Galaxy 3D structure formation and evolution across cosmic time

Speaker: Junkai Zhang (Tsinghua University)

Venue: Video Conference

Time: 12:30 PM, Monday, Apr. 8, 2024

Abstract: 

The evolutionary histories of galaxies leave an imprint on their structure. A complete understanding of the physical mechanisms behind galaxy evolution relies on observing galaxy structure back to earlier cosmic times. This talk will present my observation work on the 3D shapes of quiescent galaxies (QGs, part 1) and star-forming galaxies (SFGs, part 2) based on their projected shapes seen from random viewing angles, using a wedding cake of multi-wavelength photometric surveys (KiDS+VIKING, COSMOS2020) and high image quality surveys (HSC-SSP, 3D-DASH, CANDELS) complementary in area and depth, covering the redshift range 0<z<2.5.
