The Pan-STARRS1 Database and Data Products
Price, P. A.; Rest, A.; Saglia, R. P. +36 more
This paper describes the organization of the database and the catalog data products from the Pan-STARRS1 3π Steradian Survey. The catalog data products are available in the form of an SQL-based relational database from MAST, the Mikulski Archive for Space Telescopes at STScI. The database is described in detail, including the construction of the d…
The Sloan Digital Sky Survey Quasar Catalog: Sixteenth Data Release
Brandt, W. N.; Pâris, Isabelle; Petitjean, Patrick +34 more
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog comprises the largest selection of spectroscopically confirmed quasars to date. The full catalog includes two subcatalogs (the current versions are DR16Q_v4 and DR16Q_Superset_…
Pan-STARRS Photometric and Astrometric Calibration
Price, P. A.; Chambers, K. C.; Stubbs, C. W. +20 more
We present the details of the photometric and astrometric calibration of the Pan-STARRS1 3π Survey. The photometric goals were to reduce the systematic effects introduced by the camera and detectors, and to place all of the observations onto a photometric system with consistent zero-points over the entire area surveyed, the ≈30,000 deg2…
The Zwicky Transient Facility Catalog of Periodic Variable Stars
Tian, Hao; Yang, Ming; Wang, Shu +3 more
The number of known periodic variables has grown rapidly in recent years. Thanks to its large field of view and faint limiting magnitude, the Zwicky Transient Facility (ZTF) offers a unique opportunity to detect variable stars in the northern sky. Here, we exploit ZTF Data Release 2 (DR2) to search for and classify variables down to r ∼ 20.6 mag. …
The SPTpol Extended Cluster Survey
Sharon, K.; Gladders, M. D.; Ade, P. A. R. +135 more
We describe the observations and resultant galaxy cluster catalog from the 2770 deg2 SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich (SZ) effect and confirmed with a combination of archival and targeted follow-up data, making particular use of data from the Dark Energy Survey (DES). With inco…
2SXPS: An Improved and Expanded Swift X-Ray Telescope Point-source Catalog
Cenko, S. B.; Tagliaferri, G.; Kennea, J. A. +8 more
We present the 2SXPS (Swift-XRT Point Source) catalog, containing 206,335 point sources detected by the Swift X-ray Telescope (XRT) in the 0.3-10 keV energy range. This catalog represents a significant improvement over 1SXPS, with double the sky coverage (now 3790 deg2), and several significant developments in source detection and class…
The ALPINE-ALMA [C II] Survey: Multiwavelength Ancillary Data and Basic Physical Measurements
Cimatti, A.; Pozzi, F.; Rodighiero, G. +37 more
We present the ancillary data and basic physical measurements for the galaxies in the ALMA Large Program to Investigate C+ at Early Times (ALPINE) survey - the first large multiwavelength survey that aims at characterizing the gas and dust properties of 118 main-sequence galaxies at redshifts 4.4 < z < 5.9 via the measurement of […
CME-CME Interactions as Sources of CME Geoeffectiveness: The Formation of the Complex Ejecta and Intense Geomagnetic Storm in 2017 Early September
Veronig, Astrid M.; Dumbović, Mateja; Temmer, Manuela +9 more
Coronal mass ejections (CMEs) are the primary sources of intense disturbances at Earth, where their geoeffectiveness is largely determined by their dynamic pressure and internal magnetic field, which can be significantly altered during interactions with other CMEs in interplanetary space. We analyze three successive CMEs that erupted from the Sun …
Synthetic Gaia Surveys from the FIRE Cosmological Simulations of Milky Way-mass Galaxies
Faucher-Giguère, Claude-André; Sharma, Sanjib; Hopkins, Philip F. +6 more
With Gaia Data Release 2, the astronomical community is entering a new era of multidimensional surveys of the Milky Way. This new phase-space view of our Galaxy demands new tools for comparing observations to simulations of Milky Way-mass galaxies in a cosmological context, to test the physics of both dark matter and galaxy formation. We present a…
The Multi-INstrument Burst ARchive (MINBAR)
Watts, Anna L.; Galloway, Duncan K.; Kuulkers, Erik +7 more
We present the largest sample of type I (thermonuclear) X-ray bursts yet assembled, comprising 7083 bursts from 85 bursting sources. The sample is drawn from observations with Xenon-filled proportional counters on the long-duration satellites RXTE, BeppoSAX, and International Gamma-Ray Astrophysics Laboratory between 1996 February 8 and 2012 May 3…
