Infrared Ejecta and Cold Dust in the Young Supernova Remnant N132D [PDF]
The Astrophysical Journal, 2023 We present Spitzer, Wide-field Infrared Survey Explorer (WISE), and Herschel observations of the young supernova remnant (SNR) N132D in the Large Magellanic Cloud, including 3–40 μ m Spitzer Infrared Spectrograph (IRS) mapping, 12 μ m WISE and 70, 100 ...

Impact Ejecta near the Impact Point Observed using Ultra-high-speed Imaging and SPH Simulations, and a Comparison of the Two Methods [PDF]
, 2020 High-speed impact ejecta at velocities comparable to the impact velocity are expected to contribute to material transport between planetary bodies and deposition of ejecta far from the impact crater.

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

GRB 060206: hints of precession of the central engine? [PDF]
2008A&A...487..503, 2008 Aims. The high-redshift (z=4.048) gamma-ray burst GRB 060206 showed unusual behavior, with a significant rebrightening by a factor of ~4 at about 3000 s after the burst. We argue that this rebrightening implies that the central engine became active again

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 ...

Linking Analytic Light-curve Models to Physical Properties of Kilonovae [PDF]
The Astrophysical JournalIn binary neutron star mergers, lanthanide-rich dynamical ejecta and lanthanide-poor postmerger ejecta have often been linked to red and blue kilonova emission, respectively.

Circumstellar ejecta around LBV’s [PDF]
International Astronomical Union Colloquium, 1989 AbstractThe properties of circumstellar shells around LBV’s are reviewed. Some LBV’s are surrounded by very extended nebulosities, similar to classical planetary nebulae, with AG Car as the prototype. The masses of these nebulae are of the order of a solar mass and their kinematic ages are about 104years.

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.
