The Launching of Cosmic Ray Driven Outflows

PrincetonUniversity/athena 24 May 2021

When streaming is present, most of the transferred energy takes the form of Alfv\'{e}n wave heating of the gas, raising its pressure and internal energy, with a lower fractional contribution to the kinetic energy of the outflow.

$B$-mode forecast of CMB-Bh$\overline{a}$rat

dfm/emcee 24 Oct 2021

For a simplistic foreground model (only polarized dust and synchrotron), both component separation pipelines can achieve the desired sensitivity of ECHO, i. e. $\sigma (r =0) \sim (0. 4 - 0. 7)\times 10^{-3}$.
