The Age Evolution of the Radio Morphology of Supernova Remnants [PDF]
Astrophysical Journal, 2018 Recent hydrodynamical models of supernova remnants (SNRs) demonstrate that their evolution depends heavily on the inhomogeneities of the surrounding medium.

Magnetic Reconnection Detonation in Supernova Remnants [PDF]
Astrophysical Journal, 2018 As a key process that refreshes the interstellar medium (ISM), the dynamics and radiative properties of the supernova remnant (SNR) expansion front not only reflect the physical environment of the old ISM surrounding the supernova, but they also provide ...

Revised Distances to 21 Supernova Remnants [PDF]
, 2017 We carry out a comprehensive study of H i 21 cm line observations and 13CO line observations of 21 supernova remnants (SNRs). The aim of the study is to search for H i absorption features to obtain kinematic distances in a consistent manner.

Supernova Remnants in the Local Group I: A model for the radio luminosity function and visibility times of supernova remnants [PDF]
, 2016 Supernova remnants (SNRs) in Local Group galaxies offer unique insights into the origin of different types of supernovae. In order to take full advantage of these insights, one must understand the intrinsic and environmental diversity of SNRs in the ...

Journal of Analytical Psychology, Volume 70, Issue 4, Page 616-639, September 2025.Abstract Patricia Berry’s interpretation of the Demeter/Persephone myth, and her concept of rape into consciousness, illuminate intrapsychic dynamics. However, this symbolic lens may inadvertently distance us from the devastating nature of literal rape—a reality the Homeric Hymn encapsulates.

Dynamical Evolution and Radiative Processes of Supernova Remnants [PDF]
, 2017 I outline the dynamical evolution of the shell remnants of supernovae (SNRs), from initial interaction of supernova ejecta with circumstellar material (CSM) through to the final dissolution of the remnant into the interstellar medium (ISM).

A CHANDRA STUDY OF THE INTERSTELLAR METALLICITY IN THE LARGE MAGELLANIC CLOUD USING SUPERNOVA REMNANTS [PDF]
, 2016 We report on the results from our measurements of the interstellar medium (ISM) abundances for the elements O, Ne, Mg, Si, and Fe in the Large Magellanic Cloud (LMC).

Infrared Emission from Supernova Remnants: Formation and Destruction of Dust [PDF]
, 2017 We review the observations of dust emission in supernova rem- nants (SNRs) and supernovae (SNe). Theoretical calculations suggest that SNe, particularly core-collapse, should make significant quantities of dust, perhaps as much as a solar mass ...

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.
