Abstract
Using the Parkes Radio Telescope, we have carried out deep observations of 11 unassociated gamma‐ray sources. Periodicity searches of these data have discovered two millisecond pulsars, PSR J1103−5403 (1FGL J1103.9−5355) and PSR J2241−5236 (1FGL J2241.9−5236), and a long‐period pulsar, PSR J1604−44 (1FGL J1604.7−4443). In addition, we searched for but did not detect any radio pulsations from six gamma‐ray pulsars discovered by the Fermi satellite to a level of ∼0.04 mJy (for pulsars with a 10 per cent duty cycle). The timing of the millisecond pulsar PSR J1103−5403 has shown that its position is 9 arcmin from the centroid of the gamma‐ray source. Since these observations were carried out, independent evidence has shown that 1FGL J1103.9−5355 is associated with the flat spectrum radio source PKS 1101−536. It appears certain that the pulsar is not associated with the gamma‐ray source, despite the seemingly low probability of a chance detection of a radio millisecond pulsar. We consider that PSR J1604−44 is a chance discovery of a weak, long‐period pulsar and is unlikely to be associated with 1FGL J1604.7−4443. PSR J2241−5236 has a spin period of 2.2 ms and orbits a very low mass companion with a 3.5‐h orbital period. The relatively high flux density and low dispersion measure of PSR J2241−5236 make it an excellent candidate for high precision timing experiments. The gamma rays of 1FGL J2241.9−5236 have a spectrum that is well modelled by a power law with an exponential cut‐off, and phase binning with the radio ephemeris results in a multipeaked gamma‐ray pulse profile. Observations with Chandra have identified a coincident X‐ray source within 0.1 arcsec of the position of the pulsar obtained by radio timing.

observations of 11 unassociated gamma‐ray sources. Periodicity searches of these data have discovered two millisecond pulsars, PSR J1103−5403 (1FGL J1103.9−5355) and PSR J2241−5236 (1FGL J2241.9−5236), and a long‐period pulsar, PSR J1604−44 (1FGL J1604.7−4443). In addition, we searched for but did not detect any radio pulsations from six gamma‐ray pulsars discovered by the Fermi satellite to a level of ∼0.04 mJy (for pulsars with a 10 per cent duty cycle). The timing of the millisecond pulsar PSR J1103−5403 has shown that its position is 9 arcmin from the centroid of the gamma‐ray source. Since these observations were carried out, independent evidence has shown that 1FGL J1103.9−5355 is associated with the flat spectrum radio source PKS 1101−536. It appears certain that the pulsar is not associated with the gamma‐ray source, despite the seemingly low probability of a chance detection of a radio millisecond pulsar. We consider that PSR J1604−44 is a chance discovery of a weak, long‐period pulsar and is unlikely to be associated with 1FGL J1604.7−4443. PSR J2241−5236 has a spin period of 2.2 ms and orbits a very low mass companion with a 3.5‐h orbital period. The relatively high flux density and low dispersion measure of PSR J2241−5236 make it an excellent candidate for high precision timing experiments. The gamma rays of 1FGL J2241.9−5236 have a spectrum that is well modelled by a power law with an exponential cut‐off, and phase binning with the radio ephemeris results in a multipeaked gamma‐ray pulse profile. Observations with Chandra have identified a coincident X‐ray source within 0.1 arcsec of the position of the pulsar obtained by radio timing.</div></front></TEI><istex><corpusName>wiley</corpusName><keywords><teeft><json:string>pulsar</json:string><json:string>1fgl</json:string><json:string>fermi</json:string><json:string>abdo</json:string><json:string>mnras</json:string><json:string>photon</json:string><json:string>unassociated</json:string><json:string>msps</json:string><json:string>parkes</json:string><json:string>ephemeris</json:string><json:string>monthly notices</json:string><json:string>pulse peak</json:string><json:string>1fgl catalogue</json:string><json:string>unassociated sources</json:string><json:string>arcmin</json:string><json:string>radio timing</json:string><json:string>gamma rays</json:string><json:string>radio pulsations</json:string><json:string>parkes radio telescope</json:string><json:string>spectral analysis</json:string><json:string>radio searches</json:string><json:string>spectrum radio source</json:string><json:string>circular polarization</json:string><json:string>total intensity</json:string><json:string>spectral parameters</json:string><json:string>pulse frequency</json:string><json:string>binary motion</json:string><json:string>millisecond pulsars</json:string><json:string>orbital period</json:string><json:string>flux density</json:string><json:string>energy bins</json:string><json:string>cordes lazio</json:string><json:string>proper motion</json:string><json:string>deep observations</json:string><json:string>radio pulsars</json:string><json:string>radio observations</json:string><json:string>cent arcmin</json:string><json:string>radio position</json:string><json:string>variability analysis</json:string><json:string>monthly light curve</json:string><json:string>acceleration range</json:string><json:string>centre</json:string><json:string>rare