The detection of GW170817, the first neutron starneutron star merger observed by Advanced LIGO and Virgo, and its following analyses represent the first contributions of gravitational wave data to understanding dense matter. Parameterizing the high density section of the equation of state of both neutron stars through spectral decomposition, and imposing a lower limit on the maximum mass value, led to an estimate of the stars’ radii of
The waveform of a compact binary coalescence is predicted by general relativity. It is therefore possible to directly constrain the response of a gravitationalwave (GW) detector by analyzing a signal’s observed amplitude and phase evolution as a function of frequency. GW signals alone constrain the relative amplitude and phase between different frequencies within the same detector and between different detectors. Furthermore, if the source’s distance and inclination can be determined independently, for example from an electromagnetic (EM) counterpart, one can calibrate the absolute amplitude response of the detector network. We analyze GW170817’s ability to calibrate the LIGO/Virgo detectors, finding a relative amplitude calibration precision of approximately

Abstract In Mediterraneantype climates, asynchronicity between energy and water availability means that ecosystems rely heavily on the waterstoring capacity of the subsurface to sustain plant water use over the summer dry season. The rootzone water storage capacity (
[L]) defines the maximum volume of water that can be stored in plant accessible locations in the subsurface, but is poorly characterized and difficult to measure at large scales. Here, we develop an ecohydrological modeling framework to describe how ${S}_{\mathrm{m}\mathrm{a}\mathrm{x}}$ mediates root zone water storage ( ${S}_{\mathrm{m}\mathrm{a}\mathrm{x}}$S [L]), and thus dry season plant water use.more » 
Abstract We construct, for the first time, the timedomain gravitational wave strain waveform from the collapse of a strongly gravitating Abelian Higgs cosmic string loop in full general relativity. We show that the strain exhibits a large memory effect during merger, ending with a burst and the characteristic ringdown as a black hole is formed. Furthermore, we investigate the waveform and energy emitted as a function of string width, loop radius and string tension
Gμ . We find that the mass normalized gravitational wave energy displays a strong dependence on the inverse of the string tensionE _{GW}/M _{0}∝ 1/Gμ , with at the percent level, for the regime where ${E}_{\text{GW}}/{M}_{0}\sim \mathcal{O}(1more\xbb$Gμ ≳ 10^{−3}. Conversely, we show that the efficiency is only weakly dependent on the initial string width and initial loop radii. Using these results, we argue that gravitational wave production is dominated by kinematical instead of geometrical considerations. 
Abstract The stratospheric influence on summertime high surface ozone (
) events is examined using a twentyyear simulation from the Whole Atmosphere Community Climate Model. We find that ${\mathrm{O}}_{3}$ transported from the stratosphere makes a significant contribution to the surface ${\mathrm{O}}_{3}$ variability where background surface ${\mathrm{O}}_{3}$ exceeds the 95 ${\mathrm{O}}_{3}$th percentile, especially over western U.S. Maximum covariance analysis is applied to anomalies paired with stratospheric ${\mathrm{O}}_{3}$ tracer anomalies to identify the stratospheric intrusion and the underlying dynamical mechanism. The first leading mode corresponds to deep stratospheric intrusions inmore » ${\mathrm{O}}_{3}$ 
Abstract Chiral and helical Majorana fermions are two archetypal edge excitations in twodimensional topological superconductors. They emerge from systems of different Altland–Zirnbauer symmetries and characterized by
and $\mathbb{Z}$ topological invariants respectively. It seems improbable to tune a pair of copropagating chiral edge modes to counterpropagate in a single system without symmetry breaking. Here, we explore the peculiar behaviors of Majorana edge modes in topological superconductors with an additional ‘mirror’ symmetry which changes the bulk topological invariant to ${\mathbb{Z}}_{2}$ type. A theoretical toy model describing the proximity structure of a Chern insulator andmore » $\mathbb{Z}\oplus \mathbb{Z}$
