We study the effect of filter zero-point uncertainties on future supernova dark energy missions. Fitting for calibration parameters using simultaneous analysis of all Type Ia supernova standard candles achieves a significant improvement over more traditional fit methods. This conclusion is robust under diverse experimental configurations (number of observed supernovae, maximum survey redshift, inclusion of additional systematics). This approach to supernova fitting considerably eases otherwise stringent mission calibration requirements. As an example we simulate a space-based mission based on the proposed JDEM satellite; however the method and conclusions are general and valid for any future supernova dark energy mission, ground or space-based.
Cosmology Requirements on Supernova Photometric Redshift Systematics for Rubin LSST and Roman Space Telescope
在即将到来的广域时域调查中，将发现和监测大约100万颗Ia型超新星（SN），如Vera C。Rubin Observatory Legacy Survey of Space and Time（鲁宾天文台时空遗产巡天）对于宇宙学的应用，除了其他特性外，还需要精确的红移;然而绝大多数SN不会有光谱红移，即使是对于它们的宿主星系，也只有光度红移。我们评估了红移系统控制必要的强大的宇宙学。基于由机器学习产生的光度与真实红移关系，应用于LSST质量观察到的50万个星系的模拟，我们量化了平均关系和异常值分数和偏差中的系统学要求，以便不偏向暗能量宇宙学推断。某些红移范围是特别敏感的，激发了SN在$z\lesssim0.2$和$z\approx0.5$-0.6附近的光谱跟踪。包括Nancy Grace Roman太空望远镜近红外波段的模拟中，我们重新分析的约束，发现在高红移的改善，但很少在低红移的系统学导致强烈的宇宙学偏见。我们确定了一个完整的光谱调查SN主机星系$z\lesssim0.2$作为一个非常有利的元素强大的SN宇宙学。
The Extended Hubble Space Telescope Supernova Survey: The Rate of Core Collapse Supernovae to z~1
We use a sample of 45 core collapse supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope to derive the core collapse supernova rate in the redshift range 0.1<z<1.3. In redshift bins centered on <z>=0.39, <z>=0.73, and <z>=1.11, we find rates 3.00 {+1.28}{-0.94}{+1.04}{-0.57}, 7.39 {+1.86}{-1.52}{+3.20}{-1.60}, and 9.57 {+3.76}{-2.80}{+4.96}{-2.80}, respectively, given in units yr^{-1} Mpc^{-3} 10^{-4} h_{70} ^3. The rates have been corrected for host galaxy extinction, including supernovae missed in highly dust enshrouded environments in infrared bright …
The value of the Hubble-Lemaître constant queried by Type Ia Supernovae: A journey from the Calán-Tololo Project to the Carnegie Supernova Program
我们评估的鲁棒性的两个最高的梯级的“宇宙距离阶梯”的Ia型超新星和哈勃-勒梅特常数的测定。在这个分析中，我们保持固定的朗格1作为到LMC的距离，使用分离双星确定为1%。对于Rung 2，我们分析了两种方法，TRGB和造父变星的距离在附近星系的Ia型超新星的光度校准。对于Rung 3，我们分析了哈勃流中的各种现代数字超新星样本，如Calán-Tololo，CfA，CSP和Supercal数据集。该元数据分析表明，TRGB校准产生的$H_0$值小于Cepheid校准，这是这两种方法校准的距离模量系统差异的直接结果。选择三个最独立的可能的方法/带通（$B$，$V$，$J$），我们获得$H_{0}=69.9 \pm 0.8$和$H_{0} =73.5 \pm 0.7$ km s $^{-1}$ Mpc $^{-1}$从TRGB和Cepheid校准，分别。分别在1.1和1.0 km s $^{-1}$ Mpc $^{-1}$的TRGB和Cepheid方法中添加正交系统不确定性，该子集揭示了在Rung 2校准中的显著2.0 $σ$系统差异。如果Rung 1和Rung 2保持不变，那么为标准化超新星峰值星等而开发的不同形式会产生一致的结果，标准偏差为1.5 km s $^{-1}$ Mpc $^{-1}$，也就是说，Ia型超新星能够以2%的精度锚定Rung 3。这项研究表明，Ia型超新星提供了超…
