Description

The ULDM wave-like behavior is known to cause dynamical heating of stars. We investigate this effect on typical dwarf galaxy systems, with emphasis on Fornax, via numerical simulations. We show that kinematics data are in tension with an ULDM mass of m < 1e-21 eV. Extension to lower velocity dispersion systems may push the constrain to higher masses.
