The formation of planetary disks and winds: an ultraviolet view

, 2008
Planetary systems are angular momentum reservoirs generated during star formation. This accretion process produces very powerful engines able to drive the optical jets and the molecular outflows.

Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions. However, these processes do not always produce surface manifestations and may sometimes elude detection by current geological and geodetic monitoring.

The Wisconsin Plasma Astrophysics Laboratory

, 2015
The Wisconsin Plasma Astrophysics Laboratory (WiPAL) is a flexible user facility designed to study a range of astrophysically relevant plasma processes as well as novel geometries that mimic astrophysical systems. A multi-cusp magnetic bucket constructed

Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within the accretionary wedge. The mechanics of these shallow rupture phenomena and their dependence

Particle Astrophysics and Cosmology: Cosmic Laboratories for New Physics (Summary of the Snowmass 2001 P4 Working Group)

, 2002
The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. Here we summarize some

Redefining SAR Arc Generation: The Competing Roles of Magnetospheric and Ionospheric Energy Injection

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Stable auroral red (SAR) arcs are luminous subauroral emissions produced by the collisional excitation of oxygen atoms during geomagnetically active times. While traditionally attributed to inner magnetospheric electron heating, recent observations and simulations challenge the exclusivity of this mechanism.

Powering AGNs with super-critical black holes

, 2009
We propose a novel mechanism for powering the central engines of Active Galactic Nuclei through super-critical (type II) black hole collapse. In this picture, ~$10^3 M_\odot$ of material collapsing at relativistic speeds can trigger a gravitational shock,

Toward Co‐Designed Earth System Models: Reflecting End‐User Priorities in Local Applications From a Modeler's Perspective

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Earth System Models (ESM) are crucial for quantifying climate impacts across Earth's interconnected systems and supporting science‐based adaptation and mitigation. However, not including end‐users, especially decision‐makers representing communities vulnerable to climate change, can limit model utility, increase epistemic risks, and lead to ...

Why Hydrological Memory Dominates in Low‐Latitude Highlands: A Mechanistic Shift in Ecosystem Response to Extremes

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Understanding how compound extremes affect terrestrial ecosystems is a major challenge in Earth system science. Although the combined effects of stressors are recognized, the manner in which the prestress state determines the basic response mechanism remains unclear.

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract With its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole of Venus has been expected to separate from the figure pole in response to mantle flow ...
