\item robishaw+08 measure splitting at 1667 in 5 ULIRGS w/ Arecibo+GBT (8 in survey)  \item B_LOS ~ .5 - 18 mG -- similar to galactic ones, suggesting local massive star formation is similar in starbursts  \item similar to B measured from synch radiation -- fields pervade multiple ISM phases  \item Equation 2 in robishaw+08 for B_LOS -- adapted Equation 1 in mcbride heiles 13  \item Some profiles show multiple components -- total of 14 individual components (spatial)  \item 1667 dominates over 1665, despite measuring similar B values to galactic -- maybe due to wider extragalactic maser lines  \item in Arp 220 - 4 spots - 2 w/ fields toward us and 2 w/ fields away  \item VLBI follow-up would give high-resolution field maps of B about the nucleus - robishaw heiles 09  \item additional 11 confident detections - mcbride heiles 13, 6.1-27.6 mG  \item new detections suggest larger than typical galactic B-fields -- median of 12 mG, ~2 larger than the Fish et al 2005  \item used all confirmed targets from Darling paper III and Willett 2012  \item Some non-detections may be due to much larger B, where the narrow line width approx doesn't hold  \item Can constrain some dynamics -- spherical cloud stability inferred suggests B plays a significant role in region dynamics, lws of ~20 km/s from Parra et al 05 in III Zw35 suggest non-gravitationally bound clouds. Magnetic support may keep confinement (not unlike some proposed schemes for cloud substructure)  \item McBride+14 include other B estimates from other methods, determine that ISM B-fields are greater in ULIRGs  \item dependent on minimum energy argument holding in the center of starburst galaxies  \item u_B > u_photon -- synchrotron cooling dominates over inverse Compton cooling -- CR electrons radiate energy via synchroton before leaving galaxy  \end{itemize}  \subsection{Cosmology}
