Deformed black hole immersed in dark matter spike

Understand

If a lot of dark matter particles accumulate near the black hole, then the chances of detecting dark matter signals near a black hole are greatly increased.

• These effects may be observed by the Event Horizon Telescope (EHT), Tianqin project, Taiji project, Laser Interferometer Space Antenna (LISA) and Laser Interferometer Gravitational-Wave Observatory (LIGO).
• In this work, we explore the effects of dark matter spikes on black hole space-time.
• For the Schwarzschild-like black hole case, we consider Newton$'$s approximation and perturbation approximation.
