My name is Man Yin Leo Lee, but please call me Leo. I earned my Bachelor's degree in Physics from the University of Hong Kong (HKU) in 2021 and my Master of Philosophy in Physics from the Chinese University of Hong Kong (CUHK) in 2024. I am currently studying for my doctoral degree at the University of California, San Diego (UCSD).
I focus on spectroscopic analysis of the interstellar medium and astronomical instrumentation. Previously, I used stacked spectra of MaNGA galaxies to measure the temperature of the ISM within red, quiescent galaxies. I was also involved in developing an upcoming spectrograph called AMASE.
Ionization source(s) of LINERs
In old non-starforming galaxies, regions with emission line dominated by low ionization species are classified as Low-Ionization Nuclear Emission Regions (LINERs). The ionization mechanism behind such regions remains a lasting mystery. The possible candidates need to be distinguished with in depth analysis. In this project we try to measure their temperature by analyzing the spectroscopic data from SDSS MaNGA.
The AMASE project
I have been actively involved in the development of AMASE, an integral field spectrograph specifically designed to study the ionized gas present in the Milky Way and nearby star-forming galaxies. Throughout the project, my main research focus has been on the multimode fibers used in the spectrograph, involving tests to examine their properties and development of various techniques for fiber alignment, polishing, and insertion.
