| Galaxy-Halo Connection for Next Generation Galaxy Surveys |
| Seminar Title | Galaxy-Halo Connection for Next Generation Galaxy Surveys
| | | | | Speaker: | Dr. ZUYin | | | | | Affiliation: | (SJTU) | | | | | When | Thursday afternoon, Jan. 10, 15:00 p.m. | | | | | Where: | Room 212, Astronomy Building | | | Welcome to Attend | | | | | ( PMO Academic Committee & Academic Circulating committee) | | | Abstract： We will be inundated with precise measurements of tens of millions of galaxy spectra, half million HI emission detections, and billions of galaxy images from future surveys like DESI, FAST, and LSST, respectively.Combined with high-resolution cosmological simulations, the tremendous statistics will enable robust inference of the probabilistic connection between galaxies and their underlying dark matter halos. I will briefly review the recent development in the studies of galaxy-halo connection, and introduce a novel probabilistic framework for maximizing the scientific return from survey data. I will further argue that this framework provides an exciting avenue for understanding the physics behind the fueling and quenching of star-formation activities in galaxies, independent of and orthogonal to the conventional semi-analytic models or hydro-dynamic simulations. Looking to the future, I will discuss the prospect of revealing the co-evolution of blackholes, stars, gas, and dark matter halos from the combination of DESI, LSST, and FAST. |
