Dark Matter with Dwarf Galaxies: Challenges and Prospects at Small Mass Scales
speaker: Kohei Hayashi (Sendai College)
Abstract:
Dwarf galaxies, as low-mass systems dominated by dark matter, serve as ideal laboratories for investigating the fundamental nature of dark matter. Their structural and dynamical properties offer a unique window into the distribution of dark matter on small mass scales. However, revealing their dark matter profiles requires not only a large number of precise stellar kinematic measurements, but also a careful treatment of the systematic uncertainties inherent in dynamical modeling.
In this talk, I will present current efforts to constrain the dark matter density profiles of dwarf galaxies through dynamical analyses of available spectroscopic data. I will also discuss future prospects for this field, emphasizing anticipated improvements in both observational data quality and modeling techniques.
