The Optical Appearance of Compact Stars: Shadows and Luminous Ringsng theory of gravity, since it explore the regions where the gravitational field is extremely strong. In the images obtained by the collaboration, we can observe two distinct regions: a dark circular center called shadow and an enveloping luminous ring produced by the hot accretion disk surrounding

Beyond Newtonian Dynamics of Planar CRTBP with Kerr—Like Primariestext of a beyond-Newtonian approximation [.]. We shall begin by discussing the construction of the beyond-Newtonian potential in the so-called Fodor–Hoenselaers–Perjés procedure where we keep first order non-Newtonian contributions in both the mass and spin. Using this potential, we shall then discu

Introduction to Stellar and Substellar Physics in Modified Gravityerent forms of the polytropic equation of state. This allows to study a wide class of astrophysical objects in the framework of a given theory of gravity, as demonstrated in a few examples. We will discuss light elements burning processes and cooling models in stars and substellar objects with the u

Chameleon Perfect Scalar Field as a Geometric Correction in , Gravitym. Based on four statements, at the background and perturbative level, it is possible to relate the extra terms from this theory as a geometrical perfect fluid term, whose has been expressed as possible candidates to explain the nature of the dark sector, and possibly, in the case of a perfect scala

Entanglement in Conformal Field Theory and Holographyaldacena derivation of the Ryu-Takayanagi formula. The application to an ‘island set-up’ for the calculation of black hole radiation entropy is briefly discussed. Further topics focused on are the relation to thermal entropy, thermofield double constructions and statements about the emergence of gra

Coordinates are Messy—Not Only in General Relativityties such as the center of mass of an isolated gravitating system. We will argue that a similar phenomenon occurs in Newtonian Gravity once one ahistorically drops the restriction that one should only work in Cartesian coordinates when studying Newtonian Gravity. This will also shed light on the nat

Primordial Black Holes and Higgs Vacuum Decays change as the universe settles into its vacuum state. The discovery of the Higgs [., .], and measurement of its mass suggests that our vacuum may not be entirely stable, and that a further phase transition could take place. This article is based on a talk in the Oldenberg Series, and reviews how w

Hopi Beliefs of Wellness and UnwellnessThere is now compelling evidence that the fundamental interactions were once unified, but that, as the universe expanded and cooled, a series of symmetry-breaking phase transitions lead to their separation.
