The 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...
متن کاملTeV 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 کاملA high resolution UV absorption spectrum of supernova ejecta in SN 1006
We report a high resolution, far-ultraviolet, STIS E140M spectrum of the strong, broad Si II, III, and IV features produced by the ejecta of SN1006 seen in absorption against the background Schweizer-Middleditch star. The spectrum confirms the extreme sharpness of the red edge of the redshifted Si II 1260 Å feature, supporting the idea that this edge represents the location of the reverse shock...
متن کاملSeparating Thermal and Nonthermal X - Rays in Supernova Remnants I : Total Fits to SN 1006 AD
The remnant of SN 1006 has an X-ray spectrum dominated by nonthermal emission , and pre-ASCA observations were well described by a synchrotron calculation with electron energies limited by escape. We describe the results of a much more stringent test: fitting spatially integrated ASCA GIS (0.6 – 8 keV) and RXTE PCA (3 – 10 keV) data with a combination of the synchrotron model sresc newly ported...
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...
