Probing Spatial Variations in IGM Transmission: Higher Ly$α$ Visibility in an H$α$-Selected Galaxy Overdensity at $zsimeq6.2$

Posted by klaurent Peking, This Week: Astrophysics

Kavli Affiliate: Kohei Inayoshi | Summary:The visibility of Ly$α$ emission during the epoch of reionization depends on both galaxy properties and the transmission of Ly$α$ photons through the intergalactic medium (IGM). Using JWST/NIRCam F470N imaging, we identify a prominent projected overdensity of H$α$ emitters (HAEs) at $zsimeq6.2$ in CEERS field. We use Subaru/HSC NB872 imaging […]
