The infrared glow of the first stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2006 Abstract Kashlinsky et al. find a significant cosmic infrared background fluctuation excess on angular scales ≳50 arcsec that cannot be explained by instrumental noise or local foregrounds. The excess has been tentatively attributed to emission from primordial, very massive (Population III, hereafter PopIII) stars formed ≤ 200 Myr after ...SALVATERRA, R, MAGLIOCCHETTI, M, FERRARA, ANDREA, SCHNEIDER, R. +3 moreopenaire +4 more sourcesBreaking through the cosmic fog: JWST/NIRSpec constraints on ionizing photon escape in reionization-era galaxies
Astronomy & AstrophysicsAims. The escape fraction of Lyman continuum photons (fesc(LyC)) is the last key unknown in our understanding of cosmic reionization. Directly estimating the escape fraction (fesc) of ionizing photons in the epoch of reionization (EoR) is impossible, due Giovinazzo Emma, Oesch Pascal A., Weibel Andrea, Meyer Romain A., Witten Callum, Bhagwat Aniket, Brammer Gabriel, Chisholm John, de Graaff Anna, Gottumukkala Rashmi, Jecmen Michelle, Katz Harley, Leja Joel, Marques-Chaves Rui, Maseda Michael, Shivaei Irene, Trebitsch Maxime, Verhamme Anne +17 moredoaj +1 more sourceEuclid: Discovery of 31 new quasars at 6.6 < z < 7.8★

, 2006 We use high-resolution simulations to show that the current standard paradigm for the growth of structure in the Universe predicts the formation of a galaxy like our own to differ substantially from the classic ELS and Searle/Zinn pictures. On scales larger than the Local Group, the earliest star formation was extremely inhomogeneous, suggesting that ...White, Simon D.

Astronomy & Astrophysics, 2015 We propose and apply a new classification for the CEMP-no stars, which are "carbon-enhanced metal-poor" stars with no overabundance of s-elements and with [Fe/H] generally inferior or equal to -2.5. This classification is based on the changes in abundances for the elements and isotopes involved in the CNO, Ne-Na, and Mg-Al nuclear cycles.{Maeder} A., {Meynet} G.openaire +2 more sourcesGLIMPSE-D: Metallicity decline in faint galaxies: Implications for [O III]+Hβ luminosity function and re-ionisation budget

Monthly Notices of the Royal Astronomical Society, 1983 Primordial clouds are likely to be remarkably uniform over stellar mass-scales in the absence of a pre-existing generation of stars. Thermal instability is found to occur during the collapse of a primordial cloud when the H2 abundance is rising and the H2 optical depth is of order unity.openaire +1 more source
