On August 18, 2025, Dr. Evanthia Hatziminaoglou from the European Southern Observatory (ESO) and the Instituto de Astrofísica de Canarias (IAC) delivered an insightful invited talk at the University of Latvia. The presentation provided a comprehensive overview of cutting-edge astronomical research and advancements, focusing on ESO's contributions, the ALMA telescope, the Atacama Large Aperture Submillimetre Telescope (AtLAST), and the study of quasars. Dr. Hatziminaoglou highlighted ESO's role as the leading intergovernmental astronomy organization, encompassing 16 member states and strategic partnerships with Chile and Australia. The talk showcased ESO's groundbreaking facilities, including the Very Large Telescope (VLT) at Paranal and the upcoming Extremely Large Telescope (ELT), set to be the largest optical/infrared telescope in the world. The presentation also delved into ALMA's capabilities, emphasizing its precision in resolving small details and its ongoing upgrades to enhance sensitivity. Dr. Hatziminaoglou discussed the AtLAST concept, a next-generation 50-meter single-dish observatory powered by renewable energy, designed to bridge gaps in angular scales, sensitivity, and mapping speed in submillimeter astronomy. A significant portion of the talk focused on the study of quasars, exploring their environments, star formation rates, and the triggers of extreme star formation in quasar hosts. Dr. Hatziminaoglou shared findings on multiplicities around SDSS quasars, revealing how submillimeter counterparts and redshift influence star formation rates and environments. In addition to the scientific presentation, there was a lively discussion on potential collaboration between the University of Latvia, Riga Technical University, and Ventspils University of Applied Sciences. The discussion emphasized creating pathways for Latvian researchers and students to engage with ESO and ALMA facilities, opening new opportunities for joint projects, training, and integration into international astronomy networks. This engaging presentation underscored the synergy between ESO's facilities, ALMA, and AtLAST, paving the way for future discoveries in astronomy. Dr. Hatziminaoglou's talk was an inspiring showcase of the collaborative efforts driving innovation in the field and inspiring the next generation of astronomers.
