The ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its
maturity. It is clearly able to describe the universe at large scale, even if some issues remain …

The majority of the matter in the universe is still unidentified and under investigation by both
direct and indirect means. Many experiments searching for the recoil of dark-matter particles …

Not long ago, a novel gravitational scheme ie, 4 D-EGB (Einstein-Gauss-Bonnet) gravity
have been proposed by Glavan and Lin 2020. They rescaled the coupling factor α with α D-4 …

Circumambient and galactic-scale environments are intermittently present around black
holes, especially those residing in active galactic nuclei. As supermassive black holes …

General relativity predicts that black holes are described by the Kerr metric, which has
integrable geodesics. This property is crucial to produce accurate waveforms from extreme …

This paper is based on lectures given at the IX Mexican School on Gravitation and
Mathematical Physics. The lectures (as the paper) were a broad-band review of the current …

This review aims at proposing to the field an overview of the Cusp-core problem, including a
discussion of its advocated solutions, assessing how each can satisfactorily provide a …

We study the structure of compact objects that contain non-self annihilating, self-interacting
dark matter admixed with ordinary matter made of neutron star and white dwarf materials …

Motivated by the increasing interest in models which consider scalar fields as viable dark
matter candidates, we have constructed a generalization of relativistic boson btars (BS) …

The aim of this work is to provide a general description of the corpuscular theory of gravity.
After reviewing some of the major conceptual issues emerging from the semiclassical and …
