The identification of the host systems of metal absorbers

Using the ALMA and JWST data, we construct the sample of early metals and their hosts (e.g., z>2) to study the correlation between metals and galactic properties and understand the baryonic cycle in the early universe.

Properties of dusty galaxies

In the JWST era, we are now able to observe the rest-frame optical emission from dust galaxies (submillimeter galaxies, SMGs). We dsicovered the most distant spiral galaxies ever found.

I enjoy recording sunsets and landscapes. Here are my favorite photos.
