๐ CENTRA Outreach Activity ๐
Sept 14 marks 10 years since the 1st detection of Gravitational Waves @ligo.org!
Join us at Pavilhรฃo do Conhecimento in Lisbon for demos & a public talk by Prof. Vรญtor Cardoso. Events also in Aveiro & Porto.

Are black holes fuzzy or bald? This question is intimately connected with the greatest puzzle in modern physics: How can general relativity be merged with quantum theory?
Gravitational waves, like those recorded at the Virgo interferometer near Pisa, Italy, are helping scientists test if individual black holes have unique qualities.

๐ Welcome GW231123 ๐
The most massive black hole binary ever detected by @ligo.org / Virgo / KAGRA! ๐ฅ
The remnant #BlackHole has approximately 260 solar masses! CENTRA researchers are studying the origin of such an extreme event! Stay tuned!

๐ Black hole in a room ๐
New work by Oshita, Berti & Cardoso shows how black holes "ring" like instruments in a roomโechoes and all. Their study reveals how destabilized modes improve ringdown models. Now in PRL @apsphysics.bsky.social!

๐ Galaxies Do Not Affect Black Hole Spectroscopy ๐
When a black hole is disturbed, it "rings" like a bell. A new study in #PRL @apsphysics.bsky.social, shows that this process is not significantly altered when the black hole is in the heart of a galaxy.
