|Searching for helical magnetic fields in the Milky Way Galaxy|
|by Jennifer West (Dunlap Institute)|
Abstract: The origin and 3D structure of
magnetic fields on galactic scales is an unsolved mystery. Leading
theoretical models of large-scale galactic magnetic fields come from
dynamo theory, which predicts the presence of helicity in these
fields. In this talk, I will describe a possible observational
signature of helicity in the Milky Way magnetic field that relies on
polarization data from large scale radio surveys.
I wwill also discuss the Canadian Initiative for Radio Astronomy Data Analysis (CIRADA). CIRADA is a new project that will take basic data products from large scale radio surveys such as those from ASKAP, VLASS, and CHIME, and create new enhanced data products, which will be made accessible to the scientific community via sophisticated digital databases.
