Research Contents

As an astrophysics researcher, my work is focusing on galaxy formation, super (intermediate) massive black holes, chemical enrichment, and interstellar dynamics. We have provided evidence of metal pollution driven by stellar feedback, offering insights into stellar processes' impact on the interstellar medium. We also explored how mergers trigger starbursts in dwarf galaxies despite metal-deficient environments, shedding light on their evolutionary pathways.

Furthermore, I've investigated the dynamics of ionized and molecular gases in galactic nuclei, revealing insights into phenomena like star formation and AGN feedback. My researches also delved into the mass-metallicity relation, uncovering complex relationships between galactic properties and chemical makeup. Through meticulous analysis, we shed light on how gas-phase metallicity, stellar mass density, and star formation rates intertwine to shape galaxy evolution.

Moving forward, I will try to pushing the boundaries of our understanding of the universe, driven by curiosity and a dedication to advancing astrophysics research.
