Doomsday or Multiverse Bias

open access: yesPhilosophy 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.

Quantifying the Velocity Anisotropy Profile of Galaxy Clusters Using the Uchuu Cosmological Simulation

open access: yesThe Astrophysical Journal
Galaxy clusters are powerful laboratories for studying both cosmic structure formation and galaxy evolution. We present a comprehensive analysis of the velocity anisotropy profile, β ( r ), in galaxy clusters using the Uchuu-UniverseMachine mock galaxy ...

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental 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.

Distribution of Merging and Post-merger Galaxies in Nearby Galaxy Clusters

open access: yesThe Astrophysical Journal
We study the incidence and spatial distribution of galaxies that are currently undergoing gravitational merging (M) or that have signs of being post-merger (PM) in six galaxy clusters (A754, A2399, A2670, A3558, A3562, and A3716) within the redshift ...

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

The S-PLUS Fornax Project (S+FP): Mapping Globular Clusters Systems within 5 Virial Radii around NGC 1399

open access: yesThe Astronomical Journal
We present the largest sample (∼13,000 candidates, ∼3000 of which are bona fide candidates) of globular cluster (GCs) candidates reported in the Fornax cluster so far.

Simulating Galaxies and Galaxy Clusters

open access: yes, 2004
The X-ray luminosities of the hot halo gas around simulated, Milky Way like disk galaxies have been determined, as a function of redshift. The X-ray luminosity increases significantly with redshift, in some cases as much as a factor 30 going from z=0 to 2. Consequently, the optimal detection redshift can be >~0.5.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Emergence of the Galaxy Morphology–Star Formation Activity–Clustercentric Radius Relations in Galaxy Clusters

open access: yesThe Astrophysical Journal
We investigate when and how the relations of galaxy morphology and star-forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy clusters with total mass ${{M}}_{\mathrm{tot}}^{\mathrm{cl}}\gt 5\times {10}^{13}
