Jan 19, 2021 by News Staff

First theorized in the 1970s, axions are hypothetical particles that were proposed to preserve a time-reversal symmetry of the nuclear force. These particles may make up dark matter and may be produced thermally inside the cores of neutron stars, escape the stars due to their feeble interactions with matter, and subsequently convert into X-rays in the magnetic fields surrounding the stars. In a paper in the journal Physical Review Letters, astrophysicists...

This Hubble image shows the barred spiral galaxy NGC 4535. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
