Spitzer spectral line mapping of supernova remnants. I. Basic data and principal component analysis
Molecules Abundances
2014/12/23
We report the results of spectroscopic mapping observations carried out toward small (1' × 1') regions within the supernova remnants W44, W28, IC 443, and 3C 391 using the Infrared Spectrograph (IRS) ...
SUPERNOVA REMNANTS AND THE INTERSTELLAR MEDIUM OF M83: IMAGING AND PHOTOMETRY WITH THE WIDE FIELD CAMERA 3 ON THE HUBBLE SPACE TELESCOPE
supernova star-forming galaxy M83
2014/12/20
We present Wide Field Camera 3 images taken with the Hubble Space Telescope within a single field in the southern grand design star-forming galaxy M83. Based on their size, morphology, and photometry ...
A Study of Optical Observing Techniques for Extra-Galactic Supernova Remnants: Case of NGC 300
Optical Observing Techniques Extra-Galactic Supernova Remnants NGC 300
2012/2/21
We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC 300. The goal...
A Sino-German $λ$6\ cm polarization survey of the Galactic plane VI. Discovery of supernova remnants G178.2-4.2 and G25.1-2.3
supernova remnants – ISM: individual objects: G178.2− 4.2, G25.1− 2.3 – Radio continuum: ISM
2011/9/27
Supernova remnants (SNRs) were often discovered in radio surveys of the Galactic plane. Because of the surface-brightness limit of previous surveys, more faint or confused SNRs await discovery. The Si...
Using the X-ray Morphologies of Young Supernova Remnants to Constrain Explosion Type, Ejecta Distribution, and Chemical Mixing

2010/11/10
Supernova remnants (SNRs) are a complex class of sources, and their heterogeneous nature has
hindered the characterization of their general observational properties. To overcome this challenge,in thi...
Spitzer observations of supernova remnants: II. Physical conditions and comparison with HH7 and HH54

2010/11/9
We have studied the shock-excited molecular regions associated with four supernova remnants (SNRs) — IC443C, W28, W44 and 3C391 — and two Herbig-Haro objects,HH7 and HH54, using Spitzer ’s Infrared Sp...
Neutrino emission of Fermi supernova remnants

2010/12/28
The Fermi $\gamma$-ray space telescope reported the observation of several Galactic supernova remnants recently, with the $\gamma$-ray spectra well described by hadronic $pp$ collisions. The possible ...
