We present a study of the vertical magnetic field of the Milky Way towards the Galactic poles, determined from observations of Faraday rotation toward more than 1000 polarized extragalactic radio sources at Galactic latitudes |b| > 77 degs,…

There was an expectation that the magnetic field direction would rotate dramatically across the heliopause (HP). This rotation was used as one of the criteria to determine if Voyager 1 (V1) had crossed the HP. Recently the Voyager team…
