molecular Clouds
Talayeh Hezareh, Martin Houde, Carolyn McCoey +1
We study the correlation of the velocity dispersion of the coexisting molecules H13CN and H13CO+ and the turbulent energy dissipation scale in the DR21(OH) star-forming region. The…
