The Galactic Plane Infrared Polarization Survey (GPIPS): Data Release 4
Jameson, K. E.; Cerny, C.; Montgomery, J. +7 more
The Galactic Plane Infrared Polarization Survey (GPIPS) seeks to characterize the magnetic field in the dusty Galactic disk using near-infrared stellar polarimetry. All GPIPS observations were completed using the 1.83 m Perkins telescope and Mimir instrument. GPIPS observations surveyed 76 deg2 of the northern Galactic plane, from Galac…
The Spectroscopic Follow-up of the QUBRICS Bright Quasar Survey
Grazian, Andrea; Boutsia, Konstantina; Amorin, Ricardo +11 more
We present the results of the spectroscopic follow-up of the QUasars as BRIght beacons for Cosmology in the Southern Hemisphere (QUBRICS; Calderone et al. 2019) survey. The selection method is based on a machine-learning approach applied to photometric catalogs, covering an area of ∼12,400 deg2 in the Southern Hemisphere. The spectrosco…
Detailed Imaging of Coronal Rays with the Parker Solar Probe
Vourlidas, Angelos; Poirier, Nicolas; Kouloumvakos, Athanasios +13 more
The Wide-field Imager for Solar PRobe (WISPR) obtained the first high-resolution images of coronal rays at heights below 15 R⊙ when the Parker Solar Probe (PSP) was located inside 0.25 au during the first encounter. We exploit these remarkable images to reveal the structure of coronal rays at scales that are not easily discernible in im…
LAMOST Observations in 15 K2 Campaigns. I. Low-resolution Spectra from LAMOST DR6
Shi, Jianrong; Zong, Weikai; Fu, Jian-Ning +12 more
The Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST)-K2 (LK2) project, initiated in 2015, aims to collect low-resolution spectra of targets in the K2 campaigns, similar to the LAMOST-Kepler project. By the end of 2018, a total of 126 LK2 plates had been observed by LAMOST. After cross-matching the catalog of the LAMOST data relea…
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…
