Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Physical conditions in H II galaxies
The Astrophysical Journal, 1988 The temperature of the ionizing radiation T(ion) and the mean nebular ionization parameters U-bar were measured for a sample of 45 H II galaxies with estimated oxygen abundances in the range log O/H = -4.9 to -3.6. A simple, Stromgren sphere model is shown to fit very well all but three of the objects. The sensitivity of emission-line strength to T(ion)

Automation and Augmentation in Theological Perspective
Modern Theology, EarlyView.Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

The Astrophysical JournalThe nascent methodology of applying the principles of causal discovery to astrophysical data has produced affirming results about deeply held theories concerning the causal nature behind the observed coevolution of supermassive black holes (SMBHs) with ...

Simulations All the Way Up! An Atheist's Response to the Fine‐Tuning Argument
Analytic Philosophy, EarlyView.ABSTRACT So the Fine‐tuning Argument goes, because it is so unlikely for the physical constants of the laws of nature to have taken the values that they in fact take, we should significantly raise our credence that God exists. Simulation Arguments argue that our world might be (or, in stronger versions, that it probably is) a mere computer simulation ...

The Impact of Void-finding Algorithms on Galaxy Classification
The Astrophysical JournalWe explore how the definition of a void influences the conclusions drawn about the impact of the void environment on galactic properties using two void-finding algorithms in the Void Analysis Software Toolkit: Voronoi Voids ( V ^2 ), a Python ...

Where giants dwell: Probing the environments of early massive quiescent galaxies
Astronomy & AstrophysicsWe investigated the environments of massive quiescent galaxies at 3 ≲ z ≲ 5 using the GAlaxy Evolution and Assembly (GAEA) theoretical model. We selected galaxies with stellar mass above 1010.8 M⊙ and specific star formation rates below 0.3 × t−1 ...

Philosophy and Phenomenological Research, EarlyView.ABSTRACT Bayesian epistemology faces serious challenges when dealing with self‐locating evidence. This paper argues that, given two modest assumptions about how confirmation should work (Patterning and Live Centers), Bayesianism faces an unavoidable dilemma.

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

The Astrophysical JournalWe examined the double red clump (RC) observed in the Galactic bulge, interpreted as a difference in distance (“X-shaped bulge scenario”) or in chemical composition (“multiple population scenario”).
