This advanced graduate-level path equips learners with the statistical toolkit required to analyze cosmological datasets, focusing on Bayesian inference, MCMC, nested sampling, Fisher matrices, and survey analysis. It progresses from foundational probability and statistics through likelihood construction and practical computational methods, culminating in applications to large-scale structure and cosmic microwave background data.
A graduate-level learning path covering the theory and practice of cosmological N-body simulations, from perturbation theory and initial conditions to simulation codes and halo modeling. Learners will gain the skills to design, run, and analyze structure formation simulations.
A comprehensive graduate-level learning path covering the physics of phase transitions in the early universe, from the foundational cosmology, quantum field theory, and statistical mechanics, through finite-temperature field theory and the effective potential, to the electroweak and QCD transitions, bubble nucleation, and gravitational wave production.
This graduate-level learning path systematically explores modified gravity theories proposed to explain cosmic acceleration, including f(R) gravity, Horndeski theories, massive gravity, and screening mechanisms. It establishes the necessary foundations in general relativity, tensor calculus, differential geometry, and cosmological perturbation theory before delving into theoretical frameworks, observational tests with large-scale structure and CMB, and current constraints.
A systematic graduate-level path covering the quantum foundations of early-universe cosmology: quantum gravity basics, the Wheeler-DeWitt equation, the Hartle-Hawking no-boundary proposal, and quantum fluctuations during inflation including trans-Planckian issues.
A comprehensive graduate-level path covering the theory and application of weak gravitational lensing to probe dark matter and dark energy. It starts with necessary cosmology and general relativity, builds up to shear and convergence, and culminates in modern surveys and results.
This advanced graduate-level learning path covers the physics of Baryon Acoustic Oscillations (BAO) from the sound horizon in the early universe to their use as a standard ruler for probing dark energy. It builds from cosmological perturbation theory and large-scale structure through observational techniques in galaxy surveys and the Lyman-alpha forest, culminating in dark energy constraints.
A comprehensive graduate-level learning path covering the theoretical and observational foundations needed to perform detailed analyses of the cosmic microwave background (CMB). It progresses from cosmological perturbation theory and the physics of the CMB through advanced topics such as polarization, gravitational lensing, foreground removal, and parameter estimation, culminating in a synthesis of current and future experiments like Planck and CMB-S4.
A systematic graduate-level path to mastering the theory of linear perturbations in the universe, covering gauge invariance, scalar/vector/tensor decomposition, the Boltzmann equations, and the evolution of perturbations leading to predictions for the CMB and LSS.
This advanced graduate-level path systematically covers the theoretical foundations of cosmic inflation, its role in solving classic Big Bang problems, and its key observational predictions. It progresses from the horizon and flatness problems through the dynamics of the inflaton field, slow-roll inflation, the generation of primordial perturbations, and concludes with tensor modes and reheating.
