# Black hole shadow of a rotating scale--dependent black hole

## TL;DR

This paper derives a rotating black hole solution from a scale-dependent spherically symmetric black hole, analyzes its horizon and causality, and investigates the shape of its shadow, contributing to understanding black hole imaging.

## Contribution

It introduces a novel rotating black hole solution using the Newman-Janis algorithm without complexification for scale-dependent gravity models.

## Key findings

- The shape of the black hole shadow is characterized and discussed.
- The horizon and causality conditions of the rotating solution are analyzed.
- A new rotating black hole metric is constructed from a static, scale-dependent black hole.

## Abstract

In this work, starting from a spherically symmetric scale--dependent black hole, a rotating solution is obtained by following the Newman--Janis algorithm without complexification. Besides studying the horizon, the static conditions and causality issues of the rotating solution, we get and discuss the shape of its shadow.
