ALMA Lensing Cluster Survey: Hubble Space Telescope and Spitzer Photometry of 33 Lensed Fields Built with CHArGE
Magdis, G. E.; Wang, T.; Bauer, F. E. +30 more
We present a set of multiwavelength mosaics and photometric catalogs in the Atacama Large Millimeter/submillimeter Array (ALMA) lensing cluster survey fields. The catalogs were built by the reprocessing of archival data from the Complete Hubble Archive for Galaxy Evolution compilation, taken by the Hubble Space Telescope (HST) in the Reionization …
CMB/kSZ and Compton-y Maps from 2500 deg2 of SPT-SZ and Planck Survey Data
Bleem, L. E.; Stark, A. A.; George, E. M. +37 more
We present component-separated maps of the primary cosmic microwave background/kinematic Sunyaev-Zel'dovich (SZ) amplitude and the thermal SZ Compton-y parameter, created using data from the South Pole Telescope (SPT) and the Planck satellite. These maps, which cover the ~2500 deg2 of the southern sky imaged by the SPT-SZ survey, repres…
The GALPROP Cosmic-ray Propagation and Nonthermal Emissions Framework: Release v57
Jóhannesson, G.; Moskalenko, I. V.; Porter, T. A.
The past decade has brought impressive advances in the astrophysics of cosmic rays (CRs) and multiwavelength astronomy, thanks to the new instrumentation launched into space and built on the ground. Modern technologies employed by those instruments provide measurements with unmatched precision, enabling searches for subtle signatures of dark matte…
The DECam Local Volume Exploration Survey Data Release 2
Bacon, D.; Bechtol, K.; Smith, M. +125 more
We present the second public data release (DR2) from the DECam Local Volume Exploration survey (DELVE). DELVE DR2 combines new DECam observations with archival DECam data from the Dark Energy Survey, the DECam Legacy Survey, and other DECam community programs. DELVE DR2 consists of ~160,000 exposures that cover >21,000 deg2 of the hi…
The California Legacy Survey. III. On the Shoulders of (Some) Giants: The Relationship between Inner Small Planets and Outer Massive Planets
Henry, Gregory W.; Knutson, Heather A.; Kane, Stephen R. +11 more
We use a high-precision radial velocity survey of FGKM stars to study the conditional occurrence of two classes of planets: close-in small planets (0.023-1 au, 2-30 M ⊕) and distant giant planets (0.23-10 au, 30-6000 M ⊕). We find that ${41}_{-13}^{+15} \% $ of systems with a close-in, small planet also host an outer giant, c…
A Search of the Full Six Years of the Dark Energy Survey for Outer Solar System Objects
Smith, M.; Allam, S.; Bertin, E. +64 more
We present a search for outer solar system objects in the 6 yr of data from the Dark Energy Survey (DES). The DES covered a contiguous 5000 deg2 of the southern sky with ≈80,000 3 deg2 exposures in the grizY filters between 2013 and 2019. This search yielded 812 trans-Neptunian objects (TNOs), one Centaur and one Oort cloud c…
The R-process Alliance: A Nearly Complete R-process Abundance Template Derived from Ultraviolet Spectroscopy of the R-process-enhanced Metal-poor Star HD 222925
Beers, Timothy C.; Placco, Vinicius M.; Hattori, Kohei +9 more
We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H] = -1.46 ± 0.10) r-process-enhanced ([Eu/Fe] = +1.32 ± 0.08) halo star HD 222925. This abundance set is the most complete for any object beyond the solar system, with a total of 63 metals detected and seven with upper limits. It compr…
Chemical Cartography with APOGEE: Mapping Disk Populations with a 2-process Model and Residual Abundances
Bizyaev, Dmitry; Pan, Kaike; Schneider, Donald P. +33 more
We apply a novel statistical analysis to measurements of 16 elemental abundances in 34,410 Milky Way disk stars from the final data release (DR17) of APOGEE-2. Building on recent work, we fit median abundance ratio trends [X/Mg] versus [Mg/H] with a 2-process model, which decomposes abundance patterns into a "prompt" component tracing core-collaps…
BASS. XXI. The Data Release 2 Overview
Lamperti, Isabella; Cenko, S. Bradley; Schawinski, Kevin +24 more
The BAT AGN Spectroscopic Survey (BASS) is designed to provide a highly complete census of the key physical parameters of the supermassive black holes (SMBHs) that power local active galactic nuclei (AGNs) (z ≲ 0.3), including their bolometric luminosity (L bol), black hole (BH) mass (M BH), accretion rates (L bol/…
A Blind All-sky Search for Star Clusters in Gaia EDR3: 886 Clusters within 1.2 kpc of the Sun
Luo, Yangping; Wang, Kun; Liu, Xiaochen +3 more
Although previous searches for star clusters have been very successful, many clusters are likely still omitted, especially at high-Galactic-latitude regions. In this work, based on the astrometry of Gaia EDR3, we searched nearby (ϖ > 0.8 mas) all-sky regions, obtaining 886 star clusters, of which 270 candidates have not been cataloged before. A…
