PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-forming Galaxies
DOI: 10.3847/1538-4365/ac17f3 Bibcode: 2021ApJS..257...43L

Sandstrom, Karin M.; Bolatto, Alberto D.; Henshaw, Jonathan D. +69 more

We present PHANGS-ALMA, the first survey to map CO J = 2 → 1 line emission at ~1″ ~100 pc spatial resolution from a representative sample of 90 nearby (d ≲ 20 Mpc) galaxies that lie on or near the z = 0 "main sequence" of star-forming galaxies. CO line emission traces the bulk distribution of molecular gas, which is the cold, star-forming phase of…

The TESS Objects of Interest Catalog from the TESS Prime Mission
DOI: 10.3847/1538-4365/abefe1 Bibcode: 2021ApJS..254...39G

Jayaraman, Rahul; Pál, András; Torres, Guillermo +102 more

We present 2241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its 2 yr Prime Mission. We list these candidates in the TESS Objects of Interest (TOI) Catalog, which includes both new planet candidates found by TESS and previously known planets recovered by TESS observations. We describe the p…

The Dark Energy Survey Data Release 2
DOI: 10.3847/1538-4365/ac00b3 Bibcode: 2021ApJS..255...20A

Bacon, D.; Bechtol, K.; Juneau, S. +135 more

We present the second public data release of the Dark Energy Survey, DES DR2, based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4 m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DES DR2 consists of reduced single-epoch and coadded images, a source catalog derived from coadded images, and associ…

The Hipparcos-Gaia Catalog of Accelerations: Gaia EDR3 Edition
DOI: 10.3847/1538-4365/abf93c Bibcode: 2021ApJS..254...42B

Brandt, Timothy D.

We present a cross-calibration of Hipparcos and Gaia EDR3 intended to identify astrometrically accelerating stars and to fit orbits to stars with faint, massive companions. The resulting catalog, the EDR3 edition of the Hipparcos-Gaia Catalog of Accelerations (HGCA), provides three proper motions with calibrated uncertainties on the EDR3 reference…

The California Legacy Survey. I. A Catalog of 178 Planets from Precision Radial Velocity Monitoring of 719 Nearby Stars over Three Decades
DOI: 10.3847/1538-4365/abe23c Bibcode: 2021ApJS..255....8R

Henry, Gregory W.; Knutson, Heather A.; Kane, Stephen R. +20 more

We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164 known exoplanets and 14 newly discovered or revised exoplanets and substellar companions. This catalog updated the orbital parameters of known exoplanets and long-period candidates, some of which have decades-longer observational baselines than they did upon …

Teplitz, Harry I.; Schlegel, David J.; Mobasher, Bahram +20 more

The CatWISE2020 Catalog consists of 1,890,715,640 sources over the entire sky selected from Wide-field Infrared Survey Explorer (WISE) and NEOWISE survey data at 3.4 and 4.6 µm (W1 and W2) collected from 2010 January 7 to 2018 December 13. This data set adds two years to that used for the CatWISE Preliminary Catalog, bringing the total to si…

Molecules with ALMA at Planet-forming Scales (MAPS). I. Program Overview and Highlights
DOI: 10.3847/1538-4365/ac1432 Bibcode: 2021ApJS..257....1O

Zhang, Ke; Wilner, David J.; Ménard, François +35 more

Planets form and obtain their compositions in dust- and gas-rich disks around young stars, and the outcome of this process is intimately linked to the disk chemical properties. The distributions of molecules across disks regulate the elemental compositions of planets, including C/N/O/S ratios and metallicity (O/H and C/H), as well as access to wat…

California Legacy Survey. II. Occurrence of Giant Planets beyond the Ice Line
DOI: 10.3847/1538-4365/abfcc1 Bibcode: 2021ApJS..255...14F

Henry, Gregory W.; Knutson, Heather A.; Kane, Stephen R. +20 more

We used high-precision radial velocity measurements of FGKM stars to determine the occurrence of giant planets as a function of orbital separation spanning 0.03-30 au. Giant planets are more prevalent at orbital distances of 1-10 au compared to orbits interior or exterior of this range. The increase in planet occurrence at ~1 au by a factor of ~4 …

Benoit-Lévy, A.; Bechtol, K.; Smith, M. +112 more

We describe the Dark Energy Survey (DES) photometric data set assembled from the first three years of science operations to support DES Year 3 cosmologic analyses, and provide usage notes aimed at the broad astrophysics community. Y3 GOLD improves on previous releases from DES, Y1 GOLD, and Data Release 1 (DES DR1), presenting an expanded and cura…

A Quick Look at the 3 GHz Radio Sky. I. Source Statistics from the Very Large Array Sky Survey

Safi-Harb, Samar; Baum, Stefi A.; O'Dea, Christopher P. +8 more

The Very Large Array Sky Survey (VLASS) is observing the entire sky north of -40° in the S band (2 GHz < ν < 4 GHz), with the highest angular resolution (2"5) of any all-sky radio continuum survey to date. VLASS will cover its entire footprint over three distinct epochs, the first of which has now been observed in full. Based on Quick Look i…
