Results 61 to 70 of about 103,015 (280)
The Astrophysical Journal Letters, 2023 We present the results of 0.″6-resolution observations of CO J = 3 − 2 line emission in 10 massive star-forming galaxies at z ∼ 2.2–2.5 with the Atacama Large Millimeter/submillimeter Array (ALMA).

High-redshift Galaxies and Black Holes Detectable with the JWST: A Population Synthesis Model from Infrared to X-Rays [PDF]
, 2017 The first billion years of the Universe has been a pivotal time: stars, black holes (BHs), and galaxies formed and assembled, sowing the seeds of galaxies as we know them today.

The problematic growth of dust in high-redshift galaxies [PDF]
, 2016 Dust growth via accretion of gas species has been proposed as the dominant process to increase the amount of dust in galaxies. We show here that this hypothesis encounters severe difficulties that make it unfit to explain the observed UV and IR ...

CEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3–9 with JWST
The Astrophysical Journal Letters, 2023 We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3–9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z

Extended Lyman α haloes around individual high-redshift galaxies revealed by MUSE [PDF]
, 2015 We report the detection of extended Ly alpha emission around individual star-forming galaxies at redshifts z = 3-6 in an ultradeep exposure of the Hubble Deep Field South obtained with MUSE on the ESO-VLT.

Reionisation and High-Redshift Galaxies: The View from Quasar Absorption Lines [PDF]
Publications Astronomical Society of Australia, 2015 Determining when and how the first galaxies reionised the intergalactic medium promises to shed light on both the nature of the first objects and the cosmic history of baryons.

The distribution of neutral hydrogen around high-redshift galaxies and quasars in the EAGLE simulation [PDF]
, 2015 The observed high covering fractions of neutral hydrogen (HIHI) with column densities above ∼1017 cm−2 around Lyman-Break Galaxies (LBGs) and bright quasars at redshifts z ∼ 2–3 has been identified as a challenge for simulations of galaxy formation.

ChemPhysChem, Volume 26, Issue 18, September 19, 2025.In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.
