Black holes at different flavours - WE - Heraeus - 2026 EAS Workshop for Early Career Research in Astronomy

21 Sept 2026, 08:55 → 25 Sept 2026, 19:05 Europe/Warsaw

HERA 2026 ● 21-25 September 2026 ● CAMK PAN WARSAW

Black holes at different flavours

WE-Heraeus-eas workshop for early career researchers in astronomy

 

PRACTICAL INFORMATION / VENUE / ACCOMMODATION ►

 

HERA 2026 – Black Holes at Different Flavours brings together early career researchers and leading experts to explore the rich and evolving landscape of black hole physics. From theoretical foundations to cutting-edge observations, the workshop creates a space for deep discussion, fresh ideas, and new collaborations.

With speakers including Roger Blandford, Monika Mościbrodzka, Vladimir Karas, Samaya Nissanke, and Marek Abramowicz, participants will have a unique opportunity to engage directly with researchers who shape our understanding of accretion physics, relativistic jets, gravitational waves, and strong-gravity astrophysics.

Join us for a week of scientific intensity, open discussion, and inspiration — where the next generation of black hole research begins. 

 

Note: Up to forty (40) successful applicants will have all stay-related costs, including lodging and living costs, fully covered.
