Dusty starbursts masquerading as ultra-high redshift galaxy in JWST CEERS observations

Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-frame UV photons, these sources are expected to drop out in the bluer filters while being well-detected in redder filters. However, here we show that... Show more
