Shot noise and reconstruction of the acoustic peak

, 2010
We study the effect of noise in the density field, such as would arise from a finite number density of tracers, on reconstruction of the acoustic peak within the context of Lagrangian perturbation theory.

Kepler’s problem of a two-body system perturbed by a third body

The European Physical Journal Plus
One of the most important problems in basic physics and astronomy is studying the motion of planets, satellites, and other celestial bodies. The solution to the two-body problem enables astronomers to predict the orbits of the Moon, satellites, and ...

Generating Stable and Metastable Critical Points in Uncertain Systems via Flow‐Based Models

Expert Systems, Volume 43, Issue 3, March 2026.
ABSTRACT This work proposes the use of conditional flow‐based generative models to learn an approximation of the distribution of the critical points of a cost function. This approximation is used to incrementally identify all critical points, in the feasible domain of said function, by iteratively alternating the sampling of the distribution and the ...

The Cycles and Dynamical Properties of Convective Outbreaks in Jupiter's Highest Speed Jet From a 55‐Year Study

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...

The Influence of Deep Space and the Stars on Emotions

International Journal of Psychology, Volume 61, Issue 1, February 2026.
ABSTRACT Detailed photographs of deep space from the James Webb telescope are public, yet little is known about how such imagery might affect people. Using both face‐to‐face and online study designs, compared to exposure to photographs of urban environments, exposure to photographs of deep space and stars increased experiences of awe overall and also ...

Mesh, Hydrodynamic Boundary, and Uncertainty Analysis of the 2D‐SWEs: Taking Numerical Simulation of River Networks as an Example

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Targeting the issues of insufficient predictive ability and inefficient computation in two‐dimensional shallow water equations (2D‐SWEs), this study deeply couples the mesh and hydrodynamic boundary, constructing multiple 2D hydrodynamic models (run 2,640 times).

Interpreting Changes in Global Methane Budget in a Chemistry‐Climate Model Constrained With Methane and Isotopic Observations

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The continuous increase in atmospheric methane (CH4) concentrations over the past few decades has become a major concern due to its strong role as a greenhouse gas contributing to climate change. In this work, we investigate the changes in the global methane budget using a global chemistry‐climate model constrained with methane and its ...

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Effective sound speed in relativistic accretion discs around rotating black holes

, 2019
For axially symmetric accretion maintained in the hydrostatic equilibrium along the vertical direction in the Kerr metric, the radial Mach number does not become unity at the critical point.

Runoff Reconstructions and Future Projections Indicate Highly Variable Water Supply From Pacific Rim Water Towers

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Anthropogenic climate change affects regional hydrological cycles and poses significant challenges to the sustainable supply of freshwater. The Central China water tower (CCWT) is the key source region feeding the Yangtze and Yellow Rivers, and its runoff is indispensable for the surrounding mega‐city clusters. Here we present a reconstruction
