X射线 牛顿天文望远镜 巡天探测器
2023/5/12
近日，国家天文台张彦霞研究员、赵永恒研究员和北京大学吴学兵教授基于中国郭守敬望远镜（LAMOST）和美国斯隆数字巡天(SDSS)的光谱数据，结合欧洲航天局的X射线牛顿天文望远镜（XMM-Newton）数据、广域红外巡天探测器（WISE）数据及SDSS可见光测光数据，通过交叉证认方法获取了具有不同波段信息的多个已知样本。基于此，研究人员通过机器学习方法构建了适合不同波段样本的最优分类器，为X射线牛顿...

Use of requirements engineering within the Thirty Meter Telescope project
TMT system engineering requirements
2015/5/13
The Thirty Meter Telescope is comprised of thirty five individual sub-systems which include optical systems,
instruments, adaptive optics systems, controls, mechanical systems, supporting software a...
Thermal Analysis of the TMT Telescope Structure
telescope structure thermal analysis environment data temperature distributions
2015/5/13
Thermal performances of the Thirty Meter Telescope (TMT) structure were evaluated by finite element thermal models.
The thermal models consist of the telescope optical assembly systems, instruments,...
Thermal modeling environment for TMT
Extremely Large Telescopes Thermal Modeling Computational Fluid Dynamics
2015/5/13
In a previous study we had presented a summary of the TMT Aero-Thermal modeling effort to support thermal seeing
and dynamic loading estimates. In this paper a summary of the current status of Compu...
Systems engineering of the Thirty Meter Telescope through integrated opto-mechanical analysis
telescope structure opto-mechanical modeling
2015/5/13
The merit function routine (MFR) is implemented in the National Research Council Canada Integrated Modeling
(NRCIM) toolset and based in the MATLAB numerical computing environment. It links ANSYS fi...
Primary mirror dynamic disturbance models for TMT: Vibration and wind
Extremely Large Telescopes Wind Vibration Control Systems
2015/5/13
The principal dynamic disturbances acting on a telescope segmented primary mirror are unsteady wind pressure
(turbulence) and narrowband vibration from rotating equipment. Understanding these disturb...
Statistical approach to systems engineering for the Thirty Meter Telescope
Systems engineering Thirty Meter Telescope performance estimate
2015/5/13
Core components of systems engineering are the proper understanding of the top level system requirements, their
allocation to the subsystems, and then the verification of the system built against th...

Investigation of Thirty Meter Telescope Wavefront Maintenance Using Low Order Shack-Hartmann Wavefront Sensors to Correct for Thermally Induced Misalignments
Wavefront Sensing and Control Active Optics On-Instrument Wavefront Sensor
2015/5/13
We evaluate how well the performance of the Thirty Meter Telescope (TMT) can be maintained against thermally
induced errors during a night of observation. We first demonstrate that using look-u...
Normalized Point Source Sensitivity for Off-Axis Optical Performance Evaluation of the Thirty Meter Telescope
Point Source Sensitivity Optical Performance Metric Optical Modeling
2015/5/13
The Normalized Point Source Sensitivity (PSSN) has previously been defined and analyzed as an On-Axis
seeing-limited telescope performance metric. In this paper, we expand the scope of the PSSN...
