Rotating black hole in Rastall theory

Understand

Rotating black hole solutions in theories of modified gravity are important as they offer an arena to test these theories through astrophysical observation.

• The non-rotating black hole can be hardly tested since the black hole spin is very important in any astrophysical process.
• We present rotating counterpart of a recently obtained spherically symmetric exact black hole solution surrounded by perfect fluid in the context of Rastall theory, viz, rotating Rastall black hole that generalize the Kerr-Newman black hole solution.
• In turn, we analyze the specific cases of the Kerr-Newman black holes surrounded by matter like dust and quintessence fields.
