2022年11月,James Webb Space Telescope(JWST)传回了Abell 2744的深度近红外图像;这是一个强大的引力透镜星系团,能够放大其后方遥远而早期的星系。结合现有的Hubble Space Telescope(HST)成像,这一公开数据集开辟了一个全新的发现空间,有助于理解跨越宇宙时间的星系形成与演化中仍存的奥秘。在本工作中,我们在49 arcmin²的JWST覆盖区域内探测并测量了约60,000个天体,在0.32英寸孔径下达到约30星等的5σ极限星等。测光在与最红的NIRCam宽波段F444W的点扩散函数匹配后的图像上使用圆形孔径完成,并清除了明亮的星系团星系及相关星系团内光。为展示测光性能,我们测量了测光红移,并基于已知但规模相对较小的光谱样本获得σ_NMAD≈0.03。随本文,我们公开发布HST和JWST PSF匹配测光星表,其中孔径尺寸经过最优分配以便使用,同时发布单孔径星表、测光红移、静止系颜色和单独的放大率估计。这些星表将为2023年夏季对首批JWST选样本之一开展高效而深入的光谱后续观测奠定基础。
英文摘要:
In November 2022, the James Webb Space Telescope (JWST) returned deep near-infrared images of Abell 2744 -- a powerful lensing cluster capable of magnifying distant, incipient galaxies beyond it. Together with the existing Hubble Space Telescope (HST) imaging, this publicly available dataset opens a fundamentally new discovery space to understand the remaining mysteries of the formation and evolution of galaxies across cosmic time. In this work, we detect and measure some 60,000 objects across the 49 arcmin$^2$ JWST footprint down to a $5\,σ$ limiting magnitude of $\sim$30 mag in 0.32" apertures. Photometry is performed using circular apertures on images matched to the point spread function of the reddest NIRCam broad band, F444W, and cleaned of bright cluster galaxies and the related intra-cluster light. To give an impression of the photometric performance, we measure photometric redshifts and achieve a $σ_{\rm NMAD}\approx0.03$ based on known, but relatively small, spectroscopic samples. With this paper, we publicly release our HST and JWST PSF-matched photometric catalog with optimally assigned aperture sizes for easy use, along with single aperture catalogs, photometric redshifts, rest-frame colors, and individual magnification estimates. These catalogs will set the stage for efficient and deep spectroscopic follow-up of some of the first JWST-selected samples in Summer 2023.
