Dear All,

The coming week we?ll have the following seminar

When: Thursday 20th October 2022 - 16h00

Where: Aula Conversi - Marconi Building

Speaker: Gianfranco Bertone (GRAPPA, Amsterdam)

Title: Dark matter, black holes, and gravitational waves

Abstract: I will start with an overview of the status of dark matter
searches and of the prospects for uncovering its nature in the next
decade. I will then focus on the interplay between dark matter, black
holes, and gravitational waves, and discuss the prospects for
characterizing and identifying dark matter using gravitational waves,
covering a wide range of candidates and signals. Finally, I will
present some new results on the detectability of dark matter
overdensities around black holes in binary systems, and argue that
future interferometers may enable precision studies of the dark matter
distribution and particle properties.

 Cortini: Swetha Bhagwat (Birmingham U.) "The importance of using amplitudes

Message-ID: <CADjeKwAMDq79_ih=_DUOk96kLJnXiX8sX=j4p7_LMktXOVSSFg@mail.gmail.com>

Dear everyone,

Next week we will have Swetha Bhagwat visiting and giving a seminar. Please
find information below (note the unusual time and location). I also remind
you Gianfranco Bertone's INFN theory seminar tomorrow:
https://agenda.infn.it/event/32753/

%%%%%
*Speaker: *Swetha Bhagwat (Birmingham U.)
*Title: *The importance of using amplitudes and phases in ringdown to test
GR

*Date:*  Wednesday, October 26th at 1pm CEST
*Location:* Cortini Hall (Fermi building)


*Abstract:  *
When two black holes merge to form a remnant black hole, they emit a signal
called ringdown. Ringdown comprises of the excitation of characteristic
modes of remnant black hole a.k.a, Quasinormal modes (QNM) and serves as a
powerful probe to test our understanding of strong field gravity around
black holes. These tests have traditionally relied on extracting QNM
frequencies and damping times. While this is powerful, the excitation
amplitudes of QNM also carry vital information about strong-field gravity
dynamics. I will specifically talk about two tests that we proposed
recently on how we could use amplitude and phase information -- the
amplitude-ratio phase test and the merger ringdown test.

Best,
Paolo
