Static Charged Polytropic Spheres with a Cosmological Constant: Physical Acceptability and Trapped Orbits
Alex Stornelli, Anish Agashe
We consider static charged fluid spheres with a cosmological constant. We assume a polytropic equation of state, , and a power law charge distribution, $q\propto r^n…
On the Effects of Non-metricity in an Averaged Universe
Anish Agashe, Sai Madhav Modumudi
In the covariant averaging scheme of macroscopic gravity, the process of averaging breaks the metricity of geometry. We reinterpret the back-reaction within macroscopic gravity in…
The Tolman VII Space-time in the Presence of a Charge and a Cosmological Constant
James Ripple, Anish Agashe
The Tolman VII space-time is one of the few physically acceptable exact solutions in general relativity. In this paper, we derive a generalised Tolman VII solution which includes a…
Schrödinger Connections: From Mathematical Foundations Towards Yano-Schrödinger Cosmology
Lehel Csillag, Anish Agashe, Damianos Iosifidis
Schrödinger connections are a special class of affine connections, which despite being metric incompatible, preserve length of vectors under autoparallel transport. In the present…
Lagrangian Formulation of the Raychaudhuri Equation in Non-Riemannian Geometry
Anish Agashe
The Raychaudhuri equation for a congruence of curves in a general non-Riemannian geometry is derived. A formal connection is established between the expansion scalar and the cross-…
Spherical and Plane Symmetric Solutions in Macroscopic Gravity
Anish Agashe, Mustapha Ishak
The theory of macroscopic gravity provides a formalism to average the Einstein field equations from small scales to largest scales in space-time. It is well known that averaging is…
Kinematics in Metric-Affine Geometry
Anish Agashe
In a given geometry, the kinematics of a congruence of curves is described by a set of three quantities called expansion, rotation, and shear. The equations governing the evolution…
An Almost-FLRW Universe as the Averaged Geometry in Macroscopic Gravity
Anish Agashe, Mustapha Ishak
It is well-known that spacetime averaging is an operation that does not commute with building the Einstein tensor. In the framework of Macroscopic gravity (MG), a covariant averagi…
Separating the Intrinsic Alignment Signal and the Lensing Signal using Self-Calibration in Photo-z Surveys with KiDS450 and KV450 Data
Ji Yao, Eske M. Pedersen, Mustapha Ishak +4
To reach the full potential for the next generation of weak lensing surveys, it is necessary to mitigate the contamination of intrinsic alignments (IA) of galaxies in the observed…
