Missing Baryons Found in Far-Out Reaches of Galactic Halos

Photo - A new study has found that a share of particles that has gone missing is most likely located at the distant bounds of galaxy haloes. The study found some of these particles of baryonic matter located about 6 million light-years from their galactic centers. This color-rendered image shows the halo of the Andromeda galaxy, which is the Milky Way’s largest galactic neighbor. (Credit: NASA)

Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle

Image - An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions.

New Technique Looks for Dark Matter Traces in Dark Places

Illustration - In this composite image, theorized particles of decaying dark matter should produce a spherical halo of X-ray emission – represented here as colorized matter concentrated around the center of the Milky Way (in black and white) – that could be detectable when looking in otherwise blank regions of the galaxy.

A New Filter to Better Map the Dark Universe

Photo illustration - Just as the wine glass distorts an image of the cosmic microwave background in this photo illustration, large objects like galaxy clusters and galaxies can similar distort this light to produce lensing effects. (Credit: Emmanuel Schaan and Simone Ferraro/Berkeley Lab)
