TL;DR: In this article, a catalog of modified theories of gravity for which strong-field predictions have been computed and contrasted to Einstein's theory is presented, and the current understanding of the structure and dynamics of compact objects in these theories is summarized.

TL;DR: In this paper, the authors report evidence from multiple satellite measurements that ozone in the lower stratosphere between 60°S and 60°N has indeed continued to decline since 1998, and they find that, even though upper stratospheric ozone is recovering, the continuing downward trend in the upper stratosphere prevails, resulting in a downward trend of ozone between 60 − 90°N and 60 − 80°N.

TL;DR: It is shown that, with existing data, the inverse distance ladder formed from BOSS baryon acoustic oscillation measurements and the Pantheon supernova sample yields an H_{0} posterior near identical to the Planck CMB measurement.

TL;DR: In this paper, the mass distribution of neutron stars in binary systems using a flexible Gaussian mixture model and use Bayesian model selection to explore evidence for multi-modality and a sharp cut-off in the mass distributions.

TL;DR: In this paper, the authors derived the equations of motion, periastron shift, and the gravitational radiation damping for quasicircular compact binaries in a massive variant of the Brans-Dicke theory of gravity.
