A1914
Velocity power spectra (PS) of the ICM are necessary for testing multi-scale physics in numerical simulations and measuring turbulent dissipation/plasma properties. XRISM allows direct studies of ICM kinematics, but the large PSF makes it challenging to extract PS. However, by combining high-resolution imaging and spectroscopic missions, one can calibrate indirect methods of measuring PS. We aim to test the relation between turbulent Mach numbers measured with XRISM and ICM density fluctuations probed with Chandra by observing two clusters, A2034/A1914, with 120/100 ks exposures. These clusters have dissimilar fluctuations measured over a wide scale range, which is ideal for our goal. This calibration will provide a robust method to measure velocity PS and probe ICM transport properties.
