Ultra High-Redshift or Closer-by, Dust-Obscured Galaxies? Deciphering the Nature of Faint, Previously Missed F200W-Dropouts in CEERS
G. Gandolfi, G. Rodighiero, L. Bisigello +42
The James Webb Space Telescope (JWST) is revolutionizing our understanding of the Universe by unveiling faint, near-infrared dropouts previously beyond our reach, ranging from exce…
Serendipitous Discovery of an Optically-Dark Ultra-Luminous Infrared Galaxy at = 3.4
N. H. Hayatsu, Zhi-Yu Zhang, R. J. Ivison +10
Dusty, submillimeter-selected galaxies without optical counterparts contribute a non-negligible fraction of the star formation in the early universe. However, such a population is…
Machine learning based Photometric Redshifts for Galaxies in the North Ecliptic Pole Wide field: catalogs of spectroscopic and photometric redshifts
Taewan Kim, Jubee Sohn, Ho Seong Hwang +13
We perform an MMT/Hectospec redshift survey of the North Ecliptic Pole Wide (NEPW) field covering 5.4 square degrees, and use it to estimate the photometric redshifts for the sourc…
The ALPINE-ALMA [CII] Survey: Unveiling the baryon evolution in the ISM of star-forming galaxies
P. Sawant, A. Nanni, M. Romano +28
Recent observations reveal a rapid dust build-up in high-redshift galaxies (z > 4), challenging current models of galaxy formation. While our understanding of dust production and d…
