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…
False Alarm Rate based Statistical Detection Limit for Astronomical Photon Detectors
Albert Wai Kit Lau, Leo W. H. Fung, George F. Smoot
In ultra-fast astronomical observations featuring fast transients on sub-s time scales, the conventional Signal-to-Noise Ratio (SNR) threshold, often fixed at , becomes inad…
Diverse dark matter haloes in Two-field Fuzzy Dark Matter
Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger +8
Fuzzy dark matter (FDM) is a compelling candidate for dark matter, offering a natural explanation for the structure of diffuse low-mass haloes. However, the canonical FDM model wit…
A smooth filament origin for distant prolate galaxies seen by JWST and HST
Alvaro Pozo, Tom Broadhurst, Razieh Emami +7
The initial gravitational collapse of Dark Matter and gas forms a universal filamentary network where the first galaxies form, with shapes and sizes that depend on the choice of Da…
Exploring the discrepancy between Planck PR3 and ACT DR4
Dhiraj Kumar Hazra, Benjamin Beringue, Josquin Errard +2
We explore the scales and the extent of disagreement between PR3 and Atacama Cosmology Telescope (ACT) DR4 data. and ACT data have substantial overlap in the temp…
Dark Matter distinguished by skewed microlensing in the "Dragon Arc"
Tom Broadhurst, Sung Kei Li, Amruth Alfred +18
Microlensed stars recently discovered by JWST & HST follow closely the winding critical curve of A370 along all sections of the ``Dragon Arc" traversed by the critical curve. These…
