Mark Vogelsberger: Simulating galaxy formation for clues to the universe
“In astrophysics, we have only this one universe which we can observe,” the physics professor says. “With a computer, we can create different universes, which we can check.”
Six from MIT named American Physical Society Fellows for 2021
APS names Bourouiba, Grego, Liu, Peacock, Winslow, and Yildiz as MIT’s newest fellows for their contributions to physics.
New clues to why there’s so little antimatter in the universe
Radioactive molecules are sensitive to subtle nuclear phenomena and might help physicists probe the violation of the most fundamental symmetries of nature.
Fast-spinning black holes narrow the search for dark matter particles
Certain ultralight bosons would be expected to put the brakes on black holes, but new results show no such slowdown.
Astronomers image magnetic fields at the edge of M87’s black hole
New image of M87 reveals how it looks in polarized light.
Measuring the invisible
Particle physicist Lindley Winslow seeks the universe’s smallest particles for answers to its biggest questions.
Astronomers detect extended dark matter halo around ancient dwarf galaxy
Findings suggest the first galaxies in the universe were more massive than previously thought.
Search for axions from nearby star Betelgeuse comes up empty
Results significantly narrow the range of possible places to find the hypothetical dark matter particles.
Mark Vogelsberger wins 2020 Buchalter Cosmology Prize for simulating a “fuzzy” universe
Associate professor of physics shares the honor with colleague Phillip Mocz for their novel dark matter research.
New type of atomic clock keeps time even more precisely
The design, which uses entangled atoms, could help scientists detect dark matter and study gravity’s effect on time.
Pulling the secrets of dark matter out of a hat
Grad student Chiara Salemi and Professor Lindley Winslow use the ABRACADABRA instrument to reveal insights into dark matter.
This is how a “fuzzy” universe may have looked
Scientists simulate early galaxy formation in a universe of dark matter that is ultralight, or “fuzzy,” rather than cold or warm.
Dark matter experiment finds no evidence of axions
In its first run, ABRACADABRA detects no signal of the hypothetical dark matter particle within a specific mass range.
Modeling the universe
MIT's Mark Vogelsberger and an international astrophysics team have created a new model pointing to black holes’ role in galaxy formation.