objects</json:string><json:string>galactic pulsar population</json:string><json:string>period distribution</json:string><json:string>phase binning</json:string><json:string>right ascension</json:string><json:string>rotation measure</json:string><json:string>australia telescope</json:string><json:string>clock correction procedure</json:string><json:string>system ephemeris model</json:string><json:string>density limit</json:string><json:string>naval research laboratory</json:string><json:string>energy loss</json:string><json:string>point sources</json:string><json:string>electron density</json:string><json:string>other sources</json:string><json:string>energetic pulsars</json:string><json:string>gammaray source 1fgl</json:string><json:string>region round</json:string><json:string>fermi satellite</json:string><json:string>thick line</json:string><json:string>linear polarization</json:string><json:string>upper panel</json:string><json:string>polarization position angles</json:string><json:string>energy range</json:string><json:string>instrument response functions</json:string><json:string>diffuse emission components</json:string><json:string>1fgl sources</json:string><json:string>spectral model</json:string><json:string>likelihood ratio test</json:string><json:string>nasa goddard space flight center</json:string><json:string>spectral index</json:string><json:string>independent evidence</json:string><json:string>santa cruz</json:string><json:string>gammaray source</json:string><json:string>cent arcsec</json:string><json:string>count rate</json:string><json:string>istituto nazionale</json:string><json:string>steady source</json:string><json:string>excellent candidate</json:string><json:string>cent level</json:string><json:string>mass function</json:string><json:string>minimum companion mass</json:string><json:string>high precision timing experiments</json:string><json:string>periodicity searches</json:string><json:string>spectral shapes</json:string><json:string>photon index</json:string><json:string>effective area</json:string><json:string>least digits</json:string><json:string>pulsation</json:string></teeft></keywords><author><json:item><name>M.

Periodicity searches of these data have discovered two millisecond pulsars, PSR J1103−5403 (1FGL J1103.9−5355) and PSR J2241−5236 (1FGL J2241.9−5236), and a long‐period pulsar, PSR J1604−44 (1FGL J1604.7−4443). In addition, we searched for but did not detect any radio pulsations from six gamma‐ray pulsars discovered by the Fermi satellite to a level of ∼0.04 mJy (for pulsars with a 10 per cent duty cycle). The timing of the millisecond pulsar PSR J1103−5403 has shown that its position is 9 arcmin from the centroid of the gamma‐ray source. Since these observations were carried out, independent evidence has shown that 1FGL J1103.9−5355 is associated with the flat spectrum radio source PKS 1101−536. It appears certain that the pulsar is not associated with the gamma‐ray source, despite the seemingly low probability of a chance detection of a radio millisecond pulsar. We consider that PSR J1604−44 is a chance discovery of a weak, long‐period pulsar and is unlikely to be associated with 1FGL J1604.7−4443. PSR J2241−5236 has a spin period of 2.2 ms and orbits a very low mass companion with a 3.5‐h orbital period. The relatively high flux density and low dispersion measure of PSR J2241−5236 make it an excellent candidate for high precision timing experiments. The gamma rays of 1FGL J2241.9−5236 have a spectrum that is well modelled by a power law with an exponential cut‐off, and phase binning with the radio ephemeris results in a multipeaked gamma‐ray pulse profile. Observations with Chandra have identified a coincident X‐ray source within 0.1 arcsec of the position of the pulsar obtained by radio timing.</abstract><subject lang="en"><genre>keywords</genre><topic>pulsars: general</topic><topic>pulsars: individual: J2241−5236</topic></subject><relatedItem type="host"><titleInfo><title>Monthly Notices of the Royal Astronomical Society</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><identifier type="ISSN">0035-8711</identifier><identifier type="eISSN">1365-2966</identifier><identifier type="DOI">10.1111/(ISSN)1365-2966</identifier><identifier type="PublisherID">MNR</identifier><part><date>2011</date><detail type="volume"><caption>vol.</caption><number>414</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>1292</start><end>1300</end><total>9</total></extent></part></relatedItem><identifier type="istex">1964A26FA641ED7CF1D4DB5264DB117359A1C26C</identifier><identifier type="ark">ark:/67375/WNG-WHGSQC5V-D</identifier><identifier type="DOI">10.1111/j.1365-2966.2011.18464.x</identifier><identifier type="ArticleID">MNR18464</identifier><accessCondition type="use and reproduction" contentType="copyright">© 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS</accessCondition><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-L0C46X92-X">wiley</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/1964A26FA641ED7CF1D4DB5264DB117359A1C26C/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
