Data pubblicazione: | 2018 | Rivista: | THE ASTROPHYSICAL JOURNAL LETTERS | Numero: | 868 | Fascicolo: | 2 | Da pagina:: | L29 | Abstract: | Based on a theoretical selection of pulsars as candidates for detection at X-ray energies, we present an analysis of archival X-ray observations performed with Chandra and XMM-Newton of PSR J1747-2958 (the pulsar in the “Mouse” nebula), PSR J2021+3651 (the pulsar in the “Dragonfly” nebula), and PSR J1826-1256. X-ray pulsations from PSR J1747-2958 and PSR J1826-1256 are detected for the first time, and a previously reported hint of an X-ray pulsation from PSR J2021+3651 is confirmed with a higher significance. We analyze these pulsars’ spectra in regard to the theoretically predicted energy distribution, finding a remarkable agreement, and provide here a refined calculation of the model parameters taking into account the newly derived X-ray spectral data. | URI: | http://hdl.handle.net/20.500.12386/30278 | URL: | https://iopscience.iop.org/article/10.3847/2041-8213/aae92b | ISSN: | 2041-8205 | DOI: | 10.3847/2041-8213/aae92b | Bibcode ADS: | 2018ApJ...868L..29L | Fulltext: | open |
