Title: The Black Hole Information Paradox revisited
Abstract: I will briefly introduce the black hole information paradox and then move on to discuss soft hair on black holes in quantum electrodynamics and gravity. I will then conclude by explaining how this might help resolve the information paradox and review the steps that will be needed to achieve this goal.

Title: Energy discreteness and gradient flows for harmonic map and Yang-Mills energy functionals
Abstract: The Lojasiewicz-Simon gradient inequality is a generalization, due to Leon Simon (1983), to analytic functionals on Banach manifolds of the finite-dimensional gradient inequality, due to Stanislaw Lojasiewicz (1963), for analytic functions on Euclidean space. We shall discuss several recent generalizations of the Lojasiewicz-Simon gradient inequality and a selection of their applications, such as global existence and convergence of Yang-Mills gradient flow over four-dimensional manifolds and discreteness of the energy spectra for harmonic maps from Riemann surfaces into analytic Riemannian manifolds and Yang-Mills connections over four-dimensional manifolds.

She has over 15 years’ experience working in PR and communications and has wide-ranging experience of providing strategic communications support to organisations. Learn more about the competition and submit an entry 👉dias.ie/reachforthesta… #DIASdiscovers #astrophotography
Meet the Judges of our "Reach for the Stars" Astrophotography competition! @MartinaPQuinn is the Founder & Managing Director of @helloalicepr.
Want to learn more about what's happening on Mars? Check out our public lecture from November delivered Dr John Clinton and titled MarsQuakes! (5/5) youtu.be/_Lp0oLJ8Ahs
And then this Thursday @NASAMars Perseverance rover reaches Mars, which will try to land in a near equatorial crater called Jezero. Here you can see a possible route around the crater. (4/5)
Last Wednesday, the day the UAE revealed their first image of Mars, China's National Space Administration's Tianwen-1 arrived at Mars. This carries a rover which will be despatched to the surface in the coming months. (3/5) bbc.com/news/science-e…
First up is the @uaespaceagency's Hope mission entered orbit this day last week. It is the first inter-planetary mission by the UAE, and will stay in a wide orbit for one Martian year or two earth years to study climate and weather. (2/5)
It's a busy month over at our planetary neighbour Mars. Three missions headed there have or will enter orbit this month. Why so many at one time? They were timed to launch when the distance between the Earth and Mars was relatively short. (1/5)

Looking for some #MondayMotivation? We are delighted to share this short video by @CClearych who is the O'Donovan Scholar at the School of Celtic Studies. Here she describes the amazing inputs of Eleanor Knott MRIA. youtu.be/Zfvw0KZbFTk @SCSLibrary @RIAdawson
