Observational Cosmology
The study of the origin, evolution, and structure of our Universe.
Research methods in observational cosmology:
Gravitational lensing
Short description of gravitational lensing and cosmology.
21cm intensity mapping
Trace HI structure in the Universe to measure matter power spectrum and baryon acoustic oscillations
Galaxy & Quasar Clustering
Standard ruler and growth of structures
Lyman-Alpha Forest
Probing the intergalactic medium
Spectroscopic Surveys
Probing the 3D map of galaxies and quasars in the Universe
Cosmological Simulations
Synthetic universes that mimic the observed large-scale structures
Extragalactic Distance Scale
Measuring distances and the Hubble constant using standard candles
