Feeding and feedback of the supermassive blackhole in brightest cluster galaxies
The intracluster medium (ICM) is the largest reservoir of the hot baryons. The centers of the ICM often feature a sharp X-ray surface brightness peak. AGN mechanical feedback from the brightest cluster galaxy is likely preventing the hot ICM from the catastrophic cooling, although the exact feedback process remains poorly understood. A growing number of kiloparsec-scale multiphase filaments hav...

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...
