We present a detailed X-ray and radio wavelength study of G308.4-1.4, a candidate supernova remnant (SNR) in the ROSAT All Sky Survey and the MOST supernova remnant catalogue.
Classifying structures in the ISM with Support Vector Machines: the G16.05-0.57 supernova remnant
Classifying structures Support Vector Machines supernova remnant
2011/10/20
We apply Support Vector Machines -- a machine learning algorithm -- to the task of classifying structures in the Interstellar Medium. As a case study, we present a position-position velocity data cube...

Modeling the Multi-Wavelength Emission of Shell-Type Supernova Remnant RX J1713.7-3946
Modeling the Multi-Wavelength Emission Shell-Type Supernova Remnant
2010/11/9
Emission mechanisms of the shell-type supernova remnant (SNR) RX J1713.7-3946 are studied with multi-wavelength observational data from radio, X-ray,GeV γ-ray to TeV γ-ray band. A Markov Chain Monte C...
Modeling of the Vela complex including the Vela supernova remnant, the binary system gamma2 Velorum, and the Gum nebula
ISM supernova remnants – ISM clouds – ISM bubbles – ISM individual objects Vela SNR shock waves Stars
2010/11/11
We study the geometry and dynamics of the Vela complex including the Vela supernova remnant (SNR), the binary system γ2 Velorum and the Gum nebula. We show that the Vela SNR belongs to a subclass of n...
Investigating the Cosmic-Ray Ionization Rate Near the Supernova Remnant IC 443 Through H3+ Observations
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
Observational and theoretical evidence suggests that high-energy Galactic cosmic rays are primarily accelerated by supernova remnants. If also true for low-energy cosmic rays, the ionization rate near...
The Role of Diffusive Shock Acceleration on Nonequilibrium Ionization in Supernova Remnant Shocks II: Emitted Spectra
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the hydrodynamics of the ...
Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke (Nature, 462, 71 (2009)) that the thermal radiation of this star is well-d...
A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：II. THE CASE OF VARIABLE TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
In this preliminary report a modification of the theoretical Σ − D
relation for supernova remnants (SNRs) in the adiabatic expansion phase is presented
in another way. As in Paper I, this modi...
A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：I. THE CASE OF CONSTANT TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
We present a modification of the theoretical Σ − D relation for
supernova remnants (SNRs) in the adiabatic expansion phase. This modification
is based on the convolution of the relation first ...
