Task Description and Goals

Despite fruitful results collected over the years, what is dark energy, remains one of the most fundamental yet unresolved questions in astrophysics. Using galaxies detected in the visible light, many state-of-the-art astronomical experiments have been devised and designed to measure the effect of dark energy on the expansion of the universe. However, due to the fact that most galaxies becoming dimmer in optical in further distance, these experiments are highly incomplete in the early times. Fortunately, a population of dark galaxies - dark in visible light but bright in submillimeter - have recently been found to exist predominantly at high redshifts, making them a potentially alternative probe to the dark energy in the early universe. During the summer program, the student will use cosmological simulations with considerations of the properties of dark galaxies and calculate the constraining power of these galaxies on key cosmological parameters. The forecasts based on this work will be invaluable to informing the design of future submillimeter large-scale surveys.

Required Background

Basic knowledge of physics and mathematics.
