Galaxy/Quasar-Dark-Matter-Halo Connection of DESI: A Generalized Subhalo Abundance Matching Approach for Multiple Tracers
LCDM is the standard model of modern cosmology with two dark components, dark matter and dark energy. The nature of dark energy and the dark matter structure growth rate can be probed via the large-scale structure (LSS). For this purpose, we observe millions of spectra of galaxies and quasars (QSOs) with spectroscopic galaxy surveys to explore the 3D map of the Universe. Meanwhile, high-resolut...

A multi-band, multi-resolution view of hot Jupiter atmospheres
With the rapidly increasing number of newly discovered exoplanets, the characterization of their atmospheres is becoming the new frontier, crucial for distinguishing between different planetary populations and bearing the imprints of planet formation and evolution. To this end, transit spectroscopy has been the most fruitful technique, revealing the atmospheric species for dozens of exoplanets,...

Identification of exotic binaries in globular clusters
I will present my work on identifying faint X-ray sources in multiple Galactic globular clusters (GCs). These X-ray sources could be close binaries hosting compact stellar remnants (white dwarfs, black holes, and neutron stars) and magnetically active binaries. For some GCs, we incorporate deep radio imaging data in our analyses to reveal potential candidates of millisecond pulsars and accretin...

Toward Accurate Metallicity Measurements in ISM and Distribution of HI in CGM from 3D Spectroscopy
Galaxies in the universe are intricately connected to the gas in and around galaxies. Accurately measuring the statistical properties of this gas is crucial for testing modern theories of galaxy formation and evolution. In this talk, I will present our recent efforts to characterize interstellar and circumgalactic media using integral field spectroscopy with high sensitivity in two aspects. 1) ...
