Nondh Panithanpaisal is a postdoctoral researcher at Carnegie Observatories. His research focuses on disrupted star clusters known as stellar streams. Using state-of-the-art cosmological baryonic simulations of Milky Way-mass galaxies, he identifies and studies dwarf galaxy streams to constrain the nature of dark matter and near-field cosmology. At Carnegie, his research aims to develop numerical simulations that include globular cluster streams, which can be used to indicate the presence of dark-matter substructures within our own Galaxy.
