Welcome!
I am an astronomer at University of Massachusetts Amherst.
Here you can get a glimpse of my research activtities.
How galaxies get their gas and how much mass, energy, and metals
galaxies return to their surroundings are questions central to our
understanding of galaxies and the intergalactic medium. Only stars
synthesize metals. Yet only about half of the generated elements are
found in stars and the interstellar medium. Galaxies are also missing
their share of baryonic matter. Understanding the flows of the
matter/energy in and around galaxies, or their "ecosystem'', is the focus
of my research.
A key to the understanding of the matter and energy flows is the study
of various high-energy feedback processes in galaxies. I have
concentrated on four
closely-related aspects of this research topic:
- examining various high-energy sources of the
interstellar medium (e.g., supernova remnants, superbubbles, and
galactic nuclear regions);
- characterizing the global structure as well as the
physical and chemical states of hot gas in and around galaxies;
- investigating the interplay of the hot gas with other
galactic components;
- exploring the interaction of galaxies with their
environment, particularly the intragroup/cluster media.
I primarily uses infrared, ultraviolet, and X-ray
observations to conduct these studies. I also carry out theoretical and
computational studies with my students and collaborators.
