Evidence of First Stars-enriched Gas in High-redshift Absorbers
The Astrophysical Journal, 2023 The first stars were born from chemically pristine gas. They were likely massive, and thus they rapidly exploded as supernovae, enriching the surrounding gas with the first heavy elements.Andrea Saccardi, Stefania Salvadori, Valentina D’Odorico, Guido Cupani, Michele Fumagalli, Trystyn A.

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 sourceCentral Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background
Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.Samuel Sassine, Hallie Coltin, Sylvia Cheng, Lucie Lafay‐Cousin, Vanan Issai Magimairajan, Craig Erker, Stéphanie Vairy, Lynette Bowes, Adam Fleming, Donna Johnston, Sarah McKillop, Roona Sinha, Julie Bennett, Christina Coleman, Laura Wheaton, Shayna Zelcer, Samuele Renzi, Thai Hoa Tran +17 morewiley +1 more sourceNucleosynthetic signatures of the first stars [PDF]

Pediatric Blood &Cancer, EarlyView.ABSTRACT
High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...Krzysztof Wierbiłowicz, Se Whee Sammy Park, Aironas Los, Ernest Liu, Nona Struyf, Tom Erkers, Sören Lehmann, Jan J.

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
