Discovery of a New Quasar: SDSS J022155.26-064916.6
摘要：
我们报告发现了一个新的类星体：SDSS J022155.26-064916.6。这个天体是在减少恒星样本的光谱时发现的，这些恒星被认为是暗能量调查的分光光度标准。给出了流量和波长校准谱，并确定了四条谱线。从这些线，红移被确定为z约等于0.806。此外，用代理类星体的合成光度学获得的k-校正确定的静止坐标系u-、g-和r-波段光度分别报告为7.496 $\times 10^{13}$太阳光度、2.049 $\times 10^{13}$太阳光度和$1.896 \times 10^{13}$太阳光度。
英文摘要：
We report the discovery of a new quasar: SDSS J022155.26-064916.6. This object was discovered while reducing spectra of a sample of stars being considered as spectrophotometric standards for the Dark Energy Survey. The flux and wavelength calibrated spectrum is presented with four spectral lines identified. From these lines, the redshift is determined to be z is approximately equal to 0.806. In addition, the rest-frame u-, g-, and r-band luminosity, determined using a k-correction obtained with synthetic photometry of a proxy QSO, are reported as 7.496 $\times 10^{13}$ solar luminosities, 2.049 $\times 10^{13}$ solar luminosities, and $1.896 \times 10^{13}$ solar luminosities, respectively.
