We explore the dynamics of thin accretion disks, the radius of blackhole shadows, observed intensities, and the visual characteristicsof Born-Infeld BTZ black holes in massive gravity. We find out therelations for angular velocity, specific energy, and angularmomentum of particles around the black hole. We observe that intenseBorn-Infeld electromagnetic effects lead to a reduction in therotational motion of particles within the accretion disk, and themassive gravity slows down the orbital motion of these particles. Wereveal that the influence of massive gravity parameter correlateswith a reduction in the black hole's shadow size, which suggeststhat massive gravity effects intensify the gravitational fields,thereby reducing the angular diameter of the shadows. On the otherhand, a higher Born-Infeld parameter enlarges the black hole'sshadow, which manifests a visual relationship between the blackhole's physical dimensions and its gravitational influence.Moreover, we also uncover the optical characteristics of Born-InfeldBTZ black holes, which show that the Born-Infeld parameter greatlyinfluences the electromagnetic field around the black hole, whichaffects energy distribution in the space. Finally, we observe thatmassive gravity significantly influences the spacetime structurenear black holes, which is crucial for grasping gravitationallensing and the dynamics of accretion disks under such extremeconditions.

Motivated by the impact of the phantom field (or anti-Maxwell field) on the structure of three-dimensional black holes in the presence of the cosmological constant, we present the first extraction of solutions for the phantom BTZ (A)dS black hole. In this study, we analyze the effect of the phantom field on the horizon structure. Furthermore, we compare the BTZ black holes in the presence of both the phantom and Maxwell fields. Additionally, we calculate the conserved and thermodynamic quantities of the phantom BTZ black holes, demonstrating their compliance with the first law of thermodynamics. Subsequently, we assess the effects of the electrical charge and the cosmological constant on the local stability in the canonical ensemble by considering these fields with respect to the heat capacity. We then investigate the global stability area of the BTZ black holes with phantom and Maxwell fields within the grand canonical ensemble using Gibbs free energy. In this analysis, we evaluate the influence of the electrical charge and the cosmological constant on this area.

In a recent paper, black holes were viewed as topological thermodynamic defects using generalized off-shell free energy. The aforementioned work indicates that all black hole solutions in the pure Einstein–Maxwell gravity theory could be classified into three different topological classes for four and higher spacetime dimensions. In this paper, we investigate the topological number of BTZ black holes in distinct theories with different charges (Q) and rotational parameters (J). Using generalized free energy and Duan’s ϕ-mapping topological current theory, we found only two topological classes for BTZ spacetime. Particularly, for a BTZ black hole with rotation or in the Einstein–Power–Maxwell theory, there is only one zero point and the total topological number is 1. While for a BTZ black hole in new massive gravity, the global topological charge depends on the value of the specific parameter m, which provides a counter-example for the conjecture that the topological number is independent of the black hole’s parameters.
