Directly imaging the cooling flow in the Phoenix cluster - NatureThe cooling flow problem in galaxy clusters is linked to black hole jets maintaining hot gas temperatures.Recent observations indicate a rapid cooling event in the Phoenix cluster's intracluster medium.
This weird JWST trick lets us "see" dark matterDark matter's gravitational effects underpin multiple cosmic phenomena, and new techniques enable rigorous mapping of its distribution through faint light emissions in galaxy clusters.
Epic Gravity Lens Lines Up Seven-Galaxy ViewGravitational lensing enables deeper observations of the universe, providing multiple views of distant galaxies and valuable information about dark matter and dark energy.
