The Beijing Physics, Astrophysics, and Cosmology (B-PAC) workshop was held at the Kavli Institute for Astronomy and Astrophysics at Peking University (KIAA) on June 12, 2026, bringing together researchers from across Beijing working in physics, astrophysics, and cosmology. This gathering marked the second edition of the B-PAC series, following the inaugural meeting hosted at the International Centre for Theoretical Physics – Asia Pacific (ICTP-AP) earlier this year.
The half-day workshop included 20 participants, with postdoctoral researchers and graduate students from Peking University, Tsinghua University, ICTP-AP, the National Astronomical Observatories (NAOC), and The Chinese University of Hong Kong, as well as other institutions in the Beijing area.
The workshop opened at noon with brief remarks highlighting the goal of strengthening scientific connections within the local community and providing a platform for early-career researchers to interact, exchange ideas, and explore potential collaborations. The program featured two invited talks: Boris Kalita (KIAA) on The Hierarchy of Star Formation in the Early Universe, and Álvaro Segovia Otero (Department of Astronomy, Tsinghua University) on Connecting Galactic Disc Assembly to Its Star Formation Properties Across Cosmic Time.
Following the talks, participants engaged in an open discussion session covering a wide range of topics in astrophysics, including star formation, cosmology, dark matter haloes, numerical simulations of galaxies, and recent observations from the James Webb Space Telescope, among others. The discussion also touched on opportunities for collaboration between different research groups and the broader development of a Beijing-based research network. The informal format encouraged active participation and fostered new scientific connections among attendees.
The workshop (https://indico.ictp-ap.ucas.ac.cn/event/6/) is organized by Andrew Miller, faculty member of the ICTP-AP and Verónica Vázquez Aceves, postdoc at KIAA.
