On Monday, October 3 at 10.00 we will be welcoming Nicola Franchini (APC) for the gravitation group seminar. The seminar will take place in room 631B, (a zoom link can be found below).
Nicola will talk about the constraints from quasinormal modes on black hole perturbation potentials. 

Constraining modifications of black hole perturbation potentials near the light ring with quasinormal modes

Abstract

Next week we will be welcoming François Larrouturou (DESY Hamburg) for the Gravitation group seminar. 
The seminar will take place in person, in room 371A-Klein (the zoom link can be found below) next Monday, July 11 at 10:00. 

François will give an introduction to: 

Title : Minimalism as guideline to construct new paradigms.

Abstract : 

Jan Harms
Title: Lunar Gravitational-wave Antenna

After recalling the definition of a black hole and its basic properties (mass, angular momentum and area), the seminar will focus on links between black holes and gravitational waves. In particular black hole thermodynamics will be discussed in connection with gravitational wave emission, as well as the so-called black hole information paradox.

Most philosophers of science do philosophy ‘on’ science. By contrast, others do philosophy ‘in’ science (‘PinS’), that is, they use philosophical tools to address scientific problems and to provide scientifically useful proposals. Here, we consider the evidence in favour of a trend of this nature. We proceed in two stages.
