By analyzing the velocity dispersion of the lensing galaxy, researchers estimate that dark matter constitutes about 11% of the mass within the Einstein radius of NGC 6505. This fraction ...

The total mass enclosed within the Einstein radius — the radius of the Einstein ring — has two components: stellar and dark matter components. A dark matter halo is the halo of invisible ...

“Einstein would be very proud ... This bizarre situation sets strict limits on their sizes and masses: For a given radius, a white dwarf can be only so massive, and only so large for a ...

We train the networks to predict the five parameters of the singular isothermal ellipsoid profile: the Einstein radius, the complex ellipticity and the coordinates of the centre of the lens.

Albert Einstein had just published his General Theory ... were compressed into a sufficiently small sphere—a sphere with a radius R, which we now call the Schwarzschild radius.

you’ll see it fall slower and slower towards the Schwarzschild radius, but never actually reach. “Schwarzschild defined the key characteristics of a black hole, something that Einstein hadn ...

The lensing object needs to be smaller than the Einstein radius (in centimetres): Now we compare the relative luminosity of a minihalo at a distance of 0.1 pc (their expected mean separation ...
