The Panchromatic Hubble Andromeda Treasury (PHAT) survey is an on-going Hubble Space Telescope (HST) multi-cycle program to obtain high spatial resolution imaging of one-third of the M31 disk at ultraviolet through near-infrared wavelengths. In this paper, we present the first installment of the PHAT stellar cluster catalog. When completed, the PHAT cluster catalog will be among the largest and most comprehensive surveys of resolved star clusters in any galaxy. The exquisite spatial resolution achieved with HST has allowed us to identify hundreds of new clusters that were previously inaccessible with existing ground-based surveys. We identify 601 clusters in the Year 1 sample, representing more than a factor of four increase over previous catalogs within the current survey area (390 arcmin^2). This work presents results derived from the first \sim25% of the survey data; we estimate that the final sample will include \sim2500 clusters. For the Year 1 objects, we present a catalog with positions, radii, and six-band integrated photometry. Along with a general characterization of the cluster luminosities and colors, we discuss the cluster luminosity function, the cluster size distributions, and highlight a number of individually interesting clusters found in the Year 1 search.
A Precision Multi-Band Two-Epoch Photometric Catalog of 44 Million Sources in the Northern Sky from Combination of the USNO-B and Sloan Digital Sky Survey Catalogs
下一代宽视场光学和无线电测量的一个关键科学驱动力是对时变天空的探索。这些调查将具有前所未有的敏感性和覆盖面,但在比调查寿命更长的时间尺度上发现变化的能力将受到限制。我们提出了一个新的精度,多历元的光度计目录,跨越60年,结合USNO-B和SDSS数据发布9目录。我们重新校准了原始USNO-B星表的测光,并创建了一个星表,其中包含位于北天DR 9足迹中的43,647,887个光学点源的两个测光时期,最多可达5个不同波段。重新校准的对象跨越的幅度范围14 < m < 20,是准确的$\approx$ 0.1马格。我们最大限度地减少虚假的对象和那些不准确的幅度通过识别和删除几个来源的系统误差在两个起源目录,重点虚假的对象,表现出大的视星等变化。在考虑了这些影响之后,我们发现$\approx$ 250,000颗恒星和类星体在USNO-B和SDSS DR 9时期之间显示出显著的(> 4 $σ$)亮度变化。讨论了该星表的历史价值及其在长时标、大振幅变星和类星体研究中的应用。

The Deep Extragalactic VIsible Legacy Survey (DEVILS) is an ongoing high-completeness, deep spectroscopic survey of $\sim$60,000 galaxies to Y$<$21.2 mag, over $\sim$6 deg2 in three well-studied deep extragalactic fields: D10 (COSMOS), D02 (XMM-LSS) and D03 (ECDFS). Numerous DEVILS projects all require consistent, uniformly-derived and state-of-the-art photometric data with which to measure galaxy properties. Existing photometric catalogues in these regions either use varied photometric measurement techniques for different facilities/wavelengths leading to inconsistencies, older imaging data a…
