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 misclassified lens has an Einstein radius below the range on which the algorithm is trained. We down-select the most reliable 56 candidates by a joint visual inspection. This final sample is ...

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.

Still at the heart of this ring is a dark shadow, as predicted by Einstein's 1915 theory of gravity ... thus confirming that the radius of a black hole is indeed connected to its mass.

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.
