• Deep Synoptic Array science: a 50 Mpc fast radio burst constrains the mass of the Milky Way circumgalactic medium

-- We derive a conservative upper limit on the DM contributed by the circumgalactic medium (CGM) of the Milky Way:
-- the limit is either 28.7 pc cm−3 and 47.3 pc cm−3,
--- depending on which of two pulsars nearby on the sky to FRB 20220319D is used to estimate the ISM DM.
-- These limits both imply that the total Galactic CGM mass is <1011M⊙,
-- and that the baryonic mass of the Milky Way is ≲60% of the cosmological average given the total halo mass.
-- The results strongly support scenarios commonly predicted by galaxy-formation simulations wherein feedback processes expel baryonic matter from the halos of galaxies like the Milky Way.
