ABSTRACT
|
The need for precise and accurate measurements of cosmological parameters is increasing more than ever recently. In particular the Hubble tension has become one of the hottest issues in both observational and theoretical cosmology today. Measuring a distance to galaxies is a fundamental step to cosmography. It is simple in principle, but not in practice. The tip of the red giant branch (TRGB) is a very efficient and precise standard candle for measuring the distances to resolved galaxies. The TRGB is a powerful tool, playing as a rising star in the era of precision cosmology. In this lecture I introduce what the TRGB is, how to use the TRGB for galaxy distance estimation, and their applications to cosmology. |
