A geophysical investigation of the Roter Kamm impact crater, Namibia
Meteoritics &Planetary Science, EarlyView.Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

The Evolution of Hetergeneous "Clumpy Jets": A Parameter Study
, 2011 We investigate the role discrete clumps embedded in an astrophysical jet play on the jet's morphology and line emission characteristics. By varying clumps' size, density, position, and velocity, we cover a range of parameter space motivated by ...

VSOP observation of the quasar PKS 2215+020: a new laboratory for core-jet physics at z=3.572 [PDF]
, 2000 We report results of a VSOP (VLBI Space Observatory Programme) observation of a high redshift quasar PKS 2215+020 (z=3.572). The ~1 milliarcsecond resolution image of the quasar reveals a prominent `core-jet' structure on linear scales from 5/h to 300/h ...

Hydrodynamic Simulations of Astrophysical Jets [PDF]
Proceedings of XII Multifrequency Behaviour of High Energy Cosmic Sources Workshop — PoS(MULTIF2017), 2018 {We present recent results of our three-dimensional (3-D) simulations of astrophysical jets. These efforts use the the PLUTO code (Mignone \textit{et al. 2007}) run in a highly parallel environment for the hydrodynamic, magneto-hydrodynamic (MHD), relativistic hydrodynamic (RHD), and relativistic, magnetohydrodynamic (RMHD) simulations.

Seasonal Ice Cover Could Allow Liquid Lakes to Persist in a Cold Mars Paleoclimate
AGU Advances, Volume 7, Issue 1, February 2026.Abstract Geomorphic and stratigraphic studies of Mars prove that extensive liquid water flowed and pooled on the surface early in Mars' history. Martian paleoclimate models, however, have difficulty simulating climate conditions warm enough to maintain liquid water on early Mars.

A Search for Consistent Jet and Disk Rotation Signatures in RY Tau [PDF]
, 2015 We present a radial velocity study of the RY Tau jet-disk system, designed to determine whether a transfer of angular momentum from disk to jet can be observed.

AGU Advances, Volume 7, Issue 1, February 2026.Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...
