论文摘要
CNIA0.02项目旨在收集一个完整的，附近的IA型超新星（SNE IA）光曲线样本，SNE用宿主 - 荷马克大学红移z_host <0.02进行体积限制。主要的科学目标是以完整且公正的方式推断本地SNE IA的关键特性（例如光度函数）的分布，以研究SN爆炸物理学。我们通过光谱对所有Sky自动化的Supernovae（ASAS-SN）检测到的SN候选者进行分类，该调查达到峰值亮度<16.5 mag。由于ASAS-SN扫描了整个天空，并且不瞄准特定的星系，因此我们的目标选择实际上是由宿主 - 果实特性无偏见的。从发现之时开始，我们执行多频段光度观察。在第一个数据发布（DR1）中，我们介绍了从项目中获得的247 SNE获得的光学光曲线（包括完整样本中的148 sne），并得出参数，例如峰通量，dm15和s_bv。
The CNIa0.02 project aims to collect a complete, nearby sample of Type Ia supernovae (SNe Ia) light curves, and the SNe are volume-limited with host-galaxy redshifts z_host < 0.02. The main scientific goal is to infer the distributions of key properties (e.g., the luminosity function) of local SNe Ia in a complete and unbiased fashion in order to study SN explosion physics. We spectroscopically classify any SN candidate detected by the All-Sky Automated Survey for Supernovae (ASAS-SN) that reaches peak brightness < 16.5 mag. Since ASAS-SN scans the full sky and does not target specific galaxies, our target selection is effectively unbiased by host-galaxy properties. We perform multi-band photometric observations starting from the time of discovery. In the first data release (DR1), we present the optical light curves obtained for 247 SNe from our project (including 148 SNe in the complete sample), and we derive parameters such as the peak fluxes, dm15 and s_BV.
