TeV gamma rays from Galactic objects pulsars pulsar nebulae and supernova remnants

چکیده
Pulsar nebula supernova remnant and nu cleus of active galaxy are found as TeV gamma ray emit ter and the number of such sources is now approaching All of them so far evidenced are explained by electron progenitor The emission process in the TeV energy region is characterized and controlled by the particle interaction of high energy photons and electrons The radiation by electrons implies a tight link of emission in the TeV re gion to the other bands raising importance of the multi wavelengths analysis in order to investigate production acceleration and interaction of energetic particles The ab soption of TeV gamma rays due to pair creation of elec tron and positron becomes more serious for smaller size of emission region The constraint on the emission size is discussed and found consistent with the VHE sources so far discovered The point like source of gamma rays by proton progenitor still remains to be uncovered

On the Evolution of the Γ- and X-ray Luminosities of Pulsar Wind Nebulae
Pulsar wind nebulae are a prominent class of very high energy (E > 0.1 TeV) Galactic sources. Their γ-ray spectra are interpreted as due to inverse Compton scattering of ultrarelativistic electrons on the ambient photons, whereas the X-ray spectra are due to synchrotron emission. We investigate the relation between the γand-X-ray emission and the pulsars’ spin-down luminosity and characteristic...
متن کاملMillisecond pulsar population in the Galactic center and high energy contributions
We propose that there possibly exists a population of millisecond pulsars in the Galactic center region. Millisecond pulsars (MSPs) could emit GeV gamma-rays through synchrotron-curvature radiation as predicted by outer gap models. In the same time, the compact wind nebulae around millisecond pulsars can emit X-rays though synchrotron radiation and TeV photons through inverse Compton processes....
متن کاملObservations of Supernova Remnants and Pulsar Wind Nebulae: A VERITAS Key Science Project
The study of supernova remnants and pulsar wind nebulae was one of the Key Science Projects for the first two years of VERITAS observations. VERITAS is an array of four imaging Cherenkov telescopes located at the Whipple Observatory in southern Arizona. Supernova remnants are widely considered to be the strongest candidate for the source of cosmic rays below the knee at around 10 eV. Pulsar win...
متن کاملOBSERVATIONS OF PULSARS , PSR 1509 − 58 AND PSR 1259 − 63 , BY CANGAROO 3 . 8 m TELESCOPE
The data for VHE (∼TeV) gamma rays from young gamma-ray pulsar PSR1509-58 observed in 1996 with the CANGAROO 3.8mČerenkov imaging telescope are presented, as well as the additional data from March to June of 1997. The high spin-down luminosity of the pulsar and the plerionic feature around the pulsar observed with radio and X-rays suggest that VHE gamma-ray emission is quite likely above the se...
متن کاملRecent VERITAS Results on Galactic Supernova Remnants and Pulsar Wind Nebula
Supernova remnants (SNR) and pulsar wind nebulae (PWN) are among the most numerous of TeV-emitting objects in the sky and provide excellent laboratories for the investigation of high-energy particle acceleration in astrophysical environments. In many cases, their relative proximity to earth and resultant large angular sizes allow for detailed mapping of emission regions and precise correlations...
