This advanced graduate-level path equips learners with the skills to analyze cosmic microwave background (CMB) data, covering map-making, power spectrum estimation, component separation, foreground cleaning, noise analysis, and systematics mitigation. It builds from foundational cosmology and signal processing through to advanced analysis techniques, with practical Python applications.
This learning path explores the philosophical questions raised by modern cosmology, including the fine-tuning of the universe, the anthropic principle, multiverse theories, and the nature of scientific inquiry. It begins with the basics of cosmology and scientific method, then examines observational limits and key philosophical debates, culminating in an assessment of scientific realism and the multiverse hypothesis.
This learning path equips university students with the knowledge and skills to communicate cosmological discoveries effectively to diverse public audiences. It covers core cosmology concepts, common misconceptions, visualization techniques, educational resources, and practical engagement strategies including media interviews.
A graduate-level learning path that builds from foundational cosmology and general relativity through advanced topics in dark matter, modified gravity, and particle physics, culminating in the synthesis of cosmological probes with fundamental physics, including string theory and laboratory tests.
This advanced graduate-level path systematically explores the origin and detection of cosmic magnetic fields, from fundamental plasma physics and magnetohydrodynamics to cosmological magnetogenesis and observational probes. Learners will develop a deep understanding of how primordial magnetic fields are generated, evolve, and leave observable imprints on the cosmic microwave background and large-scale structure.
A graduate-level learning path covering the role of neutrinos in cosmology, from the physics of neutrino decoupling and relic densities to their effects on the cosmic microwave background and large-scale structure, and how cosmological observations constrain the sum of neutrino masses.
This path equips graduate students in cosmology with the theoretical and data-analysis skills needed to combine independent cosmological probes—Type Ia supernovae, BAO, weak lensing, RSD, galaxy clusters, and CMB—to constrain dark energy. It covers the underlying physics, probe-specific observables, systematics, and the statistical methods for joint analysis, culminating in a synthesis and forward look to future surveys.
This advanced graduate-level path equips learners with the knowledge and skills to design, run, and interpret cosmological hydrodynamical simulations of galaxy formation. It covers the underlying physics from dark matter and structure formation to baryonic processes like cooling, star formation, and feedback, and culminates in understanding and using major simulation codes and models.
A graduate-level learning path covering deviations from Gaussian initial conditions in cosmology. It starts with the essential physics of inflationary perturbations and progresses through the formalism of higher-order correlation functions, specific non-Gaussian shapes, their inflationary origins, and observational constraints from the CMB and large-scale structure.
This advanced graduate-level path systematically develops the physics and observational techniques needed to understand the cosmological 21-cm signal from neutral hydrogen. It covers the atomic physics of the hyperfine transition, the spin temperature and radiative transfer, the power spectrum as a statistical probe, the astrophysics of the Dark Ages and Epoch of Reionization, and the practical challenges of detection including foreground removal and upcoming radio arrays like SKA.
