A New Robust Low‐Scatter X‐Ray Mass Indicator for Clusters of Galaxies
A New Robust Low‐Scatter X‐Ray Mass Indicator for Clusters of Galaxies
We present comparison of X-ray proxies for the total cluster mass, including the spectral temperature (Tx), gas mass measured within r500 (Mg), and the new proxy, Yx, which is a simple product of Tx and Mg and is related to the total thermal energy of the ICM. We use mock …
