The Barycentric Region of the Local Group: Present Extent, Membership Dependence, and Uncertainty Growth

The Local Group (LG) barycentre is used as a kinematic reference in studies of LG dynamics, but the uncertainty in its inferred position and its dependence on theadopted galaxy membership are not always quantified together. We propagate observationally motivated uncertainties for...

The Stellar Death Clock: Thermodynamic Constrains on Civilizational Survival

This work proposes a thermodynamically constrained framework for interpreting the Fermi Paradox. Rather than attributing the absence of detectable extraterrestrial civilizations solely to sociological or self-destructive Great Filters, the study explores the possibility that stel...
