Abstract: Our understanding of the universe primarily comes from observing the electromagnetic waves emitted by celestial objects. 3-D spectra offer a spectrum for each pixel in 2-D spatial dimensions and have been frequently employed in optical and radio bands to explore the Universe. In this talk, I will present our works to illustrate how the 3-D spectra play key roles in understanding the nature of dark matter, searching for intermediate massive black holes, constraining the cosmic structure growth, and potentially helping address one of today’s most significant cosmological challenges — the Hubble tension.
Bio: Yong Shi experts in observational astronomy, focusing on galaxy evolution, active galactic nuclei and cosmologies. He received his bachelor’s degree from Peking University in 2003 and his Ph.D. in astronomy from the University of Arizona in 2008. He completed postdoctoral research at the University of Arizona and the California Institute of Technology from 2009 to 2012. Since 2013 he is a professor at School of Astronomy and Space Science in Nanjing University. He was awarded funding from the Young Thousand Talent Program in 2013, NSFC for Distinguished Young Scholars in 2018, and the Xplore Prize in 2019.
