Witnessing the Birth of Planets: The Structure and Chemistry of Planet-Forming Disks
To date, there are more than 5000 exoplanets discovered in our neighborhood, showcasing a remarkable diversity in planetary system architectures. Unraveling the planet formation process, as well as the origin of this diversity, requires a comprehensive understanding of their birth sites - the dusty and gas-rich disks orbiting around young stars. ALMA’s unprecedented spatial resolution and sens...

Deciphering Galaxy Quenching: Insights from the Multiphase Circumgalactic Medium
In the galactic ecosystem, the circumgalactic medium (CGM) is a massive baryon reservoir orchestrating baryonic inflows and outflows, shaping galaxy formation and evolution. Of profound significance is the quenching of cosmic star formation since cosmic noon, pivotal in unraveling present-day galaxy characteristics, yet its driving force remains uncertain. Characterizing and modeling the CGM em...

The lively radio transient sky
Making use of exponential increases in computing power, radio astronomers have been able to search larger areas of the sky at high time and frequency resolution. These surveys facilitate the studies of radio transients, particularly contributing to the thriving investigation of fast radio bursts (FRBs), enigmatic radio bursts observable at cosmological distances. I will provide an overview of t...

Probing Planet Formation with the Most Extreme Cases
Thousands of exoplanets have been discovered in the past ~30 years. However, there are still major gaps of knowledge in our understanding of planet formation. The most extreme exoplanets are often ideal for identifying, isolating, and investigating critical aspects of plant formation. In this talk, I will highlight three extremes of planet formation: 1) the ultra-short-period planets (

Studying Particle Transport in the Magnetic Turbulence with Pulsar Wind Nebulae/Pulsar Halos with Multiwavelength Observations
Pulsar wind nebulae and pulsar halos are extended sources of nonthermal radiation powered by pulsars. Morphologies of these sources reflect the spatial distribution of electrons/positrons therein, which is related to the particle transport mechanism and the turbulent nature of the background medium. Therefore, multiwavelength observations of pulsar wind nebula and pulsar halos provide a good op...
