Salak Lab
Machine-translated · View original
An astronomy lab that explores galaxy evolution with radio telescopes.
AboutAbout the lab
Exploring the birth and evolution of galaxies through radio observations
The Salak Lab studies how galaxies were born and have evolved, using observations from radio telescopes.
Its targets include galaxies in the early universe, dust-obscured galaxies and quasars, and active galactic nuclei and star formation in nearby galaxies.
For observations of molecular and atomic gas, the lab mainly uses radio telescopes such as the Atacama Large Millimeter/submillimeter Array (ALMA).
Key terms
- quasar
- An active galactic nucleus at the center of a galaxy that appears especially bright.
- active galactic nucleus
- A region at the center of a galaxy that can shine as intensely as the entire galaxy.
- molecular gas
- Cold gas in which hydrogen and other elements are in molecular form. It is the material from which stars are born.

This lab studies galaxy evolution through observations. Mainly using radio telescopes to observe molecular and atomic gas, it targets galaxies from many epochs, from the early universe to nearby galaxies.
*Illustrative imageBirth and Evolution of Galaxies in the Early Universe
The lab studies how galaxies formed and how they evolved early on during the first billion years or so of the universe, the epoch of reionization at redshift 6 and above.
*Illustrative imageDust-Obscured Galaxies and Quasars
The lab studies dust-enshrouded galaxies and quasars from the era known as cosmic noon (redshift 1–3).
*Illustrative imageCold Gas in Nearby Galaxies
In nearby galaxies, the lab studies cold gas related to active galactic nuclei, star formation, and secular evolution, the slow transformation of galaxies over time.
