Description
Galaxy clusters are the largest gravitationally bound structures in the Universe, making them critical probes for cosmology. The distribution of clusters across mass and redshift allows us to constrain cosmological parameters such as the growth of structure, the total neutrino mass, and the matter density fraction. Accurate cluster mass measurements and calibrations of mass-observable scaling relations are essential in this process. In the first part of my poster, I will briefly show my recent work (Saha et al. 2023, arXiv:2307.11711) and discuss prospects for studying high-redshift clusters using CMB lensing with upcoming experiments like CMB-S4. In the second part, I will explore targeted observations of low- to mid-redshift clusters via NASA’s balloon-based imaging telescope, SuperBIT, where I am currently working on the shape-measurement pipeline and convergence map making from its shear observations.
