CRC 1245
Nuclei: From Fundamental Interactions to Structure and Stars

General Information

CRC 1245 “Nuclei: From Fundamental Interactions to Structure and Stars” investigates the strong and electroweak interaction physics from nuclei to stars. The physics of nucleonic matter ranges from universal properties at low densities to the densest matter we know to exist in neutron stars. Chiral effective field theory provides a link between nuclear structure and matter in stars with the underlying theory of the strong interaction. The pioneering work in this CRC, accessing the medium-mass region of nuclei, provides the basis for the ultimate goal of a consistent description of nuclear structure across the nuclear chart into the heavy-mass region of nuclei and for matter in stars. Additionally, strong and electroweak processes are key to understanding the chemical contribution from supernovae and neutron star mergers to the Universe, and will provide systematic uncertainties for nuclear matrix elements required to test fundamental symmetries. The reach of CRC 1245 thus extends well beyond nuclear physics with a demonstrated impact on neutrino physics, astroparticle physics, and astrophysics.



Women’s Weeks are annual events of the SFB 1245 which aim at actively discussing gender equality and bringing it to the attention to everyone within the SFB in various different ways. These special weeks come along with a special colloquium. For the latter, internationally renowned female researchers are invited. For example, in 2017, the renowned book author, Sharon Bertsch McGrayne, gave a physics colloquium on “Bayes’ rule and Laplace’s big data” within this week. In 2020, the Women’s Week featured a colloquium on “A new perspective on the Universe in the era of multi-messenger astronomy” by the winner of the New Horizons in Physics Prize, Prof. Samaya Nissanke. The colloquium is always combined with networking events among all female SFB members and the invited speaker. Important integrated pillars of each Women’s Week are topical workshops, such as the so-called “Challenge Club” by Christiane Zerfaß in 2018 and a workshop on gender awareness and unconscious bias by Deborah Ruggieri in 2020.

Best Practice

Video for the International Day of Women and Girls in Science

The CRC 1245 created a video for the international day of women and girls in science. In the video Prof. Dr. Verena Spatz (Jun.-Professorin für Physikdidaktik), Sabrina Huth (Kernphysik Forscherin) und Prof. Dr. Almudena Arcones (Professorin für Astrophysik) explain the network's research for young students.

The mentoring program for female Master students of SFB 1245 is meant to attract female students to the SFB 1245. On the basis of assistant (“HiWi”) contracts, it allows the principal investigators of the SFB to hire female students in the Master program for a three-month project within the fields of research covered by the SFB 1245. In addition to the supervisor, the student is in contact with a dedicated mentor from the SFB. This ensures that the can gain valuable insights into the SFB and its research program. Moreover, the program provides financial support for the participation of the student in workshops and conferences, which helps to further foster their integration into the SFB.

One of the most effective measures for supporting women in advancing their careers in academia is coaching. The CRC 1245 has been offering coaching units for their female researchers from the beginning and makes therefore full use of the gender equality funds provided by the DFG.

For better being able to recruit excellent foreign female researchers at the junior researchers level, it is desirable to educate them in the field of the CRC already at the Master level at TU Darmstadt. However, since a two-year long Master study may be financially inhibitive for many excellent female students from foreign countries, TU Darmstadt and its Institute for Nuclear Physics have established the “Ira Rischowski” program which offers an annual awarding of two-years stipends for exceptionally talented female Master students from abroad for conducting their Master studies in the fields of nuclear physics, nuclear astrophysics, or accelerator science at TU Darmstadt. Graduates from this program will represent excellent candidates for positions within the CRC in the future.
