12 de ago. de 2022 · Zavala's team also followed up on two more galaxies with claimed high redshifts — Maisie's Galaxy at a redshift of 14.3 placing it 280 million years after the Big Bang, and a redshift 16.7 ...
23 de oct. de 2023 · Abstract: The 3D geometry of high-redshift galaxies remains poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently and robustly infer the 3D shapes of star-forming galaxies in JWST-CEERS observations with $\log M_*/M_ ...
4 de abr. de 2023 · Other high-redshift galaxy candidates selected from previous HST imaging were included in the masks, in addition to a broader selection of known and candidate galaxies at lower redshifts.
10 de ago. de 2014 · Dusty star-forming galaxies at high redshift. Far-infrared and submillimeter wavelength surveys have now established the important role of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of massive galaxies in the Universe. The brightest of these galaxies have infrared luminosities in excess of 10 13 L ⊙ ...
13 de abr. de 2023 · The theoretical expectation is that efficiencies do indeed increase at high redshift 28, although ϵ ≳ 0.57 is still highly extreme and probably implausibly high. If the explanation of the L23 galaxies is indeed a very high star formation efficiency, it implies that the star formation histories of such systems must rise steeply with time ...
16 de ago. de 2023 · Right-hand panel: eight z ≳ 12 JWST targets explored in this work with background illustrating the early stage of reionization (projected with a depth of 4 cMpc, a typical bubble radius for high-redshift bright galaxies) according to our fiducial model. References for these galaxy observations are listed in Table 1.Left-hand panel: the predicted mean neutral fraction (at later times ...
7 de dic. de 2021 · JWST will similarly provide a major technical improvement in our ability to observe high-redshift galaxies over current telescopes. However, JWST is a time-limited resource, with a nominal mission lifetime of 5 yr and a maximum telescope lifetime of ∼11 yr capped by consumables 4 and no servicing mission possible.
