In this article we find a four-dimensional metric for a large black hole immersed in dark matter. Specifically, we look for and find a static spherically symmetric black hole solution to the Einstein equations which gives, in the Newtonian limit, the rotation curves of galaxies, including the flat region and the Baryonic Tully-Fisher relation, and which has a regular horizon. We obtain as well the energy-momentum tensor of the dark matter sourcing this space-time and it turns, in special, to…

Solar system, astrophysics, and cosmology from the derivative expansion
In this paper we show how the solar system, the galactic, and the cosmological scales, are accommodated in a single framework, namely, in the derivative expansion framework. We construct a locally


Galactic rotation curves in conformal gravity
We review some recent work by Mannheim and O'Brien on the systematics of galactic rotation curves in the conformal gravity theory. In this work the conformal theory was applied to a comprehensive,
Black Strings Ending on Horizons
We construct an approximate static gravitational solution of the Einstein equations, with negative cosmological constant, describing a test black string stretching from the boundary of the
The baryonic Tully-Fisher relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in ΛCDM and of
Anisotropic stars as ultracompact objects in general relativity
Anisotropic stresses are ubiquitous in nature, but their modeling in General Relativity is poorly understood and frame dependent. We introduce the first study on the dynamical properties of
The Large Scale Structure of Space-Time
The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.
Rotation and Mass in the Milky Way and Spiral Galaxies
[PASJ Review Paper] Rotation curves are the basic tool for deriving the distribution of mass in spiral galaxies. In this review, we describe various methods to measure rotation curves in the Milky
Universal Properties of Centripetal Accelerations in Spiral Galaxies
In a recent paper McGaugh, Lelli, and Schombert (Phys. Rev. Lett. \textbf{117}, 201101 (2016)) showed that in a plot of the observed centripetal accelerations against those predicted by the Newtonian
Dark halos of M 31 and the Milky Way
Grand rotation curves (GRC) within ∼ 400 kpc of M31 and the Milky Way were constructed by combining disk rotation velocities and radial velocities of satellite galaxies and globular clusters. The GRC
The Baryonic Tully-Fisher Relation.
The Tully-Fisher relation appears fundamentally to be a relation between rotation velocity and total baryonic mass of the form Md~V4c.
