“The Universe before our time” by Stefanie Reichert Nature
Florian Kühnel and Katherine Freese studied the impact of quantum fluctuations of the scalar field driving inflation on primordial black hole formation. They calculated the power and mass spectra for a field with inflection points, and found that primordial black hole formation is significantly enhanced. Hence, the effects of quantum fluctuations need to be taken […]
“Testing DAMA” by Jim Daley Symmetry Magazine
A confirmation that DAMA is indeed seeing dark matter would open another gold mine of sorts. Katherine Freese, a theoretical astrophysicist at the University of Texas, first proposed the technique of searching for an annual modulation of the dark matter signal in the galactic halo in 1986. Freese says that if the DAMA signal is […]
“Dark matter particles won’t kill you. If they could, they would have already” by Lisa Grossman ScienceNews
“As wacky as this might sound, physicist Katherine Freese thought these calculations were worth doing. “This study is fun,” says Freese of the University of Michigan in Ann Arbor. “Looking for macros in already existing detectors, such as the human body, is a good idea.” Though she wasn’t involved in the macro research, she and […]
“Dark Stars: Could be the Seed of Supermassive Black Holes” by Simone Caporali Everyeye.it
Le stelle oscure sono oggetti che potrebbero essere esistiti nell’universo primordiale, della cui esistenza non siamo totalmente certi, che se potrebbero rappresentare una possibile risposta all’esistenza dei buchi neri supermassicci. Non vi basta? Potrebbero essere alimentate e potenziate dalla materia oscura.
“If this type of dark matter existed, people would be dying of unexplained ‘gunshot’ wounds” by Juanita Bawagan Science
The Case Western team is not the only group of researchers trying to harness new ways to detect dark matter. Freese has developed paleo-detector experiments that would be sensitive enough to detect the traces of WIMPs in ancient minerals. However, rocks could also show signals of heavier dark matter—in more obvious ways. If macros collide […]
“Dark stars: The seeds of supermassive black holes?” by Jake Parks Astronomy
The early universe was a very different place than it is now. But it may have been the perfect environment for a strange class of giant, puffy stars that used dark matter as fuel.
“Interview with Million STEM”
Million STEM “Many women in STEM think they are not good enough. They think they have been awarded a position not because they are qualified but because they are lucky. This is never true.”
“Physicists Propose Hunting for Signs of Dark Matter in Ancient Minerals” by Ryan F. Mandelbaum
Gizmodo “Now, scientists are preparing to hunt for signatures of dark matter particles in the Earth itself. It might sound a little farfetched—but this strategy has some advantages over some current dark matter searches, which rely on massive, expensive, custom-built facilities. ‘We’re not going to build anything,” study author Katherine Freese, theoretical astrophysicist and professor […]
