利用SDSS Data Release 15公开提供的阿帕奇点天文台(MANGA)绘制附近星系图的数据分析管道(DAP)产品，分析了不同类型SN主星系在SN爆发点的局部性质和全球性质，以探索不同类型SNE的爆炸环境。在我们的样本中，漫画视野中有67个SN宿主星系，包括32个Ia型星系，29个核坍缩SNE星系(CCSNe)，1个超光速星系(SLSN)，1个I型SNE星系和4个未分类的SNE星系。我们可以应用K-S检验进行分析，并得出统计上稳健的结果。由于样本量有限，我们无法消除这项工作中的质量相关性，这可能是这项工作中呈现的属性趋势的真正驱动因素。SNIa主机的全球恒星形成率和EW(Hα)平均略低于CCSN主机。Sn Ia主星系的质量比CcSn主星系大0.3倍，这意味着随着主星系恒星质量的增加，CcSNe与Ia型Sne的数量比将减小.Sn Ia主星系的恒星群年龄比Ccn主星系的平均年龄要大。不同类型的SN宿主之间在某些性质上没有显著差异，包括局部SFR密度(ΣSFR)以及局部和全球气相氧气丰度。对于我们的样本中的大多数星系，从SN主机的积分光谱估计的全球气相氧丰度可以用小偏差来表示SN爆炸地点的局部气相氧丰度。
By using Data Analysis Pipeline (DAP) products of Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), which are publicly available from the SDSS Data Release 15, we analyze the local properties at the SN explosion sites and global properties of different types of SN host galaxies to explore the explosion environments of different types of SNe. In our sample, there are 67 SN host galaxies in the field of view of MaNGA, including 32 Type Ia, 29 core collapse SNe (CCSNe), 1 superluminous SN (SLSN), 1 Type I and 4 unclassified type of SNe, with which we can apply the K-S test for analysis and derive statistically robust results. Due to the limited sample size, we could not remove the mass dependence in this work, which is likely the true driver of the trends for the properties presented in this work. The global star formation rate (SFR) and EW(Hα) for SN Ia hosts are slightly lower than those for CCSN hosts on average. SN Ia host galaxies are ∼0.3 dex more massive than CCSN hosts, which implies that the number ratio of CCSNe to Type Ia SNe will decrease with increasing stellar mass of host galaxies. The stellar population age of SN Ia host galaxies is older than that of CCSN hosts on average. There is no significant difference between different types of SN hosts for some properties, including local SFR density (ΣSFR), and local and global gas-phase oxygen abundance. For most galaxies in our sample, the global gas-phase oxygen abundance estimated from the integrated spectra of SN hosts can represent the local gas-phase oxygen abundance at the SN explosion sites with small bias.
