Rotation curve of the typical spiral galaxy M 33 (yellow and blue points with error bars) and the predicted one from the distribution of the visible matter (white line). The discrepancy between the two curves is accounted for by adding a dark matter halo surrounding the galaxy.

FASER, Neutrinos, and Dark Matter…
Topics: CERN, Dark Matter, High Energy Physics, Neutrinos, Particle Physics Neutrinos are ubiquitous and notorious. Billions are passing through you at this moment. Occasionally described as a “ghost of a particle,” neutrinos are nearly massless, thereby making them extremely difficult to detect experimentally (“Neutrino,” meaning “little neutral one” in Italian, was first used by Enrico FermiContinue reading “FASER, Neutrinos, and Dark Matter…”
Clocking Dark Matter…
Topics: Dark Matter, Modern Physics, Quantum Mechanics An optical clock has been used to set new constraints on a proposed theory of dark matter. Researchers including Jun Ye at JILA at the University of Colorado, Boulder, and Andrei Derevianko at the University of Nevada, Reno, explored how the coupling between regular matter and “ultralight” dark matter particles could beContinue reading “Clocking Dark Matter…”
