Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
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…
Infalling ultra-faint dwarfs as emissaries of the Axiverse
A. Pozo, T. Broadhurst, H. N. Luu +8
Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at kpc, considerably strengthens the case that UFDs constitute…
The Lifespan of our Universe
Hoang Nhan Luu, Yu-Cheng Qiu, S. -H. Henry Tye
The Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI) measurements claim that the dark energy equation of state . This observation can be expla…
Dynamical dark energy from an ultralight axion
Hoang Nhan Luu, Yu-Cheng Qiu, S. -H. Henry Tye
Recently the Dark Energy Survey (DES) Collaboration presented evidence that the equation of state of the dark energy is varying, or if it is constant. In eith…
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…
