Hubble Tension and Observed Predictions of Universal Expansion
Advances in Astronomy, Volume 2026, Issue 1, 2026.The Hubble tension, a significant discrepancy between the Hubble constant values derived from cosmic microwave background measurements and local observations, challenges the standard model of cosmology. This report shows how the theory of universal expansion predicts the Hubble tension and many other observations.

Big Bang Nucleosynthesis, Population III, and Stellar Genetics in the Galactic Halo [PDF]
, 2002 The diverse isotopic and elemental signatures produced in different nucle- osynthetic sites are passed on to successive generations of stars. By tracing these chemical signatures back through the stellar populations of the Galaxy, it is pos- sible to ...

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain
Applied Research, Volume 4, Issue 6, December 2025.This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

Nucleosynthesis in Stellar Explosions [PDF]
, 1983 The final evolution and explosion of stars from 10 M/sub solar/ to 10/sup 6/ M/sub solar/ are reviewed with emphasis on factors affecting the expected nucleosynthesis. We order our paper in a sequence of decreasing mass.

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Nuclear reactions for nucleosynthesis beyond Fe [PDF]
, 2015 Many more nuclear transitions have to be known in the determination of stellar reactivities for trans-iron nucleosynthesis than for reactions of light nuclei. This requires different theoretical and experimental approaches.

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...
