Example of a bipolar outflow in IRAS 15557-5215 region. The top panels show the moment-0 map (left) and moment-1 map (right) of HC3N line. The outflow axis is represented by thin blue (for blue-shifted lobe) and red arrows (for red-shifted lobe) in the moment maps, and the position of 3 mm dust continuum core (host core) is marked with a yellow ellipse. The red-shifted and blue-shifted components of the emission are also shown with red and blue contours, respectively. The bottom panels show the moment-2 map (left, with a color bar above it) and the PV diagram along the outflow axis (right). The vertical and horizontal cyan dashed lines represent the position and the Vlsr of the host core, respectively. -- astro-ph.GA

The ALMA-ATOMS Survey: Exploring Protostellar Outflows In HC3N

by Keith CowingMay 14, 2025May 14, 2025

We present the first systematic study of bipolar outflows using HC3N as a tracer in a sample of 146 massive star-forming regions from ALMA-ATOMS survey.
