Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
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…
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…
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…
