我们利用SDSS DR 8巡天中位于$z\simeq 0.04-0.1$的$78,340$恒星形成星系样本,计算了星云尘埃的平均衰减曲线及其随星系物理性质的变化。利用前四条低阶巴耳末辐射线(H $α$,H $β$,H $γ$,H $δ$),得到了$0.41\,μ$ m ~ $0.66\,μ$ m范围内的星云衰减曲线,它与银河系消光曲线具有相似的形状和归一化(Milky Way curve)、最近导出的$z\sim2$典型成星星系的SMC曲线和星云衰减曲线。我们将星系划分成恒星质量,气相金属丰度和特定恒星形成率的箱,并推导出这些箱中的星云衰减曲线。这一分析表明,有非常小的变化,在形状的星云尘埃衰减曲线的属性用于bin的星系,并建议一个几乎普遍的形状的星云尘埃衰减曲线至少在星系和我们的样本中考虑的属性范围。
英文摘要:
We use a sample of $78,340$ star-forming galaxies at $z\simeq 0.04-0.1$ from the SDSS DR8 survey to calculate the average nebular dust attenuation curve and its variation with the physical properties of galaxies. Using the first four low-order Balmer emission lines (H$α$, H$β$, H$γ$, H$δ$) detected in the composite spectrum of all galaxies in the sample, we derive a nebular attenuation curve in the range of $0.41\,μ$m to $0.66\,μ$m that has a similar shape and normalization to that of the Galactic extinction curve (Milky Way curve), the SMC curve and the nebular attenuation curve derived recently for typical star-forming galaxies at $z\sim2$. We divide the galaxies into bins of stellar mass, gas-phase metallicity, and specific star-formation rate, and derive the nebular attenuation curve in each of these bins. This analysis indicates that there is very little variation in the shape of the nebular dust attenuation curve with the properties used to bin the galaxies, and suggests a near universal shape of the nebular dust attenuation curve at least among the galaxies and the range of properties considered in our sample.

He II Emission from Wolf-Rayet Stars as a Tool for Measuring Dust Reddening
我们校准了一种测量恒星形成星系中尘埃衰减的技术。该技术利用沃尔夫-拉叶星的星风线,这是广泛观察到的星系光谱。He II 1640和4686的特征是复合线,其比例在很大程度上由原子物理学决定。因此,它们可以作为恒星尘埃探测器,就像巴耳末线被用作星云探测器一样。我们测量了银河系和大麦云云中97颗沃尔夫-拉叶星的He II 1640谱线强度。红化校正通量遵循紧密的相关性与固定的比率为7.76的He II 1640至4686线比。尘埃衰减降低了这个比率。我们提供了恒星E(B-V)和几个衰减规律的观测线比之间的关系。结合这种技术与使用的星云巴耳末衰减允许的恒星和星云尘埃衰减星系的测定,并可以探测其在不同的恒星年龄和质量制度的影响,独立于初始质量函数和恒星形成的历史。我们推导出尘埃红化的He II线通量,并将其与Balmer衰减和两个恒星形成星系中紫外线连续谱斜率的红化进行了比较。这三种方法产生的粉尘衰减在误差范围内一致。未来的应用,这种技术允许研究的恒星尘埃衰减相比,星云衰减在一个有代表性的星系样本。

Stellar Absorption Line Analysis of Local Star-Forming Galaxies: The Relation Between Stellar Mass, Metallicity, Dust Attenuation and Star Formation Rate
Reproducing the UVJ Color Distribution of Star-forming Galaxies at 0.5 < z < 2.5 with a Geometric Model of Dust Attenuation
我们分析了0.5 < z < 2.5时恒星形成星系的静止坐标系U-V和V-J色的分布。使用恒星星族合成,随机恒星形成的历史,和一个简单的处方的尘埃衰减,占星系的形状和倾角,我们构建了一个模型的星系颜色的分布。只有两个自由参数,这个模型能够再现观测到的星系的颜色作为一个函数的红移和恒星质量非常好。我们的分析表明,在给定的红移和恒星质量下,恒星形成星系的尘埃衰减值范围很广,几乎完全是由于倾斜的影响;如果所有星系都被观察到,它们将显示出非常相似的尘埃衰减。这一结果具有重要意义的解释尘埃衰减测量,紫外和红外光度的治疗,数值模拟和观测之间的比较。
