Multi-band ALMA Polarization Observations of BHB07-11 Reveal Aligned Dust Grains in Complex Spiral Arm Structures
Austen Fourkas, Leslie W. Looney, Zhe-Yu Daniel Lin +8
Polarization-mode observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are powerful tools for studying the dust grain populations in circumstellar disks. Many…
FIELDMAPS Data Release: Far-Infrared Polarization in the "Bones" of the Milky Way
Simon Coudé, Ian W. Stephens, Philip C. Myers +13
Polarization observations of the Milky Way and many other spiral galaxies have found a close correspondence between the orientation of spiral arms and magnetic field lines on scale…
The Hourglass-shaped Magnetic Fields and Dust Filaments in the HH 211 Protostellar Envelope
Youngwoo Choi, Woojin Kwon, Leslie W. Looney +4
Magnetic fields influence the structure and evolution of protostellar systems, thus understanding their role is essential for probing the earliest stages of star formation. We pres…
First results from ALPPS: a sub-Alfvénic streamer in SVS13A
P. C. Cortes, J. E. Pineda, T. -H. Hsieh +22
We present the first results from the ALMA Perseus Polarization Survey (ALPPS), focusing on the magnetic field in the SVS13A circumbinary disk. The dataset includes full-Stokes dus…
Detailed radial scale height profile of dust grains as probed by dust self-scattering in HL Tau
Haifeng Yang, Ian W. Stephens, Zhe-Yu Daniel Lin +4
The vertical settling of dust grains in a circumstellar disk, characterized by their scale height, is a pivotal process in the formation of planets. This study offers in-depth anal…
Magnetic Fields in the Pillars of Creation
Adwitiya Sarkar, Leslie W. Looney, Marc W. Pound +7
Due to dust grain alignment with magnetic fields, dust polarization observations of far-infrared emission from cold molecular clouds are often used to trace magnetic fields, allowi…
