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.
Whipping up a cluster ft. Radio-loud AGN
Read on to learn how radio observations are uncovering hidden AGNs and what this means for our understanding of protocluster evolution.
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.
