CMZoom. II. Catalog of Compact Submillimeter Dust Continuum Sources in the Milky Way's Central Molecular Zone
Ho, Luis C.; Ott, Jürgen; Lu, Xing +19 more
In this paper we present the CMZoom survey's catalog of compact sources (<10″, ∼0.4 pc) within the central molecular zone (CMZ). CMZoom is a Submillimeter Array large program designed to provide a complete and unbiased map of all high column density gas (N(H2) ≥ 1023 cm-2) of the innermost 500 pc of the Galaxy i…
GalWeight Application: A Publicly Available Catalog of Dynamical Parameters of 1800 Galaxy Clusters from SDSS-DR13, (GalWCat19)
Old, Lyndsay; Wilson, Gillian; Abdullah, Mohamed H. +3 more
Utilizing the SDSS-DR13 spectroscopic data set, we create a new publicly available catalog of 1800 galaxy clusters (GalWeight cluster catalog, GalWCat19) and a corresponding catalog of 34,471 identified member galaxies. The clusters are identified from overdensities in redshift phase space. The GalWeight technique introduced by Abdullah et al. is …
A Catalog of RV Variable Star Candidates from LAMOST
Liu, Gaochao; Wu, Yaqian; Xiang, Maosheng +14 more
Radial velocity (RV) variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ∼6.5 million stellar spectra in its Data Release 4 (DR4). During the survey ∼4.7 million unique sources were targeted and ∼1 million stars observed repeatedly. The probabilities…
Morphological Reconstruction of a Small Transient Observed by Parker Solar Probe on 2018 November 5
Stenborg, Guillermo; Howard, Russell A.; Hess, Phillip +2 more
On 2018 November 5, about 24 hr before the first close perihelion passage of Parker Solar Probe (PSP), a coronal mass ejection (CME) entered the field of view of the inner detector of the Wide-field Imager for Solar PRobe (WISPR) instrument on board PSP, with the northward component of its trajectory carrying the leading edge of the CME off the to…
Dippers from the TESS Full-frame Images. I. Results of the First One Year Data and Discovery of a Runaway Dipper
Takita, Satoshi; Hattori, Kohei; Muto, Takayuki +9 more
We present a comprehensive catalog of the dippers—young stellar objects that exhibit episodic dimming—derived from one year's worth of data of the Transiting Exoplanet Survey Satellite (TESS) full-frame images. In the survey, we found 35 dippers using the convolutional neural network, most of them newly discovered. Although these dippers are widel…
Experimental Phase Function and Degree of Linear Polarization Curves of Millimeter-sized Cosmic Dust Analogs
Sierks, H.; Blum, J.; Fulle, M. +22 more
We present laboratory measurements of the phase functions and degree of linear polarization (DLP) curves of a selection of millimeter-sized cosmic dust analog particles. The set includes particles with similar sizes but diverse internal structure (compact and porous) and absorbing properties. The measured phase functions are found to be in all cas…
Deciphering the Large-scale Environment of Radio Galaxies in the Local Universe. II. A Statistical Analysis of Environmental Properties
Capetti, A.; Tramacere, A.; Campana, R. +6 more
In our previous analysis we investigated the large-scale environment of two samples of radio galaxies (RGs) in the local universe (I.e., with redshifts zsrc ≤ 0.15), classified as FR I and FR II on the basis of their radio morphology. The analysis was carried out using (I) extremely homogeneous catalogs and (II) a new method, known as c…
In the Trenches of the Solar-Stellar Connection. I. Ultraviolet and X-Ray Flux-Flux Correlations across the Activity Cycles of the Sun and Alpha Centauri AB
Ayres, Thomas R.
This study focuses on high-energy proxies of stellar magnetic activity over long-term starspot cycles of three low-activity Sun-like stars: α Centauri A (HD 128620: G2 V), α Cen B (HD 128621: K1 V), and the Sun itself. Data sets include: daily solar ultraviolet irradiance spectra and X-ray fluxes from the Solar Radiation and Climate Experiment, du…
HST/COS Observations of Quasar Outflows in the 500-1050 Å Rest Frame. II. The Most Energetic Quasar Outflow Measured to Date
Xu, Xinfeng; Kriss, Gerard A.; Arav, Nahum +2 more
We present a study of the BAL outflows seen in quasar SDSS J1042+1646 (z = 0.978) in the rest-frame 500-1050 Å (EUV500) region. The results are based on the analysis of recent Hubble Space Telescope/Cosmic Origins Spectrograph observations. Five outflow systems are identified, where, in total, they include ∼70 outflow troughs from ionic transition…
Matched Photometric Catalogs of GALEX UV Sources with Gaia DR2 and SDSS DR14 Databases (GUVmatch)
Bianchi, Luciana; Shiao, Bernard
We have matched the ultraviolet (UV) sources in GUVcat_AIS with optical databases that have similar depth and wide sky coverage. GUVcat_AIS has Galaxy Evolution Explorer (GALEX) far-UV (FUV, λeff ∼ 1528 Å) and near-UV (NUV, λeff ∼ 2310 Å) photometry of ≈83 million sources, covering 24,788 square degrees of the sky, with a typ…
