Jet-driven bubbles in Fanaroff-Riley type I sources
Christopher M. Irwin, Xiaping Tang, Tsvi Piran +1
Observations of several Fanaroff-Riley (FR) type I sources reveal outflowing bipolar bubbles of hot gas surrounded by a weak forward shock. We consider the possibility that these b…
The deepest Chandra X-ray study of the plerionic supernova remnant G21.50.9
Benson Guest, Samar Safi-Harb, Xiaping Tang
G21.5-0.9 is a plerionic supernova remnant (SNR) used as a calibration target for the Chandra X-ray telescope. The first observations found an extended halo surrounding the bright…
Positron flux and gamma-ray emission from Geminga pulsar and pulsar wind nebula
Xiaping Tang, Tsvi Piran
Nearby pulsars have been suggested as sources of TeV Cosmic Ray (CR) excess on Earth. The High-Altitude Water Cherenkov Observatory (HAWC) detected extended TeV emi…
NuSTAR Detection of a Hard X-ray Source in the Supernova Remnant - Molecular Cloud Interaction Site of IC 443
Shuo Zhang, Xiaping Tang, Xiao Zhang +10
We report on a broadband study of a complex X-ray source (1SAX J0618.0+2227) associated with the interaction site of the supernova remnant (SNR) IC 443 and ambient molecular cloud…
Similarity of -ray spectrum in middle aged supernova remnants (SNRs) interacting with molecular clouds (MC): what can we learn?
Xiaping Tang
In this work, we compare the -ray spectra available in literature from 11 middle aged supernova remnants (SNRs) interacting with molecular clouds (MCs). It is found that 5 remna…
Gamma-ray emission from middle-aged supernova remnants interacting with molecular clouds: the challenge for current models
Xiaping Tang
We compare the -ray spectra from 10 middle-aged supernova remnants (SNRs), which are interacting with molecular clouds (MCs), with the model prediction from widely used escaping…
Time dependent diffusive shock acceleration and its application to middle aged supernova remnants
Xiaping Tang, Roger A. Chevalier
Recent gamma-ray observations show that middle aged supernova remnants (SNRs) interacting with molecular clouds (MCs) can be sources of both GeV and TeV emission. Based on the MC a…
Shock evolution in non-radiative supernova remnants
Xiaping Tang, Roger A. Chevalier
We present a new analytical approach to derive approximate solutions describing the shock evolution in non-radiative supernova remnants (SNRs). We focus on the study of the forward…
Time-dependent Diffusive Shock Acceleration in Slow Supernova Remnant Shocks
Xiaping Tang, Roger A. Chevalier
Recent gamma ray observations show that middle aged supernova remnants interacting with molecular clouds can be sources of both GeV and TeV emission. Models involving re-accelerati…
Gamma-Ray Emission from Supernova Remnant Interaction with Molecular Clumps
Xiaping Tang, Roger A. Chevalier
Observations of the middle-aged supernova remnants IC 443, W28 and W51C indicate that the brightnesses at GeV and TeV energies are correlated with each other and with regions of mo…
Particle Transport in Young Pulsar Wind Nebulae
Xiaping Tang, Roger A. Chevalier
The model for pulsar wind nebulae (PWNe) as the result of the magnetohydrodynamic (MHD) downstream flow from a shocked, relativistic pulsar wind has been successful in reproducing…
