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…
The CatWISE Preliminary Catalog: Motions from WISE and NEOWISE Data
Teplitz, Harry I.; Schlegel, David J.; Mobasher, Bahram +19 more
CatWISE is a program to catalog sources selected from combined WISE and NEOWISE all-sky survey data at 3.4 and 4.6 &mgrm (W1 and W2). The CatWISE Preliminary Catalog consists of 900,849,014 sources measured in data collected from 2010 to 2016. This data set represents four times as many exposures and spans over 10 times as large a time baselin…
Scaling K2. I. Revised Parameters for 222,088 K2 Stars and a K2 Planet Radius Valley at 1.9 R⊕
Schlieder, Joshua E.; Ciardi, David R.; Dressing, Courtney D. +3 more
Previous measurements of stellar properties for K2 stars in the Ecliptic Plane Input Catalog largely relied on photometry and proper motion measurements, with some added information from available spectra and parallaxes. Combining Gaia DR2 distances with spectroscopic measurements of effective temperatures, surface gravities, and metallicities fro…
The R-Process Alliance: Fourth Data Release from the Search for R-process-enhanced Stars in the Galactic Halo
Grebel, Eva K.; Drout, Maria R.; Steinmetz, Matthias +22 more
This compilation is the fourth data release from the R-Process Alliance (RPA) search for r-process-enhanced stars and the second release based on "snapshot" high-resolution (R ∼ 30,000) spectra collected with the du Pont 2.5 m Telescope. In this data release, we propose a new delineation between the r-I and r-II stellar classes at $[\mathrm{Eu}/\m…
Structure of Brightest Cluster Galaxies and Intracluster Light
Brosch, N.; Schmidt, M.; Bender, R. +6 more
Observations of 170 local (z ≲ 0.08) galaxy clusters in the northern hemisphere have been obtained with the Wendelstein Telescope Wide Field Imager (WWFI). We correct for systematic effects such as point-spread function broadening, foreground star contamination, relative bias offsets, and charge persistence. Background inhomogeneities induced by s…
The Separation Distribution of Ultrawide Binaries across Galactic Populations
Tian, Hai-Jun; Rix, Hans-Walter; Gould, Andrew +1 more
We present an extensive and pure sample of ultrawide binary stars with separations of 0.01 ≲ s/pc ≲ 1 in the solar neighborhood. Using data from Gaia DR2, we define kinematic subpopulations via the systems’ tangential velocities, I.e., disk-like (V ⊥,tot ≤ 40 km s-1), intermediate (V ⊥,tot = 40-85 km s-1…
Morpheus: A Deep Learning Framework for the Pixel-level Analysis of Astronomical Image Data
Hausen, Ryan; Robertson, Brant E.
We present Morpheus, a new model for generating pixel-level morphological classifications of astronomical sources. Morpheus leverages advances in deep learning to perform source detection, source segmentation, and morphological classification pixel-by-pixel via a semantic segmentation algorithm adopted from the field of computer vision. By utilizi…
