1. Short News
We would like to congratulate Stamatios I. Stathopoulos for successfully completing his PhD thesis, entitled "Spectral and temporal signatures of leptohadronic radiation models for active galactic nuclei in the multi-messenger era",  at the Physics Department of the University of Athens under the supervision of Prof. Maria Petropoulou. He has recently accepted a postdoctoral position in the Astroparticle Physics group at DESY, Zeuthen, Germany. The Society extends its best wishes to Dr. Stathopoulos for further successes in his professional pursuits.
2. Call for Nominations for EAS Prizes
EAS members are invited to submit nominations for Prizes awarded in 2026 by the EAS. These awards are an international distinction for the work of outstanding scientists. The EAS Council encourages all EAS members to nominate outstanding researchers in above categories.  The strict deadline for nomination is: 31 October 2025 at 23:59:59 CET.  In case of each prize, the nominations can only be made by EAS members and need to be endorsed by 2 additional persons, at least one of them being an EAS member. We encourage nominations of female scientists and individuals from diverse backgrounds and underrepresented countries, in line with our commitment to equity and inclusion. The following prizes will be presented in the coming year during EAS annual meeting in Lausanne: 1) MERAC Prizes for Best Doctoral Thesis - The Prizes will be awarded for the best PhD Theses in three categories: Theoretical Astrophysics, Observational Astrophysics, and New Technologies (Instrumental/Computational/Multi-Messenger) for degrees awarded in the previous 2 years before the call (i.e., from January 2023 onward). 2) Tycho Brahe Medal - The Prize is given in recognition of the exploitation or development of European instruments which led to major discoveries. There are no restrictions to nationality of the candidates nor to the country of origin or residence. 3) Fritz Zwicky Prize - The Prize is given to the high-quality scientists being either at junior, senior, or emeritus faculty levels who have obtained fundamental and outstanding results related to astrophysics and/or cosmology.
3. Greek Diaspora Fellowship Program
We would like to inform our members about the Greek Diaspora Fellowship Program, which offers opportunities to Greek institutions and individual Greek Diaspora Scholars. For more information, please visit this page.
4. ESA Archival Research Visitor Programme
To increase the scientific return from its space science missions, the European Space Agency (ESA) welcomes applications from scientists interested in pursuing research projects based on data publicly available in the ESA Space Science Archives (https://www.cosmos.esa.int/web/esdc). The ESA Archival Research Visitor Programme is open to scientists, at all career levels, affiliated with institutes in ESA Member States and Collaborating States, although we will also consider strong applications from outside those states. Early-career scientists (within 10 years of the PhD) and PhD students are particularly encouraged to apply. We encourage applications from women and minorities. The peer-review evaluation process is anonymised to ensure equal opportunities for all applicants. During their stay, visiting scientists will have access to archives and mission specialists for help with the retrieval, calibration, and analysis of archival data. In principle, all areas of space research covered by ESA science missions can be supported. Residence lasts typically between one and three months, also distributed over multiple visits. Research projects can be carried out at ESAC (Madrid, Spain) and at ESTEC (Noordwijk, Netherlands). To offset the expenses incurred by visitors, ESA covers travel costs from and to the home institution and provides support for lodging expenses and meals.  The deadline for applications is 31 October 2025.   For further details, including areas of research and contact information, please refer to this page.
