thinking at the horizon.
I am an astrophysicist who has spent decades at the frontier of discovery and international scientific collaboration. Today, I bring that experience to selected engagements in science, international cooperation and public dialogue.
For most of human history, a black hole could only be inferred — never seen.
In 2019, we changed that. Six and a half billion solar masses. Fifty-five million light years away from us. An image that required the resolution to photograph a donut on the moon.
With my team and international partners, we turned a scientific vision into a global scientific enterprise. We advanced Very Long Baseline Interferometry by linking radio telescopes across the globe into a single Earth-sized instrument. That made the first image of a black hole possible.
As emeritus, I continue my research and take on a select number of engagements where experience and perspective can make a difference. Curiosity, a sense of responsibility, and a collaborative spirit continue to shape how I work.
science at scale.
I study distant galaxies and the role of supermassive black holes — how magnetic fields shape their environments, and how relativistic jets form in their vicinity.
For over two decades, my group and international partners advanced the capabilities of global radio interferometry until imaging a black hole became possible. Today, my ERC Advanced Grant M2FINDERS continues that pursuit at the jet-launching region of M87’s supermassive black hole.
Discovery becomes lasting value when scientific insight connects with technology, infrastructure, and the people who build both.
The first image of a black hole required more than a bold idea. It required decades of building: connecting telescopes across continents, advancing technology, and developing the methods that turned vast amounts of data into trustworthy images. Much of that groundwork was laid in Bonn.
Scientific experience brings responsibility beyond one’s own research. Today, I engage where scientific independence, public trust, and the long-term resilience of research systems are at stake — particularly in international and transatlantic contexts.
I have spent decades at the intersection of discovery and responsibility — and I believe scientists who have been there have an obligation to speak.
I contribute through lectures, interviews, and long-form conversations on science, research policy, and international cooperation.

For advisory, mentoring, supervision, or invited lectures: azensus@antonzensus.de
I work with institutions and leaders where long-term perspective matters more than quick answers — helping to hold complexity, sharpen questions, and think through what responsibility requires.
My work includes science strategy, research governance, and the long-term development of research organisations.
I founded the International Max Planck Research School for Astronomy and Astrophysics, now widely recognised as a model for international doctoral education.
Almost every European researcher active in our field today spent formative time in the Bonn group. Many now lead their own groups and train their own students.
That investment in people continues in a different register today — in conversations with individuals navigating roles that carry weight beyond themselves, collegial, reflective, and grounded in shared experience.
My approach in this area is informed by certified training in systemic coaching and supervision.
