Titolo: | IKT16: Discovery of a 22 ms energetic rotation-powered pulsar in the Small Magellanic Cloud | Autori: | Maitra, C. Esposito, P. Tiengo, A. Ballet, J. Haberl, F. Dai, S. Filipovic, M. D. PILIA, Maura |
Data pubblicazione: | 2021 | Rivista: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY. LETTERS | Numero: | 507 | Fascicolo: | 1 | Da pagina:: | L1 | Abstract: | We report here on the discovery with XMM-Newton of pulsations at 22 ms from the central compact source associated with IKT16, a supernova remnant in the Small Magellanic Cloud (SMC). The measured spin period and spin period derivative correspond to 21.7661076(2) ms and $2.9(3)\times10^{-14}$ s,s$^{-1}$, respectively. Assuming standard spin-down by magnetic dipole radiation, the spin-down power corresponds to $1.1\times10^{38}$,erg,s$^{-1}$ implying a Crab-like pulsar. This makes it the most energetic pulsar discovered in the SMC so far and a close analogue of PSR J0537--6910, a Crab-like pulsar in the Large Magellanic Cloud. The characteristic age of the pulsar is 12 kyr. Having for the first time a period measure for this source, we also searched for the signal in archival data collected in radio with the Parkes telescope and in Gamma-rays with the Fermi/LAT, but no evidence for pulsation was found in these energy bands. | URI: | http://hdl.handle.net/20.500.12386/31866 | URL: | https://academic.oup.com/mnrasl/article/507/1/L1/6290506?login=true http://arxiv.org/abs/2105.07779v1 |
