In this manuscript, we explore the concept of dark matter black holes, inspired by the Einasto density profile in the background of $f(\mathcal{G})$ gravity, where $\mathcal{G}$ is a Gauss-Bonnet invariant. This work extends the scope beyond the noncommutative tiny black hole structure which incorporates dark matter as a constituent forming the black hole. Our investigation demonstrates the feasibility of constructing black hole solutions for various Einasto index values, $f(\mathcal{G})$ gravity parameters, and parameters of mass function adopting anisotropic fluid configuration to characterize the matter sector. Specifically, by adopting an equation of state in which the radial pressure equals the negative of the energy density, we derive black hole solutions exhibiting a horizon structure with the central singularity replaced by a regular de Sitter core akin to the Reissner-Nordstr"{o}m black holes. Furthermore, we explore an alternative scenario where the equation of state is nonlocal, resulting in the construction of self-gravitating fuzzy dark matter droplets together with the dark source $f(\mathcal{G})$ corrections.

In this work, we consider the collapse of a $\mathbb{D}$-dimensional sphere in the framework of a higher dimensional spherically symmetric space-time in which the gravitational action chosen is claimed to be somehow linked to the $\mathbb{D}$-dimensional modified term.This work investigates the criteria for dynamical instability ofanisotropic relativistic sphere systems with$\mathbb{D}$-dimensional modified gravity. The certain conditions areapplied that lead to the collapse equation and their effects onadiabatic index $\Gamma$ in both Newtonian (N) and Post-Newtonian(PN) regimes by using a perturbation scheme. The study explores thatthe $\Gamma$ plays a crucial role in determining the degree ofdynamical instability. This index characterizes the fluid'sstiffness and has a significant i7mpact on defining the ranges ofinstability. This systematic investigation demonstrates theinfluence of various material properties such as anisotropicpressure, kinematic quantities, mass function, $\mathbb{D}$-dimensional modified gravity parameters, and the radial profile of energy density on theinstability of considered structures during their evolution. Thiswork also displays the dynamical behavior of spherically symmetricfluid configuration via graphical approaches.
