Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Characterization of Mass Wasting Events on Lunar Maria Using Mini‐RF Radar Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Evidence of mass wasting has been observed on the Moon since at least the Apollo era. Surface features indicative of mass wasting processes are traditionally characterized geomorphologically using visible images. In this study, we aim to better understand mass wasting features via their radar properties, which can provide insights into the ...

Observational Test of f(Q) Gravity with Weak Gravitational Lensing

The Astrophysical Journal
In this article we confront a class of f ( Q ) gravity models with observational data of galaxy–galaxy lensing. Specifically, we consider f ( Q ) gravity models containing a small quadratic correction when compared with general relativity (GR), and ...

Weak gravitational lensing cross-correlations

, 2017
The matter content of the Universe is dominated by dark matter. Beyond its abundance and its lack of non-gravitational interactions with standard model matter, little is known about the nature of dark matter. This thesis attempts to illuminate different aspects of dark matter by using gravitational lensing in conjunction with other cosmological probes.

Hydrological and Thermal Dynamics of a Supra‐Permafrost Subterranean Estuary

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Subterranean estuaries (STEs), where groundwater interacts with seawater, influence surface and subsurface coastal ecology and biogeochemistry. In Arctic‐STEs overlying permafrost, groundwater flow and heat transport determine the fate of organic matter.

PlumeDEBuG: Data‐Informed Modeling for Synthetic Bubble Plume Image Generation

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Bubble plumes play an important role in both natural and engineered aquatic systems. Optical imaging has been widely used to study bubble size distributions, meandering, and plume growth. Machine learning (ML) offers new opportunities in analyzing optical images of bubble plumes.

Alternative estimators for weak gravitational lensing

, 2012
Weak gravitational lensing provides a means to measure the total mass in the Universe. The incoming light from distant galaxies is disturbed by the inhomogeneity of the dark matter distribution along the line of sight. The correlations of shape in an observed galaxy population can be used to probe the total mass density fluctuations in the Universe ...
