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, {…
Delayed Feedback in High- Starbursts Revealed by Lyman- Profiles and Metal Line Diagnostics
James Nianias, Jeremy Lim, Yik Lok Wong +1
Lyman- emission, which couples strongly to gas kinematics, is a key observable for probing outflows from star-forming galaxies in the early universe. Inferences of outflow prop…
Transient star B/R ratio and star formation in lensed galaxies
Sung Kei Li, Jose M. Palencia, Jose M. Diego +8
The extreme magnification from galaxy clusters and microlenses therein allows the detection of individual, luminous stars in lensed galaxies as transient events, and hence provides…
Constraining the z 1 Initial Mass Function with {\it HST} and {\it JWST} Lensed Stars in MACS J0416.1-2403
Sung Kei Li, Jose M. Diego, Ashish K. Meena +19
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date, the IMF is constrained only to local galaxies. Indiv…
Tracing Outflows from Stellar Feedback in the Early Universe with Lyman-
James Nianias, Jeremy Lim, Yik Lok Wong +3
Blind spectroscopy of massive lensing galaxy clusters with MUSE has revealed large numbers of gravitationally-lensed Lyman- emitters exhibiting asymmetric profiles at $ 2.9 \le…
On the Evidence for Molecular Outflows in High-redshift Dusty Star-forming Galaxies
James Nianias, Jeremy Lim, Michael Yeung
Galactic-scale outflows of molecular gas from star-forming galaxies constitute the most direct evidence for regulation of star formation. In the early universe (), such ou…
A Lens Finder Map to check claimed High-z Galaxies behind SMACS J0723.3-7327
Alex Chow, Sung Kei Li, Tom Broadhurst +5
The first science image released by the JWST reveals numerous galaxies in the distant background of the galaxy cluster SMACS J0723.3-7327. Some have claimed redshifts of up to $z \…
