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…

A GMRT 610 MHz radio survey of the North Ecliptic Pole (NEP, ADF-N) / Euclid Deep Field North

Glenn J. White, L. Barrufet, S. Serjeant +17

This paper presents a 610 MHz radio survey covering 1.94 square degrees around the North Ecliptic Pole (NEP), which includes parts of the AKARI (ADF-N) and Euclid, Deep Fields Nort…

A luminous and young galaxy at z=12.33 revealed by a JWST/MIRI detection of Hα and [OIII]

Jorge A. Zavala, Marco Castellano, Hollis B. Akins +37

The James Webb Space Telescope (JWST) has discovered a surprising population of bright galaxies in the very early universe (<500 Myrs after the Big Bang) that is hard to explain wi…
