Contribution of spicules to solar coronal emission |
Abstract: Recent high-resolution imaging and spectroscopic observations have generated
renewed interest in spicules' role in explaining the hot corona. Some studies

A reanalysis of the latest SH0ES data for $H_0$: Effects of new degrees of freedom on the Hubble tension |
Abstract: We reanalyze the recently released SH0ES data for the determination of $H_0$.
We focus on testing the homogeneity of the Cepheid+SnIa sample and the
robustness of the results in the presence of new degrees of freedom in the
modeling of Cepheids and SnIa. We thus focus on the four modeling parameters of

Abstract: We derive the equations of motion for an $N$-body system in the
Einstein-Cartan gravity theory at the first post-Newtonian order by exploiting
the Weyssenhoff fluid as the spin model. Our approach consists in performing
the point-particle limit of the continuous description of the gravitational
source. ... | https://export.arxiv.org/pdf/2208.09839 |
