Title: Einstein–Maxwell–Anti-de-Sitter solitons and black holes
Speaker: Eugen Radu (Aveiro University)
Abstract: We consider a new class of solutions in Einstein-Maxwell theory with a negative cosmological constant, that approach asymptotically a globally Anti-de-Sitter (AdS) background in four spacetime dimensions. There are no analogue objects to these solutions in asymptotically flat spacetime and their existence can be traced back to the “box”-like behaviour of the AdS spacetime. Both solitons and black holes are discussed. In the latter case, we report on static solutions that have no continuous spatial symmetries. These black holes have a smooth, topologically spherical horizon, but without isometries.
Time: Thursday 8th December 2016, 2.00pm.
Place: Lecture Room, School of Theoretical Physics, DIAS, 10 Burlington Road, Dublin 4.

Big thank you to @MartinaPQuinn of @helloalicepr for moderating the discussion, and of course to our panel @NeasaMcG @CormacORafferty and @laoneill111
@CormacORafferty "to cut yourself off from fundamental research means you could miss out on some of the biggest ideas"
@laoneill "it's our job as researchers to keep reminding governments how important basic research is" "For Dev basic research being carried out in Ireland was a badge of pride"
@NeasaMcG Schrödinger's work in causality was not well received by the religious authorities at the time At the same time DIAS did have Catholic priests working on research projects in the early days, so there was not the conflict you might think between science and religion
@laoneill111 Schrödinger was very popular in social circles in Dublin, a bit of a renaissance man
@CormacORafferty Schrödinger was gifted at explaining difficult concepts
@CormacORafferty on how unsuccessful work, in Schrödinger's case, unified field theory, is just as important part of science. And no one has managed to crack it yet! And not forgetting the cat
@laoneill111 how Schrödinger's book inspired scientists to change fields and result in the finding of the double helix.
@NeasaMcG explaining how DIAS came about and how Schrödinger was attracted to Ireland #DIASdiscovers
