The Role of Inner Halo Angular Momentum (Spin) in Shaping Dark Matter Bars in Milky Way Analogs
The episode discusses a paper investigating how dark matter halo spin, quantified by parameter lambda, shapes the formation and evolution of dark matter bars in Milky Way analogs. Hosts discuss how initial spin dictates bar strength and pattern speed, noting that higher prograde spin leads to stronger bars. The research suggests observational tests using gravitational lensing could constrain halo spin.
