Lange Nacht der Forschung 2026: Wir sind dabei!

On 24 April 2026, the twelfth edition of the Lange Nacht der Forschung took place across Austria, attracting around 200 000 visitors from the general public. This year, our Scientific Coordinator, Sonia Foschiatti, together with SFB members Denise Schmutz and Christina Strohmenger, and Noemi Naujoks and Axel Kittenberger from the Computational Science Center, hosted the station “Wie können verkohlte Schriftrollen zerstörungsfrei gelesen werden?” (How can carbonized scrolls be read without destroying them?) in the main building of the University of Vienna. Station link: https://langenachtderforschung.at/station/5679

Guiding visitors through the laboratory experiment, we introduced the magic of virtual unwrapping of carbonized scrolls. We simulated the principles of X-ray Computed Tomography (CT) using visible light, giving both children and adults the chance to see the setup and enjoy funny quizzes and games. Thank you to everyone who made this possible!

Joint Mathematics Meetings (JMM)

At the 2026 Joint Mathematics Meetings (JMM) held in Washington, D.C., Denise Schmutz gave a presentation titled “Asymmetry Conditions for Unique Angular Velocity Reconstruction in Diffraction Tomography” in the AMS Special Session on Tomography Theory and Applications in Honor of Todd Quinto’s 75th Birthday. The talk, based on joint work with Peter Elbau, explored conditions ensuring uniqueness in the reconstruction of rotational motion within the framework of diffraction tomography.

The session celebrated Professor Quinto’s extensive contributions to integral geometry and inverse problems, bringing together colleagues, collaborators, and former students to honor his impact on the field. We are honored to have been part of this special session and grateful for the opportunity to engage with colleagues celebrating Professor Quinto’s lifetime contributions to tomography and inverse problems.

Seeing Inside: Exploring Computed Tomography with Kids

This year, Axel Kittenberger, Denise Schmutz, and Noemi Naujoks once again participated in the Vienna Children’s University, this time with two workshops, each tailored for 20 children aged 7 to 9. Building on last year’s popular topic, we brought back Paula the Sloth to help explain the fascinating world of computed tomography in a playful and accessible way.

The children explored the fundamentals of tomography through a series of interactive stations. These included quizzes, experiments with light and shadow, paint-by-numbers, and exercises demonstrating how mathematics enables us to visualize the inside of objects.

We were excited to see how quickly the children understood complex ideas when given the chance to explore them in a fun way.

SFB Conference “Tomography across the scales”


The SFB Conference “Tomography across the scales” took place from the 16th to the 20th of June at the beautiful Lake Wolfgangsee venue close to Strobl.


We were delighted to welcome many distinguished speakers from renowned international universities. The meeting provided a valuable opportunity to foster interdisciplinary communication and facilitate networking between tomography experts from various disciplines, including astronomy, inverse problems, medicine, biology, and physics.

During the free afternoon, some participants took part in an excursion to the lake Schwarzensee, where they enjoyed the breeze and the view of the lake, while others took the cog railway up Schafberg to enjoy the panorama.

A successful 17th internal SFB meeting

From the 3rd to the 6th of December the 17th internal SFB meeting – winter version – took place at the Obergurgl University Centre in Tyrol, Austria. We were very pleased to welcome as invited speakers Giovanni S. Alberti (University of Genoa, Italy), Bernhard Baumann (Medical University of Innsbruck, Austria), and Sebastian Kamann (Liverpool John Moores University), along with early career researchers from different EU and non-EU institutions. The meeting was a great opportunity to foster interdisciplinary communication, promote networking between researchers and experts in the field of tomography, and enjoy the beautiful landscapes of the Tyrolean Alps. The SFB members had the opportunity to present their work and welcome new members.

We look forward to the first SFB Conference of the project “Tomography across the scales”, which will take place in Strobl, Austria, in 2025. Stay tuned!

7th SFB Member Meeting

Presentations and group activities.

From 9 to 12 September 2024, the 7th SFB member meeting took place in Bad Goisern, Austria, an intense four-day workshop, where PhD students and Postdoctoral Researchers from across our network came together to exchange ideas and discuss cutting-edge topics in science.

The program was enriched by the brilliant presentations of the participants, ranging from theoretical advancements in their field, to communication in science and third mission, to cutting-edge and intriguing topics in science.

Each session sparked lively discussions, driven by the curiosity and insight of the attendees. The setting allowed for a perfect balance of structured talks and informal conversations, fostering a collaborative spirit. Every participant contributed to the dynamic atmosphere, bringing unique perspectives and skills to the table.

Science Meets Kids: The Fascinating World of Computed Tomography

During the 22nd Vienna Children’s University, young students aged 7 to 12 had the opportunity to dive into the fascinating world of computed tomography. Noemi Naujoks, Axel Kittenberger and Denise Schmutz gave an engaging lecture featuring Paula the Sloth as a fun and relatable example for the children.

The lecture was held twice to accommodate the interest, with around 180 children attending both sessions. The interactive format provided the children with not only theoretical knowledge but also practical experiences. Through experiments, a quiz, and special math exercises, the children learned how computed tomography works and the role mathematics plays in it.
