Dehnen halo effect on a black hole in an ultra-faint dwarf galaxy

Understand

There had been recent advancement toward the detection of ultra-faint dwarf galaxies, which may serve as a useful laboratory for dark matter exploration since some of them contains almost 99$\%$ of pure dark matter.

• The majority of these galaxies contain no black hole that inhabits them.
• Recently, there had been reports that some dwarf galaxies may have a black hole within.
• In this study, we construct a black hole solution combined with the Dehnen dark matter halo profile, which is commonly used for dwarf galaxies.
