Non-thermal pressure in galaxy clusters: methods, models, constraints
I will discuss the role of non-thermal pressure support as a major source of the difference between the hydrostatic and the total ``true'' halo mass in galaxy clusters. I will present new models and methods to constrain the non-thermal pressure, highlighting the role of the next generation of X-ray observatories, like XRISM and NewAthena, in constructing a consistent picture of the formation an...

New Insights into Exoplanets: Connecting Theory with Measurements from Space and Lab
The discovery of thousands of exoplanets in our galaxy has unveiled an extraordinary diversity in planetary compositions and properties, challenging conventional theories of planet formation and evolution. These observations have spurred the development of new theoretical models that incorporate additional physical processes to bridge the gap between theory and data. Informed by recent high-pre...

Metallicity Correlations in Galaxies
Integrated field unit (IFU) spectroscopy provides a unique window to explore gas-phase oxygen abundances in the interstellar medium (ISM) of galaxies in the local Universe. Two-point correlations are one of the next-generation methodologies proposed to extract new information on ISM diffusion from metal fields inside galaxies. I will present two-point correlation analyses using CALIFA and MUSE ...

eROSITA Survey of the Hot Gaseous Halo of the Member Galaxies in Virgo
The X-ray-emitting hot gas is one of the primary components of the X-ray emission in normal galaxies and is crucial for understanding the evolution of the galactic ecosystem. The Virgo Cluster is the nearest and a rich galaxy cluster at its early evolutionary stage, which offers a great opportunity to study the hot gas content of its member galaxies and the cluster environmental effects. In thi...

Active galactic nuclei and mergers in IR-bright galaxies
The interaction of galaxies is known to regulate the star-formation activities in the merging systems, or galaxy pairs, however, whether and how such interactions affect the central supermassive black hole, often manifested as active galactic nuclei---AGNs, is still under debate. Controversies exist as to whether AGN activities are enhanced or suppressed during the different merging phases. The...
