“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 […]
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.
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 […]
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.
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.”
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 […]
Quanta Magazine “We’re always rooting around for alternative ways to do things,” said Katherine Freese, a theoretical physicist at the University of Michigan and architect of the ideas behind some of the existing detectors in operation. A subterranean paleo-detector would work in a manner similar to current direct-detection methods, according to Freese and her colleagues. […]
LSA Physics Dark stars may help solve a long-standing mystery concerning how supermassive black holes — like the one believed to reside at the center of the Milky Way, shown here — formed in the early universe.
ScienceNews “Performing an experiment made with the same material as DAMA is important, says Katherine Freese of the University of Michigan in Ann Arbor. ‘The fact that they’ve got a working sodium iodide detector is huge.” But, Freese says, what’s really needed to check DAMA’s claims is for COSINE to search for an annual change.”
