Observing population III stars in the pristine region
Sung Kei Li, Jose M. Diego, Jose M. Palencia
The detection of the long-sought Population III (Pop III) stars is, perhaps, one of the most intriguing missing links in modern astronomy. Caustic crossing events (CCE) -- extreme…
Model independent lensing sub-structure detection with multiply-imaged star clusters constellations
Leo W. H. Fung, Tom Broadhurst, Sung Kei Li +3
A broad class of dark matter (DM) models predicts the existence of sub-structures residing in DM haloes on sub-resolvable angular scales. Techniques to extract such a generic featu…
Extragalactic microlensing through Ultra Diffuse Galaxies
Sung Kei Li, Thomas Broadhurst, Jose M. Diego +4
Stellar microlensing is a powerful method to constrain compact dark matter models, uncover binary stars, and exoplanets during caustic crossing events. At cosmological distances, {…
Massive stars as gravitationally lensed transients -- Insights on the high-mass initial mass function
Sung Kei Li
A robust stellar initial mass function (IMF) is crucial in any studies related to star formation. However, the direct measurement of the stellar IMF is confined to the local univer…
