Measuring the baryon fraction in cluster of galaxies with Kinematic Sunyaev Zeldovich and a Standard Candle

Understand

We propose a new method to use the kinematic Sunyaev-Zeldovich for measuring the baryon fraction in cluster of galaxies.

• In this proposal we need a configuration in which a supernova Type Ia resides in a brightest cluster galaxy of intermediate redshift clusters.
• We show this supernova Type Ia can be used to measure the bulk velocity of a galaxy cluster.
• We assert that the redshift range of $0.4<z<0.6$ is suitable for this proposal.
