A Quick Sketch - Weichen Wang

I am currently a postdoc researcher at the University of Milano-Bicocca. My research is focused on (a) characterizing the formation of high-redshift galaxies in special cosmic environments and (b) detecting the diffuse cosmic gas called CGM/IGM in emission. Both efforts will provide us essential pieces to solve a critical puzzle of modern astronomy: what roles has the large-scale environment played in galaxy formation?

My research has been built upon observations with several major telescopes, including the JWST, VLT/MUSE and Keck/DEIMOS. The JWST programs I am heavily involved in can be found here and here. I work closely with Prof. Sebastiano Cantalupo and many other colleagues in the COSMIB group at Milan and around the world.

I defended my Ph.D. at the Johns Hopkins University in 2022. For my thesis, I studied the outflowing gas from galaxies (a.k.a. galactic winds) in the distant Universe. I worked with Dr. Susan Kassin and Prof. Tim Heckman. I also collaborated with Prof. Sandy Faber and Prof. David Koo at University of California, Santa Cruz. Before going to Baltimore, I spent my college life at Tsinghua University in Beijing, where I worked at Tsinghua Center for Astrophysics with Prof. Shude Mao on gravitational lensing (Find a roasted duck here).
