The Moderate Cooling Flow Model and Feedback in Galaxy Formation

, 2009
For the recent four years we have been studying feedback heating in cooling flow (CF) clusters by AGN activity that inflate bubbles by jets; this short contribution to a meeting summarizes our main results.

Synchronized Eruptions on Io: Possible Evidence of Interconnected Subsurface Magma Reservoirs

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract On 27 December 2024, Juno's JIRAM (Jovian InfraRed Auroral Mapper) instrument observed an unprecedented volcanic event in Io's southern hemisphere, covering a vast region of ∼65,000 km2, near 73°S, 140°E. Within the imaged region, only one hot spot was previously known (Pfd454).

Particle acceleration in electron-ion jets

, 2005
Weibel instability created in collisionless shocks is responsible for particle (electron, positron, and ion) acceleration. Using a 3-D relativistic electromagnetic particle (REMP) code, we have investigated particle acceleration associated with a ...

Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

Formation and Alteration of Olivine‐Carbonate Rocks Within Jezero Crater as Constrained by In Situ Visible/Near‐Infrared Multispectral Images

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Olivine‐ and carbonate‐bearing rocks are key exploration targets on Mars because of the information they can provide about magma evolution and source characteristics, implications for surface water availability and climate, and their biosignature preservation potential.

An Energy Perspective of Core Erosion in Gas Giant Planets

The Astrophysical Journal Letters
Juno and Cassini have shown that Jupiter and Saturn likely contain extended gradients of heavy elements. Yet, how these gradients can survive over billions of years remains an open question.

Making Observed and Modeled Martian Dust Storm Trajectories Visible Using a New Automatic Tracking Algorithm

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Dust in the atmosphere of Mars, along with its radiative effects, is the central factor for understanding the Martian climate. Global circulation models and remote sensing observations are used to shed light on the evolution of Martian dust storms.
