摘要:

首次利用XMM-Newton反射光栅光谱仪(RGS)的多指向模式对明亮的Seyfert 1星系Mrk~509进行了研究,以约束该星系的外流性质。我们希望从具有优异统计质量的Mrk 509的600 ks光谱中获得最准确的光谱特性。我们推导出RGS有效面积的精确相对校准,推导出精确的绝对波长校准,改进了添加时间相关光谱的方法,并将光谱拟合的效率提高了两个数量级。我们的光谱数据质量的主要改善,由于使用新的RGS多点模式的XMM-牛顿。我们说明了增益的准确性,通过显示,与改进的波长校准,在UV光谱中观察到的两个速度槽解决。

英文摘要:

We study the bright Seyfert 1 galaxy Mrk~509 with the Reflection Grating Spectrometers (RGS) of XMM-Newton using the RGS multi-pointing mode of XMM-Newton for the first time in order to constrain the properties of the outflow in this object. We want to obtain the most accurate spectral properties from the 600 ks spectrum of Mrk 509 which has excellent statistical quality. We derive an accurate relative calibration for the effective area of the RGS, derive an accurate absolute wavelength calibration, improve the method for adding time-dependent spectra and enhance the efficiency of the spectral fitting by two orders of magnitude. We show the major improvement of the spectral data quality due to the use of the new RGS multi-pointing mode of XMM-Newton. We illustrate the gain in accuracy by showing that with the improved wavelength calibration the two velocity troughs observed in UV spectra are resolved.
