We are at a pivotal moment in cosmology. An unprecedented influx of observational data—from the tomography of black holes and the detection of gravitational waves to the precision mapping of the cosmic microwave background (CMB) and large-scale structure (LSS)—has placed us in a "gold mine" of discovery. Moreover, future surveys such as Euclid and LiteBird will further increase the challenge of analysing cosmological data.
However, this wealth of data has also sharpened our most fundamental questions. The nature of dark matter and dark energy remains elusive, cosmological tensions (such as the Hubble constant discrepancy) persist, and key details of the primordial universe, including inflation and baryogenesis, are still unresolved.
To unravel the fundamental physics underlying our universe, this conference aims to build a collaborative bridge between the three foundational pillars of modern research:
- Theoretical Modeling: Developing the fundamental theories of inflation, dark matter, and modified gravity.
- High-Performance Computing (HPC): Running sophisticated simulations (e.g., numerical relativity and large-scale structure formation) that link theory to reality.
- Advanced Data Analysis: Employing cutting-edge AI/ML and astro-statistical techniques to extract meaningful insights from massive and complex datasets.
"Big Bang Big Stars Big Computer" will bring together leading theorists, computational scientists, and observational astronomers. The conference will explore the synergistic relationship between these disciplines, addressing how fundamental theories guide simulations, how HPC provides the crucial link between theory and observation, and how AI-driven data analysis unlocks discoveries hidden within complex datasets.
We warmly welcome abstract submissions for talks and posters across all areas of astrophysics and cosmology. You do not need to work in HPC or computational astrophysics to participate — we actively encourage contributions from researchers working in observational, theoretical, and data-driven astrophysics and cosmology. This conference is designed to build bridges between our communities, and broad astrophysical contributions are essential to that mission.
