标题： The Tremaine-Weinberg method at high redshift

摘要： 本文研究了Tremaine-Weinberg（TW）方法在高红移下测量棒旋星系的图案速度的可靠性。在高红shift测量图案速度可能有助于揭示星系棒与暗物质晕之间相互作用的时间演化。TW方法已被广泛用于邻近星系，其在确定棒状图案速度方面的准确性已通过数值模拟得到验证。对于邻近星系，当星系的倾斜角和棒的方位角处于适当的范围内时，该方法可以得到可接受的结果。然而，在观测和模拟中，TW方法在高红移星系中的应用仍尚未被探索。在本研究中，我们从TNG50宇宙学模拟中生成了棒旋星系的模拟观测。这些模拟观测旨在模仿詹姆斯·韦布空间望远镜（JWST）上的近红外光谱仪（NIRSpec）在红移为$z\simeq 1.2$时会捕捉到的积分场单元（IFU）光谱数据。通过将TW方法应用于这些模拟观测，并将结果与已知的图案速度进行比较，我们证明了对于在高红移下能被JWST检测到的足够长的棒旋星系，TW方法表现良好。这项工作为将TW方法应用于研究高红移棒旋星系的特性开辟了一条新途径。 显示英文摘要

摘要： This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redshift may help to shed light on the time evolution of interactions between galactic bars and dark matter halos. The TW method has been extensively employed for nearby galaxies, and its accuracy in determining bar pattern speeds has been validated through numerical simulations. For nearby galaxies, the method yields acceptable results when the inclination angle of the galaxy and the position angle of the bar fall within appropriate ranges. However, the application of the TW method to high-redshift galaxies remains unexplored in both observations and simulations. In this study, we generate mock observations of barred galaxies from the TNG50 cosmological simulation. These simulated observations are tailored to mimic the Integral Field Unit (IFU) spectroscopy data that the Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) would capture at a redshift of $z\simeq 1.2$. By applying the TW method to these mock observations and comparing the results with the known pattern speeds, we demonstrate that the TW method performs adequately for barred galaxies with bars sufficiently long to be detected by JWST at high redshifts. This work opens a new avenue for applying the TW method to investigate the properties of high-redshift barred galaxies.
