Friday's EVN Seminar: High resolution observations of magnetic fields in the Central Molecular Zone of the Galactic Center
| Submitter: | Benito Marcote |
| Description: | Today we have a new EVN seminar at 16:00 CET! Cornelia C. Lang, from the University of Iowa, will talk about High resolution observations of magnetic fields in the Central Molecular Zone of the Galactic Center. The talk will be 35-40 min long, followed by a Q&A and discussion session. Attendants can join via Zoom (Meeting ID: 885 4531 2932). The talk will also be streamed in real time via YouTube in the JIVE and EVN channel. Abstract: In addition to harboring a supermassive black hole at its very core, the Galactic center is one of the most physically extreme environments in the Galaxy. Dense and massive molecular clouds on non-circular orbits are abundant in this region, yet star formation is not as active and frequent as expected. In addition, radio observations have revealed a population of synchrotron-emitting filaments that provide insight on the magnetic field strength and configuration in this unique region of the Galaxy. I will review observational results from several recent studies undertaken by my research group: we have examined the properties and kinematics of a group of unusual molecular clouds that appear to be part of an orbital “stream” of material around the Galactic center. In addition, we have been studying the detailed structure of the synchrotron-emitting radio filaments and their connection to larger-scale energetic outflows from the Galactic center. Our relative proximity to the Galactic center provides an unprecedented view of a galactic core and studies of this region can be used as an astrophysical analog to understanding the nuclei of more distant galaxies. |
