We present Chandra X-ray Observatory archival observations of the supernova remnant 1E0102.2-7219, a young oxygen-rich remnant in the Small Magellanic Cloud. Combining 28 ObsIDs for 324ks of total exposure time, we present an Advanced CCD Imaging Spectrometer image with an unprecedented signal-to-noise ratio (mean S/N √S ∼ 6; maximum S/N > 35). We search within the remnant, using the source detection software WAVDETECT, for point sources which may indicate a compact object. Despite finding numerous detections of high significance in both broad and narrowband images of the remnant, we are unable to satisfactorily distinguish whether these detections correspond to emission from a compact object. We also present upper limits to the luminosity of an obscured compact stellar object which were derived from an analysis of spectra extracted from the high signal-to-noise image. We are able to further constrain the characteristics of a potential neutron star for this remnant with the results of the analysis presented here, though we cannot confirm the existence of such an object for this remnant.
