Discrete analog of the Jacobi set for vector fields

A. N. Adilkhanov, A. V. Pavlov, I. A. Taimanov

The Jacobi set is a useful descriptor of mutual behavior of functions defined on a common domain. We introduce the piecewise linear Jacobi set for general vector fields on simplici…

Understanding the "Feeble Giant" Crater II with tidally stretched Wave Dark Matter

A. Pozo, T. Broadhurst, R. Emami +1

The unusually large "dwarf" galaxy Crater II, with its small velocity dispersion, km/s, defies expectations that low mass galaxies should be small and dense. We combine…

Finding quadruply imaged quasars with machine learning. I. Methods

A. Akhazhanov, A. More, A. Amini +68

Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They are very rare in the sky -- only a few tens are known to date -- and yet they provide unique inform…

On the duality of Schwarzschild-de Sitter spacetime and moving mirror

Diego Fernández-Silvestre, Joshua Foo, Michael R. R. Good

The Schwarzschild-de Sitter (SdS) metric is the simplest spacetime solution in general relativity with both a black hole event horizon and a cosmological event horizon. Since the S…

Finite thermal particle creation of Casimir light

Michael R. R. Good, Eric V Linder, Frank Wilczek

A new solution for an analytic spectrum of particle creation by an accelerating mirror (dynamical Casimir effect) is given. It is the first model to simultaneously radiate thermall…

Möbius Mirrors

Michael R. R. Good, Eric V. Linder

An accelerating boundary (mirror) acts as a horizon and black hole analog, radiating energy with some particle spectrum. We demonstrate that a Möbius transformation on the null coo…
