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…
The PAU Survey: The -band galaxy luminosity function from the present-day to
S. Koonkor, C. M. Baugh, G. Manzoni +13
We present a measurement of the -band galaxy luminosity function from the present-day to , using over 1.1 million galaxies from the Physics of the Accelerating Universe S…
The PAU Survey: Uncovering the connection between intrinsic and observed galaxy properties using symbolic regression
Adarsh Kumar, Carlton M. Baugh, Suttikoon Koonkor +12
Estimating stellar masses for billions of galaxies in upcoming surveys requires methods that are both accurate and computationally efficient. We present a new approach using symbol…
Magnification bias reveals severe contamination in Hubble Frontier Field photo-z catalogs
Jiashuo Zhang, Jeremy Lim, Tom Broadhurst +4
Gravitational lensing by massive galaxy clusters enables faint distant galaxies to be more abundantly detected than in blank fields, thereby allowing one to construct galaxy lumino…
Survival of the Fittest: Testing Superradiance Termination with Simulated Binary Black Hole Statistics
Hui-Yu Zhu, Xi Tong, Giorgio Manzoni +1
The superradiance instability of rotating black holes leads to the formation of an ultralight boson cloud with distinctive observational signatures, making black holes an effective…
Explaining JWST counts with galaxy formation models
Giorgio Manzoni, Tom Broadhurst, Jeremy Lim +18
A distinct power-law break is apparent m_AB approximately 21 in the deep Near-Infrared PEARLS-JWST galaxy counts. The break becomes more pronounced at longer wavelengths, with the…
