It is filtered to emphasize point sources. f090 is the band that's most sensitive to active galactic nuclei, our most common type of point source. Galaxy clusters are also visible through the tSZ effect, showing up as small dark spots. For a slightly deeper map, we combine the DR4 based on Atacama Cosmology Telescope (ACT) data from 2013-2016 and the ACT DR6, based on data collected with the AdvancedACT camera over the period 2017-2022.https://alasky.cds.unistra.fr/ACT/DR4DR6/f090SurveyResearchIsDerivedFromSigurd Kirkevold Naess (Institute for theoretical astrophysics, University of Oslo)This HiPS is distributed under ODbL license by Unistra/CNRShttps://alasky.cds.unistra.fr/ACT/DR4DR6/f090https://alaskybis.cds.unistra.fr/ACT/DR4DR6/f09057878 597626.294766642499055e-23 6.294766642499055e-23https://alasky.cds.unistra.fr/ACT/DR4DR6/f090/Moc.fitsRadio
