TeV emission from SN 1006
Supernova 1006 is the first shell type super-nova remnant to show evidence of particle acceleration to TeV energies. In the present paper we examine this possibility by modeling the observed X-ray non-thermal emission in terms of synchrotron radiation from Fermi accelerated electrons. The predicted synchrotron spectrum fits the radio and non-thermal component of the observed soft X-ray to hard ...
متن کاملThe Historical Supernovae
The available historical records of supernovae occurring in our own Galaxy over the past two thousand years are reviewed. These accounts include the well-recorded supernovae of AD 1604 (Kepler’s SN), 1572 (Tycho’s SN), 1181, 1054 (which produced the Crab Nebula) and 1006, together with less certain events dating back to AD 185. In the case of the supernovae of AD 1604 and 1572 it is European re...
متن کاملOn the origin of TeV radiation of SN 1006
We discuss the link between the nonthermal X-radiation and TeV γ-ray emission from SN 1006, and study the capabilities of both electronic and nucleonic models for explanation of the TeV flux observed from the northeast rim of SN 1006. We show that the interpretation of the TeV radiation by the inverse Compton scattering of electrons on 2.7 K cosmic microwave background radiation is possible, ho...
متن کاملSpatial structure of X - ray filaments in SN 1006
The theory of non-linear diffusive shock acceleration (NLDSA) predicts the formation of a precursor upstream of the shock, where accelerated particles diffuse and induce magnetic field amplification (MFA) through streaming instability. The non-detection of this precursor in X-rays in Chandra observations of the north-eastern region of SN 1006 (G329.6+14.6) led the authors of some previous work ...
متن کاملThe Optical Spectrum of the Sn 1006 Supernova Remnant Revisited
We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the NW rim of SN 1006. We detect the broad and narrow components of Hα, Hβ and Hγ and report the first detection of the He I λ 6678 emission line in this supernova remnant. We may have detected, at the 1.5σ level, faint He II λ4686 emission. We measure a full width half maximum of 2290± 80 km s in the broad c...
