The components of the extragalactic γ-ray background (EGB) have been a puzzle since its discovery four decades ago 10. Recently, the Large Area Telescope (LAT) on Fermi provided a fifty-month ...

OBSERVATIONS of the diffuse X-ray background above approximately 20 keV, made from balloon platforms1–3, indicate a spectral index for the photon flux of at least 2 magnitudes. Recent rocket ...

Analysis of this data, which resolves about 60% of the 5-10 keV X-ray background, tends to indicate that many of these sources are probably obscured Seyfert galaxies and quasars.

Using the AstroSat spacecraft, Indian astronomers have observed a soft X-ray transient known as MAXI J0637−430. Results of the study, published February 18 on the arXiv pre-print repository ...

According to study co-author Daniel Gruen, this correlation suggests that dark matter may be largely responsible for the universe's faint gamma-ray background.
