Mass dependence of halo baryon fractions from the kinetic Sunyaev-Zeldovich effect
The episode discusses a paper titled "Mass dependence of halo baryon fractions from the kinetic Sunyaev-Zeldovich effect." The hosts detail how low-mass galaxy groups are depleted in gas compared to expectations. They explain that this depletion is caused by energy processes like feedback, and the study's robust methodology provides a better benchmark for testing galaxy formation models.
