The soft γ-ray pulsar population: a high-energy overview.


Abstract (from CDS):

At high-energy γ-rays (>100 MeV), the Large Area Telescope (LAT) on the Fermi satellite already detected more than 145 rotation-powered pulsars (RPPs), while the number of pulsars seen at soft γ-rays (20keV-30 MeV) remained small. We present a catalogue of 18 non-recycled RPPs from which presently non-thermal pulsed emission has been securely detected at soft γ-rays above 20keV, and characterize their pulse profiles and energy spectra. For 14 of them, we report new results, (re)analysing mainly data from RXTE, INTEGRAL, XMM-Newton and Chandra. The soft γ-pulsars are all fast rotators and on average ∼ 9.3 times younger and ∼ 43 times more energetic than the Fermi LAT sample. The majority (11 members) exhibits broad, structured single pulse profiles, and only six have double (or even multiple, Vela) pulses. 15 soft γ-ray pulsar show hard power-law spectra in the hard X-ray band and reach maximum luminosities typically in the MeV range. For only 7 of the 18 soft γ-ray pulsars, pulsed emission has also been detected by the LAT, but 12 have a pulsar wind nebula (PWN) detected at TeV energies. For six pulsars with PWNe, we present also the spectra of the total emissions at hard X-rays, and for IGR J18490-0000, associated with HESS J1849-000 and PSR J1849-0001, we used our Chandra data to resolve and characterize the contributions from the point source and PWN. Finally, we also discuss a sample of 15 pulsars which are candidates for future detection of pulsed soft γ-rays, given their characteristics at other wavelengths.
