Search for quasar pairs with Gaia astrometric data
Quasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction and clustering, the coevolution between the two quasars’ host galaxies, and the growth of supermassive black holes, as well as the formation and ...

CANDELS Multi-wavelength Catalogs: Source Identification and Photometry in the CANDELS Extended Groth Strip [PDF]
We present a 0.4–8 μm multi-wavelength photometric catalog in the Extended Groth Strip (EGS) field. This catalog is built on the Hubble Space Telescope (HST) WFC3 and ACS data from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey ...

Mining gravitational-wave catalogs to understand binary stellar evolution: A new hierarchical Bayesian framework [PDF]
Catalogs of stellar-mass compact binary systems detected by ground-based gravitational-wave instruments (such as LIGO and Virgo) will offer insights into the demographics of progenitor systems and the physics guiding stellar evolution.

20cm VLA radio-continuum study of M31: Images and point source catalogues [PDF]
We present a series of new high-sensitivity and high-resolution radio-continuum images of M31 at λ=20 cm (ν=1.4 GHz). These new images were produced by merging archived 20 cm radio-continuum observations from the Very Large Array (VLA) telescope.

HFF-DeepSpace Photometric Catalogs of the 12 Hubble Frontier Fields, Clusters, and Parallels: Photometry, Photometric Redshifts, and Stellar Masses [PDF]
We present Hubble multi-wavelength photometric catalogs, including (up to) 17 filters with the Advanced Camera for Surveys and Wide Field Camera 3 from the ultra-violet to near-infrared for the Hubble Frontier Fields and associated parallels.

catsHTM: A Tool for Fast Accessing and Cross-matching Large Astronomical Catalogs [PDF]
Fast access to large catalogs is required for some astronomical applications. Here we introduce the catsHTM tool, consisting of several large catalogs reformatted into HDF5-based file format, which can be downloaded and used locally. To allow fast access,

Chandra Observations of the X-Ray Binary Population in the Field of the Dwarf Galaxy IC 10
IC 10 is a dwarf galaxy in Cassiopeia, located at a distance of 660 kpc, and hosts a young stellar population, a large number of Wolf–Rayet stars, and a large number of massive stars in general.

Spitzer Matching Survey of the UltraVISTA Ultra-deep Stripes (SMUVS): Full-mission IRAC Mosaics and Catalogs [PDF]
This paper describes new deep 3.6 and 4.5 μm imaging of three UltraVISTA near-infrared survey stripes within the COSMOS field. The observations were carried out with Spitzer’s Infrared Array Camera (IRAC) for the Spitzer Matching Survey of the UltraVISTA
