Plebanśki–Demiański à la Ehlers–Harrison: exact rotating and accelerating type I black holes - General Relativity and Gravitation
Recently, it was shown that type D black holes, encompassed in the large Plebanśki–Demiański (PD) family, exhibit a wide class of algebraically general generalizations via the application of Ehlers and Harrison transformations. In this work, we first discuss some mathematical details behind the composition of such transformations, and next, we introduce a qualitative picture of the most general type I generalization of the PD family, dubbed “Enhanced Plebanśki–Demiański” spacetime. We provide the exact form of the solution in the original PD coordinates, obtained via the simultaneous action of an Ehlers and a Harrison transformation on the vacuum PD geometry. In order to make the physics more transparent, we explicitly construct a rotating and accelerating black hole which further has NUT parameter and electric charges, both of them entering, not only the event horizon, but the Rindler horizon as well. This solution is directly obtained in the “physical” coordinates recently proposed by Podolský and Vrátny. Finally, a pedagogical appendix is thoughtfully included, providing readers with a user-friendly step-by-step guide to the Ernst formalism, in an attempt to address and resolve various minor inconsistencies frequently appearing in the relevant literature.

The "Living Reviews" concept featured by the FQxI — Started as unique #OpenAccess journals 20+ years ago at the @maxplanck.de and now published by @springernature.com.

Thanks to its authors and editors, Living Reviews are used hundreds of thousands times each year by researchers and students!

Fundamental constants: from measurement to the universe, a window on gravitation and cosmology - Living Reviews in Relativity
Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would signal a violation of local position invariance and be associated with a violation of the ...

A new review by Josu C. Aurrekoetxea, Katy Clough and Eugene A. Lim shows when cosmology needs numerical relativity, spanning the universe’s history from before the Big Bang through inflation, reheating, phase transitions, and late-time structures.

I'm sad to report that Rainer (Rai) Weiss passed away yesterday at age 92. Rai developed the design for LIGO, he and Kip got it funded, trained countless researchers, and received the 2017 Nobel Prize. Rai always had time for students and treated us as equals. May his memory be a blessing
