五个TeV超新星的射电和X射线观测

Radio and X-ray observations of Five TeV SNRs

Wenwu Tian, Denis Leahy

摘要:

我们简要地总结了最近的结果,从无线电和X射线观测的五个TeV信噪比。本文重点对5 TeV信噪比HESS J1732-347/SNR G353.6-0.7的运动学距离进行了重新测量(3.2 kpc),HESS J1834-087/G23.3-0.3(同样为W 41,4.0 kpc),HESS J1833-105/G21.5-0.9(4.8 kpc),HESS J1846-029/G29.7-0.3(Kes 75,6.3 kpc)和TeV SNR G54.1-0.3(6.5 kpc),并研究两个旧SNR(G353.6-0.7和W 41)的非热X射线发射。这不仅可以约束TeV信噪比的基本物理性质,而且有助于揭示TeV伽马射线在信噪比中的加速机制,这些机制要么与信噪比有关,要么与脉冲星风星云有关。

英文摘要:

We briefly summarize recent results of five TeV SNRs from radio and X-ray observations. We focus on remeasuring kinematic distances of 5 TeV SNRs, i.e. HESS J1732-347/SNR G353.6-0.7 (3.2 kpc), HESS J1834-087/G23.3-0.3 (also W41, 4.0 kpc), HESS J1833-105/G21.5-0.9 (4.8 kpc), HESS J1846-029/G29.7-0.3 (Kes 75, 6.3 kpc) and TeV SNR G54.1-0.3 (6.5 kpc), and studying non-thermal X-ray emissions from two old SNRs (G353.6-0.7 and W41). These not only allow constraining the TeV SNR basic physical properties, but also help reveal acceleration mechanisms of TeV Gamma-rays in the SNRs which are either related with the SNRs or the pulsar wind nebulae.
