Astrophysics is Booming

The Nobel Prizes of the past decade are shining proof of this. Today, we stand on the threshold of fundamentally new insights into the nature of the universe. Astrophysics encompasses all facets of modern technology and serves as a driver of economic development. The establishment of a German Center for Astrophysics (DZA) with international significance is a crucial catalyst for future-oriented change in Lusatia.

The Idea of the DZA

This video summarizes the concept behind the German Center for Astrophysics and its mission. What motivates the researchers, and why do the two profound questions of humanity—“Where do we come from?” and “Where are we going?”— drive both fascination and research? We’ve condensed the answers into just 195 seconds. Enjoy!

Astrophysics

Research at the Edge of What Is Possible

New observatories receive various 'messengers' from the universe, such as light signals across different wavelengths. Today, it's not only optical telescopes providing us with insights into the cosmos; in addition to our 'eyes', we now have 'ears' for astronomy. Astrophysicists measure cosmic radiation, neutrinos, and even gravitational waves—the echoes of spectacular events deep within the universe. To do this, researchers require highly sensitive and precise measurement techniques, as well as an optimal environment free from disturbances, such as the one found in Lusatia.

A world-class astrophysical institute is emerging that will contribute to international large-scale research infrastructures, significantly strengthening Germany's position as a leading scientific hub in global competition. Initially, we will focus on radio astronomy and the study of the dynamic universe, as well as the investigation of compact astronomical objects using gravitational waves.

Data Science

Foundation and Building Block of Modern Research

Data streams from various astronomical observatories around the world will converge in Saxony. These data volumes are several times the size of today’s Internet and demand new technologies. We are managing this enormous flood of data through green computing, accelerating digitalization and ensuring a more resource-efficient, modern society.

Scientific calculations are crucial in astrophysics for improving our understanding of the universe and testing theoretical models. They are therefore a key component of the DZA's Data Science research pillar. This importance is further underscored by the Nobel Prize in Physics in 2024, which awarded two pioneers of machine learning. Their groundbreaking work will have a significant impact on the DZA’s scientific pillars: Astrophysics, Instrument Development, and Scientific Calculations.

Even during the construction phase of the DZA, the foundation for future breakthroughs is being laid, particularly in algorithms for fast, green online and offline computing, as well as in smart sensors. We are beginning to build a bridge to connect to radio astronomy and the future Square Kilometre Array Observatory (SKAO).

Technology

In the Engine Room of Progress

Progress in the development of new technologies drives scientific breakthroughs, innovations, and collaborations with industrial partners. It enables the German astrophysics community to participate in national and international activities, taking a pioneering role.

During the construction phase of the DZA, we will establish the strategic and technical foundations for its involvement in cutting-edge research, equipping the laboratories with optical, mechanical, and electrical instruments. We also plan to install vacuum and cryogenic technologies.

We are building a Center for Technology that will focus on developing new semiconductor sensors, silicon optics, and control techniques for observatories, among other innovations.

Exploring the Underground

Research in the Treasure of Lusatia

Beneath the surface of Lusatia lies a true scientific treasure: seismic quiet. Where seismic waves would normally pass through the Earth’s surface, Lusatia’s unique geology offers ideal conditions for developing measurement and production technologies, as well as novel gravitational wave detectors.

We are exploring this treasure through surface-level measurements and collecting data from deep within the ground. Initial test drills have already been carried out in the Sorbian community of Ralbitz-Rosenthal in the Cunnewitz district, with further drilling planned across Lusatia.

Accompanying and Shaping Change

Transformation Research

The DZA recognizes its responsibility to play a central role in the structural transformation and sustainable development of Lusatia. As such, the field of transformational research will scientifically support the establishment of the DZA in the region, assist in shaping the transformative change, and provide recommendations for structural and scientific policies.

The department collaborates with experts in regional transformation who were instrumental in initiating and shaping the concept of transformational research at the DZA. This network includes the Technical University of Dresden (TUD), the University of Applied Sciences Zittau/Görlitz (HSZG), the Leibniz Institute of Ecological Urban and Regional Development (IOER), the Institute of Saxon History and Ethnology (ISGV), and the Sorbian Institute (SI).

Research in the Deep

Low Seismic Lab

We are constructing an underground research laboratory, located 200 meters below the surface in the granite bedrock. Surrounding the lab will be a seismic cage, covering a square kilometer, designed to detect and eliminate disturbances. This will create a place of absolute silence: the ‘seismic zero.’ The Low Seismic Lab will serve as a research and development facility for the creation of instruments used in gravitational wave astronomy.

Listening to the universe and improving observation

Einstein Telescope and SKAO

Over and beyond the DZA we investigate the suitability of Lusatia as a location for the Einstein Telescope, a European gravitational waves observatory below the surface that is in progress. We believe Lusatia to be an especially fitting place due to her location in the center of Europe, her strong universitary and industrial surroundings and the unique seismic silence in her granite stock.

Apart from that we are participating with two telescopes at the Square Kilometre Array Observatory in Botswana and South Africa in a new super telescope.

Low Seismic Lab

Underground laboratory in the treasure of Lusatia

With the Low Seismic Lab (LSL), an underground laboratory is being created in Lusatia - in absolute silence. Seismic disturbances and noises of all kinds are to be kept out of the laboratory in the granite dome at a depth of 200 metres. This will allow extremely precise measurement technology and new technologies to be developed and tested under extreme conditions. The astronomy of tomorrow is developing its innovations in Lusatia.
