A Pulsar Wind Nebula in the Oxygen-Rich Supernova Remnant G292.0+1.8

Abstract

Using the Chandra X-ray Observatory we have discovered a diffuse, center-filled region of hard X-ray emission within the young, oxygen-rich supernova remnant (SNR) G292.0+1.8. Near the peak of this diffuse emission lies a point-like source of X-ray emission that is well described by an absorbed power-law spectrum with photon index $1.72\pm 0.09$. This source appears to be marginally extended; its extent of 1.3${}^{\prime \prime }$ (FWHM) is greater than that of a nearby serendipitous X-ray source with FWHM = $1.1^{\prime \prime }$. This is strong evidence for the presence within SNR G292.0+1.8 of a young rapidly-rotating pulsar and its associated pulsar wind nebula. From the unabsorbed, 0.2-4 keV band X-ray luminosity of the pulsar wind nebula ($L_X\sim 4\times 10^{34}\mathrm{ergs}{\mathrm{s}}^{-1}$), we infer a spin-down energy loss rate of $\dot{E}\sim 7\times 10^{36}\mathrm{ergs}{\mathrm{s}}^{-1}$ for the still undetected pulsar. The pulsar candidate is $0.9^{\prime }$ from the geometric center of the SNR which implies a transverse velocity of $\sim$$770(D/4.8\mathrm{kpc})(t/1600\mathrm{yr}{)}^{-1}\mathrm{km}{\mathrm{s}}^{-1}$ assuming currently accepted values for the distance and age of G292.0+1.8.
