Keep pulling the thread on Katherine Freese.
The James Webb Space Telescope has discovered galaxies in the early universe that are more developed than existing cosmological models predicted for that era.
The Dark Energy Spectroscopic Instrument (DESI) experiment has produced evidence suggesting that dark energy may be changing over time, causing the acceleration of the universe's expansion to slow down.
Physicist Katie Freese and collaborator Yun Wang re-analyzed data from the DESI experiment and found no strong evidence that dark energy is changing over time, contradicting the experiment's primary claim.
A theoretical object called a "dark star" is hypothesized to be one of the first stars, made of ordinary matter but powered by dark matter annihilation instead of nuclear fusion.
The James Webb Space Telescope has observed candidate objects that could be "dark stars," a theoretical type of star powered by dark matter.
Theoretical models predict that dark stars could grow to be a million times as massive as the sun and a billion times as bright.
The existence of dark stars could potentially explain the formation of supermassive black holes in the early universe and other unexplained objects observed by the James Webb Space Telescope.
The theoretical calculation of vacuum energy in physics produces a result that is larger than the observed value by a factor of 10 to the 120th power, one of the largest discrepancies in science.
The formation of galaxies and other large-scale structures in the universe required dark matter to first collapse into gravitational halos, which then attracted ordinary matter.
Scientists are actively searching for the existence of purely dark matter galaxies, which would be invisible but detectable through their gravitational lensing effects on background objects.
The Swedish government awarded physicist Katie Freese a $15 million grant over 10 years to study Cosmoparticle Theory at Stockholm University.
Most current dark matter detection experiments use large vats containing tons of liquid xenon to search for interactions with dark matter particles.
