Data obtained by the new James Webb Space Telescope was used by a recent study that has produced the most complete analysis to date of the intracluster light, the diffuse and faint light emitted by stars in galaxy clusters that are not gravitationally bound to any galaxy. The research gives new clue

Infrared wavelengths allow us to explore clusters of galaxies in a different way than with visible light. Thanks to its efficiency at infrared wavelengths and the sharpness of the images of the Webb, IAC researchers Mireia Montes and Ignacio Trujillo have been able to explore the intracluster light from SMACS-J0723.3-7327 with an unprecedented level of detail.
In order to analyze this extremely faint “ghostly” light, as well as needing the observational capability of the new space telescope, the researchers have developed new analysis techniques, which improve on existing methods. “In this work, we needed to do some extra processing to the Webb images to be able to study the intracluster light, as it is a faint and extended structure. That was key to avoid biases in our measurements“ says Mireia.
