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 […]

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 […]

Rolf Bühler As urban areas continue to expand, the excessive and misdirected use of artificial lighting is brightening the natural night-time environment. The consequences of this light pollution are far-reaching and affect human health, wildlife,energy consumption, and our ability to observe the night sky. In this talk, I will provide an overview of this topic. I will then present new software that simulates diffuse light pollution due to city skyglow, as well as the one produced directly by lamps on the ground. These simulations are based on satellite measurements of night-time radiance.Contrary to the global trend, I will […]

Daniel Price (Monash U.) Our solar system makes it seem like the planets were formed in a nice, ordered disc. But dig a little deeper and there are hints that things are not quite as neat as they seem — spins do not align, dust appears to have been violently melted and the planetesimal disc […]
