Abstract

We report the discovery of PSR J1101–6101, a 62.8 ms pulsar in IGR J11014–6103, a hard X-ray source with a jet and a cometary tail that strongly suggests it is moving away from the center of the supernova remnant (SNR) MSH 11–61A at v > 1000 km s{sup –1}. Two XMM-Newton observations were obtained with the EPIC pn in small window mode, resulting in the measurement of its spin-down luminosity E-dot =1.36×10{sup 36} erg s{sup –1}, characteristic age τ {sub c} = 116 kyr, and surface magnetic field strength B{sub s} = 7.4 × 10{sup 11} G. In comparison to τ {sub c}, the 10-30 kyr age estimated for MSH 11–61A suggests that the pulsar was born in the SNR with initial period in the range 54 ≤ P {sub 0} ≤ 60 ms. PSR J1101–6101 is the least energetic of the 15 rotation-powered pulsars detected by INTEGRAL, and has a high efficiency of hard X-ray radiation and jet power. We examine the shape of the cometary nebula in a Chandra image, which is roughly consistent with a bow shock at the velocity inferred from the SNR age and the pulsar's E-dot . However, its structure differs in detail from the classic bow shock,more »« less

IS IGR J11014-6103 A PULSAR WITH THE HIGHEST KNOWN KICK VELOCITY?

Journal Article Tomsick, John; Bodaghee, Arash; Fornasini, Francesca; ... - Astrophysical Journal Letters

We report on Chandra X-ray and Parkes radio observations of IGR J11014-6103, which is a possible pulsar wind nebula with a complex X-ray morphology and a likely radio counterpart. With the superb angular resolution of Chandra, we find evidence that a portion of the extended emission may be related to a bow shock due to the putative pulsar moving through the interstellar medium. The inferred direction of motion is consistent with IGR J11014-6103 having been born in the event that produced the supernova remnant (SNR) MSH 11-61A. If this association is correct, then previous constraints on the expansion of MSHmore »« less

DISCOVERY OF A HIGHLY ENERGETIC PULSAR ASSOCIATED WITH IGR J14003-6326 IN THE YOUNG UNCATALOGED GALACTIC SUPERNOVA REMNANT G310.6-1.6

Journal Article Renaud, M; Marandon, V; Terrier, R; ... - Astrophysical Journal

We report the discovery of 31.18 ms pulsations from the INTEGRAL source IGR J14003-6326 using the Rossi X-ray Timing Explorer (RXTE). This pulsar is most likely associated with the bright Chandra X-ray point source lying at the center of G310.6-1.6, a previously unrecognized Galactic composite supernova remnant (SNR) with a bright central non-thermal radio and X-ray nebula, taken to be the pulsar wind nebula (PWN). PSR J1400-6325 is amongst the most energetic rotation-powered pulsars in the Galaxy, with a spin-down luminosity of E-dot = 5.1x10{sup 37} erg s{sup -1}. In the rotating dipole model, the surface dipole magnetic field strengthmore »« less

DISCOVERY OF AN ENERGETIC 38.5 ms PULSAR POWERING THE GAMMA-RAY SOURCE IGR J18490-0000/HESS J1849-000

Journal Article Gotthelf, E; Halpern, J; Terrier, R; ... - Astrophysical Journal Letters

We report the discovery of a 38.5 ms X-ray pulsar in observations of the soft {gamma}-ray source IGR J18490-0000 with the Rossi X-ray Timing Explorer (RXTE). PSR J1849-0001 is spinning down rapidly with period derivative 1.42 x 10{sup -14} s s{sup -1}, yielding a spin-down luminosity E-dot = 9.8 x 10{sup 36} erg s{sup -1}, characteristic age {tau}{sub c}{identical_to}P/2 P-dot = 42.9 kyr, and surface dipole magnetic field strength B{sub s} = 7.5 x 10{sup 11} G.

XMM-NEWTON OBSERVATIONS OF TWO CANDIDATE SUPERNOVA REMNANTS

Journal Article Kargaltsev, O; Schmitt, B; Pavlov, G; ... - Astrophysical Journal

Candidate supernova remnants (SNRs) G23.5+0.1 and G25.5+0.0 were observed by XMM-Newton in the course of a snapshot survey of plerionic and composite SNRs in the Galactic plane. In the field of G23.5+0.1, we detected an extended source, {approx}3' in diameter, which we tentatively interpret as a pulsar wind nebula (PWN) of the middle-aged radio pulsar B1830-08 (J1833-0827; P = 85.3 ms, {tau} = 147 kyr, E-dot = 5.8 Multiplication-Sign 10{sup 35} erg s{sup -1}, d = 5.7 kpc), with the PWN luminosity L{sub 0.2-10keV} Almost-Equal-To 5 Multiplication-Sign 10{sup 33} erg s{sup -1} Almost-Equal-To 8 Multiplication-Sign 10{sup -3} E-dot .

OUT OF THE FRYING PAN: A YOUNG PULSAR WITH A LONG RADIO TRAIL EMERGING FROM SNR G315.9-0.0

Journal Article Camilo, F; Ng, C; Gaensler, B; ... - Astrophysical Journal (Online)

The faint radio supernova remnant SNR G315.9-0.0 is notable for a long and thin trail that extends outward perpendicular from the edge of its approximately circular shell. In a search with the Parkes telescope, we have found a young and energetic pulsar that is located at the tip of this collimated linear structure. PSR J1437-5959 has period P = 61 ms, characteristic age tau{sub c}=P/(2P-dot)=114 kyr, and spin-down luminosity E-dot=1.4 x 10{sup 36} erg s{sup -1}. It is very faint, with a flux density at 1.4 GHz of about 75 muJy. From its dispersion measure of 549 pc cm{sup -3},more »« less
