Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion [PDF]
Advanced ScienceCavitation bubbles generated by laser absorption in liquids collapse violently, producing high‐speed jets, toroidal bubbles, and shock waves that induce material erosion and object displacement.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Comparison of Topographic Roughness of Layered Deposits on Mars
Remote Sensing, 2023 Impact craters with layered ejecta deposits are widespread on Mars. Prevailing views suggest that such ejecta were formed due to the involvement of target water and/or water ice in the impact excavation and/or the post-deposition movement of the impact ...

XMM-Newton Large Program on SN1006 - II: Thermal Emission [PDF]
, 2016 Based on the XMM-Newton large program on SN1006 and our newly developed spatially resolved spectroscopy tools (Paper~I), we study the thermal emission from ISM and ejecta of SN1006 by analyzing the spectra extracted from 583 tessellated regions dominated

X-ray ejecta kinematics of the Galactic core-collapse supernova remnant G292.0+1.8 [PDF]
, 2014 We report on the results from the analysis of our 114 ks Chandra HETGS observation of the Galactic core-collapse supernova remnant G292.0+1.8. To probe the 3D structure of the clumpy X-ray emitting ejecta material in this remnant, we measured Doppler ...

Forbush Decrease Characteristics in a Magnetic Cloud
Space Weather, 2020 Based on the new mechanism, the Forbush decrease characteristics are calculated for eight magnetic cloud types. It is shown that the Forbush decrease amplitude does not depend on the magnetic cloud type, while the anisotropy strongly does.

Trans-Ejecta High-Energy Neutrino Emission from Binary Neutron Star Mergers [PDF]
, 2018 The observations of a macronova/kilonova accompanied by gravitational waves from a binary neutron star merger (GW170817) confirmed that neutron star coalescences produce copious ejecta.

Initial 40Ar‐39Ar Ages of the Paleocene‐Eocene Boundary Impact Spherules
Geophysical Research Letters, 2019 We report 40Ar‐39Ar step‐heating ages of Paleocene‐Eocene (P‐E) boundary impact spherules from Atlantic Margin coastal plain and open ocean sites. We test the hypothesis that the P‐E spherules are reworked from an earlier event (e.g., K‐Pg impact at ~66 ...

Hydrodynamic modelling of ejecta shrapnel in the Vela supernova remnant [PDF]
, 2013 Many supernova remnants (SNRs) are characterized by a knotty ejecta structure. The Vela SNR is an excellent example of remnant in which detached clumps of ejecta are visible as X-ray emitting bullets that have been observed and studied in great detail ...
