François Mernier - IRAP Hot, X-ray emitting atmospheres permeating the large gravitational well of galaxy clusters are rich in heavy elements (N, O, Si, Fe, etc.). Following Carl Sagan's famous quote "We are made of star-stuff", these metals must have been synthesised by stars and supernovae within stellar populations of cluster galaxies, before being ejected […]
Sebastien Renaux-Petel - IAP, Paris According to the paradigm of cosmological inflation, all the structures of the universe result from quantum fluctuations that were stretched to cosmological scales during a brief phase of accelerated expansion of the universe more than 13 billion years ago. In this seminar, I will describe how gravitational-wave astronomy can revolutionize […]

Baptiste Chide - IRAP On Earth, quantitative analysis of acoustic waves is often used to characterize atmospheric environment. Most notable applications are (i) to characterize various phenomena that are sources of sounds: lightning, atmospheric and fluid circulations, aeroacoustic interactions, etc… (ii) to study the acoustic properties of the propagation medium, the atmosphere itself: speed of […]
Séminaire de Ranjan Gupta (IUCAA, Pune, India) - Salle Jules Verne Abstract : "Artificial Neural Networks (ANN) have been there for more than 4 decades, but only in recent years have gained importance in there usage in areas like face recognition; stock markets; biological applications and others which are more popularly known as AI. The […]

NOTE: UNSUAL TIME AND PLACEINSCRIPTION OBLIGATOIRE / MANDATORY SIGN-UP Alain Riazuelo - IAP Most relativistic effects, whether due to special relativity (aberration, Doppler effect) or general relativity (gravitational blueshift, distortion of light) have been extensively documented for decades. On the other hand, the works on visualization of these and the attempts to render them as […]

Daniela Huppenkothen - U. Amsterdam In data science, the concept of 'hacking' involves ingeniously repurposing solutions from diverse fields to tackle new and complex challenges. My group uses this approach to address fundamental astrophysical questions by drawing on methods and tools originally built for disparate problems in industry or other academic fields. This talk focuses […]
La journée des doctorants 2025 Into the PhD-verse se tiendra le mardi 20 mai dans la salle de Conférences du site Roche ! Toutes les personnes travaillant dans le laboratoire sont invitées à assister à cette journée ! Des stagiaires aux chercheurs/ses, du personnel technique au personnel administratif. Ci-après, le programme de cette journée :
Daily Flaring Activity of the Black Hole at the Center of the Galaxy Farhad Zadeh - Northwestern U. It is clear that an under-luminous supermassive black hole (Sgr A*) with a mass of 4.2 million solar mass lies at the center of the Galaxy. Precise measurements taken at radio and infrared wavelengths over the last two […]
Thomas Haworth - Queen Mary University There is growing evidence that planet-forming disks around young stars can be affected by their wider star forming environment. This environmental impact takes many forms, from chemical inheritance, to gravitational encounters, ``late’’ infall from molecular clouds and external photoevaporation. The latter is my main focus, wherein UV radiation from […]
