The Growth of Structure in Interacting Dark Energy Models [PDF]

, 2009
If dark energy interacts with dark matter, there is a change in the background evolution of the universe, since the dark matter density no longer evolves as a^{-3}. In addition, the non-gravitational interaction affects the growth of structure.

Identification and persistence mechanism of very small glaciers and perennial snow patches in the northern Japanese Alps

Frontiers in Earth Science
In this study, we measure ice thickness and flow and reveal that Shakushizawa and Kaerazuzawa perennial snow patches (PSPs) in the northern Japanese Alps are glaciers instead. Due to their size, they are very small glaciers (VSGs).

Volcanic eruptions from ghost magma chambers [PDF]

, 2008
Recent studies have proposed that magma reservoirs crystallized to a virtually rigid crystal-mush can be partially remelted by diffusion of hot fluids. We show that for a crystal mush with the composition of a K-trachyte from the Campanian Ignimbrite (CI)

Early successional changes in coniferous forest small mammal communities following a high‐severity summer wildfire

Ecosphere
Forest fires in the southern Rocky Mountains are changing due to climate warming and increased fuel loads. Landscape‐scale stand‐replacement fires create extensive treeless swaths without regenerative seed sources, leading to long‐term conversion of ...

Insights Into the Eruptive Dynamics of Small Caldera-Forming Eruptions: The Case Study of the Welded Scoriae of Vulcano (Aeolian Islands, Italy)

Frontiers in Earth Science, 2020
A multi-disciplinary study, integrating volcanological field observations, petrography, whole rock geochemistry and textural and compositional analyses on plagioclase crystals has been carried out on the products of Monte Luccia, Spiaggia Lunga, and ...

Rapid caldera subsidence and fluctuating eruption dynamics: the lithostratigraphy and structure of the Loch Bà Caldera, Isle of Mull, NW Scotland

Volcanica
Caldera-forming eruptions represent extremely hazardous events. The Loch Bà Caldera on the Isle of Mull, NW Scotland, preserves an ~120 m thick sequence of Palaeogene silicic pyroclastic rocks and collapse breccias.

Structures controlling volcanic activity within Masaya caldera, Nicaragua

Volcanica, 2019
Geophysical and geological observations collected in 2007-2012 shed light on the mechanisms controlling the style and location of eruptions within the Las Sierras-Masaya Caldera complex, Nicaragua.

Geological, geophysical, and geochemical constraints on the time-space evolution of Akan composite caldera, Hokkaido, Japan

Frontiers in Earth Science, 2022
Some calderas are geometrically complex that may be related not to a single eruption, magma body, or structure. In order to reveal their forming processes, multidisciplinary methods should be applied.
