The Astrophysical JournalWe present a new self-consistent semianalytic model of the first stars and galaxies to explore the high-redshift ( z ≥ 15) Population III (PopIII) and metal-enriched star formation histories.

Astronomy & AstrophysicsPopulation III stars supplied the first light and metals in the Universe, setting the pace of re-ionisation and early chemical enrichment. In dense halos, their evolution can be strongly influenced by the energy released when weakly interacting massive ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background This study investigated how neighborhood‐level social determinants of health (SDOH), including redlining and neurological risk, interact to influence cognitive outcomes in children treated for brain tumors (CTBT). Methods A retrospective chart review of 161 CTBT aged 5–17 was conducted.

Zero Metallicity with Zero CPU Hours: Masses of the First Stars on the Laptop
The Astrophysical JournalWe develop an analytic model for the mass of the first stars forming in the centers of primordial gas clouds as a function of host halo mass, redshift, and degree of rotation.

Protostellar Feedback Processes and the Mass of the First Stars
, 2010 We review theoretical models of Population III.1 star formation, focusing on the protostellar feedback processes that are expected to terminate accretion and thus set the mass of these stars.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Objective To compare the efficacy and safety of roxarestat versus recombinant human erythropoietin (rhEPO) in the management of renal anemia in patients undergoing maintenance hemodialysis. Methods This was a prospective, open‐label, randomized controlled trial.

Recovery from population III supernova explosions and the onset of second generation star formation
, 2014 We use cosmological simulations to assess how the explosion of the first stars in supernovae (SNe) influences early cosmic history. Specifically, we investigate the impact by SNe on the host systems for Population~III (Pop~III) star formation and explore

Cosmological consequences of Population III stars
The Astrophysical Journal, 1984 We examine the possible cosmological consequences of Population III stars. Their dark remnants could provide the ''missing mass.'' Their light could have produced either the entire 3 K background or observable distortions in its spectrum. Their heat or explosions could have reionized the universe and perhaps produced galaxies.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Discovery of an [Fe/H] ∼ −4.8 Star in Gaia XP Spectra
The Astrophysical Journal LettersWe report on the discovery of GDR3_526285 (Gaia DR3 Source ID 5262850721755411072), a star with [Fe/H] = −4.82 ± 0.25 and one of the lowest metal (atomic number > 2) mass fractions ever found ( Z _GDR3 _ _526585 ≲ 1.0 × 10 ^−6 ).
