High angular resolution gravitational wave astronomy [PDF]

Experimental astronomy (Print), 2019
Since the very beginning of astronomy the location of objects on the sky has been a fundamental observational quantity that has been taken for granted.

A Numerical 3D‐2D Coupling Strategy for Simulating Landslide‐Generated Tsunamis in Complex Geometries: The Taan Fiord, Alaska, Case Study

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Landslide‐generated tsunamis represent a significant hazard, specifically in coastal, fjord, and lake environments. The accurate modeling of these complicated phenomena is crucial for risk assessment and preparation of mitigation strategies.

Unsupervised Machine Learning for Classifying CHIME Fast Radio Bursts and Investigating Empirical Relations

The Astrophysical Journal
Fast radio bursts (FRBs) are highly energetic millisecond-duration astrophysical phenomena typically categorized as repeaters or nonrepeaters. However, observational limitations may result in misclassifications, potentially leading to a higher proportion

Matching Matched Filtering with Deep Networks for Gravitational-Wave Astronomy. [PDF]

Physical Review Letters, 2017
We report on the construction of a deep convolutional neural network that can reproduce the sensitivity of a matched-filtering search for binary black hole gravitational-wave signals.

Probing Jupiter's Atmosphere Through Juno Radio Occultations: Analysis of the Atmospheric Thermal Structure

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The upper layers of Jupiter's atmosphere, offering critical insights into the planet's deeper structure, are accessible through radio occultation experiments. Since July 2023, NASA's Juno extended mission has provided the first high‐resolution radio occultation measurements since the Voyager era, probing the thermal structure and composition ...

Equiaffine Braneworld

Galaxies, 2020
Higher dimensional theories, wherein our four dimensional universe is immersed into a bulk ambient, have received much attention recently, and the directions of investigation had, as far as we can discern, all followed the ordinary Euclidean hypersurface

Deep Follow-up for Gravitational-wave Inference: A Case Study with GW151226

The Astrophysical Journal, 2023
New analyses of gravitational-wave events raise questions about the nature of some events. For example, LIGO–Virgo–KAGRA initially determined GW151226 to be a merger with a mass ratio q ≈ 0.5 and effective inspiral spin χ _eff ≈ 0.2.

Label switching problem in Bayesian analysis for gravitational wave astronomy [PDF]

Physical Review D, 2019
The label switching problem arises in the Bayesian analysis of models containing multiple indistinguishable parameters with arbitrary ordering. Any permutation of these parameters is equivalent, therefore models with many such parameters have extremely ...

Spectral Analysis of the Morphology of Fresh Lunar Craters II: Two‐Dimensional Surface Elevations of the Continuous Ejecta, Wall, and Floor

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The morphology of fresh lunar craters provides important clues about how craters of different sizes form, and is used as a baseline for understanding how craters evolve over time. Topographic spectral analysis is a powerful tool for studying the morphology of lunar craters, as it can quantify the scale‐dependent topographic variation of ...

Multi-optimization for thermal deformation of gravitational wave telescope based on CFRP characteristics

Scientific Reports
Gravitational wave telescope place extremely high demands on structural thermal deformation, making material selection a critical issue. Carbon fiber reinforced polymer (CFRP) is an ideal choice for the support structure of telescope due to its low ...
