Dark Matter Gets a Weight Check: The Strongest Lower Bound Yet
Today’s paper has come up with the an model independent way to put a lower limit on dark matter particles!
Less than meets the eye: measuring the bias in galaxy cluster observations
Today’s authors come up with a new way to account for foreground and background galaxies in galaxy cluster measurements.
Hidden Objects in our backyard? The First -ray emission measurement around several TeV by LHAASO
This study by the LHAASO Collaboration presents the first measurement of diffuse gamma-ray emissions in the 1–25 TeV range, revealing excess flux beyond theoretical predictions. The findings suggest hidden gamma-ray sources, such as pulsar wind nebulae or massive star clusters, and indicate spectral variations across the Galactic plane. These results challenge existing cosmic-ray transport models and highlight the need for further observations and refined theoretical frameworks.
Do Galaxy Halos Convert Light Into Dark Matter?
Today’s paper explores the search for axion-photon oscillations in the CMB.
Is Dark Matter lurking in the infrared Background?
In today’s bite, we look at a novel way of searching for dark matter using the background of images of galaxies in infrared wavelengths.
So the Darkness Shall be Light: Roman’s View of Primordial Black Holes
There are numerous candidates for dark matter, including primordial black holes. Today’s paper addresses whether an upcoming NASA space telescope could detect these exotic black holes from the early universe.
