Measuring Magnetic Fields Near and Far with the SKA via the Zeeman Effect
Timothy Robishaw, Marta Nowotka, Tao-Chung Ching +7
Zeeman splitting in spectral lines -- both in emission and absorption -- provides direct estimates of magnetic field strength and direction in magnetized gas in our own Milky Way a…
Measuring Magnetic Field Strengths in Galactic Star-forming Regions via the Zeeman Effect with the SKA
Tyler L. Bourke, Tao-Chung Ching, Laura Fissel +14
Magnetic fields thread the interstellar medium from the largest to the smallest scales and play an important role in molecular cloud evolution and star formation. Quantifying this…
Star Formation Drives Production of Low Energy Cosmic Rays
Ningyu Tang, Jiahao Liu, Di Li +18
For over a century, the origin of low-energy cosmic rays (LECRs), the dominant heaters and ionizers of dense interstellar gas, remains elusive owing to solar modulation and uncerta…
ALMA Polarization Study of the Magnetic Fields in Two Massive Clumps in the 20 km s Cloud of the Central Molecular Zone
Yuhua Liu, Xing Lu, Junhao Liu +14
We present the Atacama Large Millimeter/submillimeter Array (ALMA) observations of linearly polarized 870 m continuum emission at a resolution of 0.2 (20…
Pinched Magnetic Fields in the High-mass Protocluster W3 IRS5
Huei-Ru Vivien Chen, Qizhou Zhang, Tao-Chung Ching +2
We present polarization maps of dust emission at 340 GHz in the luminous high-mass protocluster, W3 IRS5, observed with the Submillimeter Array. The projected magnetic fields appea…
Joint Analysis of HI Absorption Zeeman Measurements and the Morphology of Filamentary HI Emission
Marta Nowotka, Susan E. Clark, Blakesley Burkhart +4
We present a joint analysis of HI absorption Zeeman measurements and the morphology of filamentary HI emission to investigate the three-dimensional structure of the magnetic field…
