Gauge versus (hidden) physical symmetries of FLRW cosmologies
Journal of High Energy PhysicsIn generally covariant theories, evolution in coordinate time is a gauge transformation, so that a symmetry made manifest in a gauge-fixed description need not be a symmetry of the physical dynamics.

Late Antique Allāh: Ancestral Arabian Religion and the Monotheistic Zeitgeist
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT This essay addresses the ongoing scholarly tension between the monotheistic interpretations of late pre‐Islamic Arabian religion, pioneered by G. Hawting and P. Crone, and the traditional accounts of rampant Arabian polytheism found in later Islamic literary sources.

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial
Archaeometry, EarlyView.ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Inferring the cosmological constant in early Universe only by gravitational waves
Journal of High Energy PhysicsGravitational waves (GWs) from compact binary coalescence (CBC) can directly determine the luminosity distance but usually can not obtain information about the redshift. This assumes that the GW source is at the flat background.

Growth factor in teleparallel Gauss-Bonnet gravity
Physics Letters BTeleparallel gravity offers a competing geometric framework on which to build cosmological models. The Gauss-Bonnet invariant captures key aspects of the underlying geometry that has been shown to be an interesting way to form cosmological models beyond ...

, 2019 A cosmological model is proposed. In the model, vacuum energy is converted into positive mass and the mass grows exponentially with more vacuum energy conversion up to $1.758144 \times 10^{53}~ [kg]$ when it stops after $9.76317 \times 10^{-14}~[s]$. During this period of mass increase the quanta form a condensate Bose-Einstein.

Geomagnetic Intensity of Hellenistic Pottery and Stamped Rhodian Wine Amphorae From Jerusalem
Archaeometry, EarlyView.ABSTRACT Stamped amphora handles produced on Rhodes during the Hellenistic period are well suited for archaeointensity studies because they often bear the names of annually appointed magistrates (eponyms) and fabricants, allowing dating to narrow time intervals.

Testing the Standard Cosmological Model [PDF]
, 2011 This thesis exploits the wealth of information contained in the existing cosmological surveys, and demonstrates how the use of tools such as two-point statistics permit the extraction of such information.

Cluster algebras for cosmological correlators
Journal of High Energy PhysicsIn this paper,we explore the cluster algebras for symbol letters or singularities of cosmological correlators in a conformally coupled scalar field theory. We show that the symbol letters for tree-level n-site ladder cosmological correlators are governed

Boreas, EarlyView.The Dinaric Mountains are a mountain range stretching NW–SE from the Alps to the Albanides–Hellenides in central Europe. The highest parts were occupied by small ice fields and/or valley glaciers during the Quaternary cold periods, while even today some small glaciers still exist in topoclimatically favourable areas.
