Mimetic Gravity: A Review of Recent Developments and Applications to Cosmology and Astrophysics

by General Relativity is, at best, incomplete. The concordance cosmology model suggests a scenario where only ~4% of the energy budget of the universe consists of baryonic matter, whereas ~24% consists ... is very puzzling and might be hinting to a more profound structure. It thus appears that concordance cosmology requires at least three extra (possibly dark) cosmological components: one or more dark

Quantum Gravity Effects in Cosmology

Within the geometrodynamic approach to quantum cosmology, we studied the quantum gravity effects in cosmology. The Gibbons-Hawking temperature is corrected by quantum gravity due to spacetime ...

So how to decode such an inverse problem is the challenge GW astronomy provides to us. Currently, the idea is firstly solving the direct problem to construct

Stellar structure and compact objects before 1940: Towards relativistic astrophysics

Einstein’s theory to an astrophysical compact object can be regarded as a milestone in the path eventually leading to the emergence of relativistic astrophysics in the early 1960s. ... established a new relationship between physics and astronomy. When quantum theory decoded the enigma of spectral lines, astrophysics became to grow as a branch of physics. The lively debate about the structure

New observational constraints on f(T) cosmology from radio quasars

Aims and Scopes of the Special Issue: Foundations of Astrophysics and Cosmology

Ironically, we are awkwardly confronted with a largely unknown universe, and yet we adopt the term “precision cosmology ... ”. Indeed, cosmology faces puzzling observations. First, galactic rotation curves, lensing and clustering do not appear to be generated by conventional baryonic matter. Second, it is commonly, although not
