Star Formation Conditions in a Planck Galactic Cold Clump, G108.84-00.81
Kim, Kee-Tae; Lee, Jeong-Eun; Liu, Tie +6 more
We present the results from a series of ground-based radio observations toward a Planck Galactic Cold Clump (PGCC), PGCC G108.84-00.81, which is located in one curved filamentary cloud in the vicinity of an extended H II region Sh2-152 and SNR G109.1-1.0. PGCC G108.84-00.81 is mainly composed of two clumps, “G108-N” and “G108-S”. In the 850 µ…
Exploring the SDSS Data Set with Linked Scatter Plots. I. EMP, CEMP, and CV Stars
Carbon, Duane F.; Henze, Christopher; Nelson, Bron C.
We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on linked scatter plots (LSPs). Our approach is especially designed to work with very large spectrum data sets such as the SDSS, LAMOST, RAVE, and Gaia data sets, and it can be…
An Improved Method for Determining the Integrated Properties of Nuclear Rings: NGC 1512
Ho, Luis C.; de Grijs, Richard; Ma, Chao
The integrated properties of nuclear rings are correlated with the secular evolution and dynamics of the host galaxies of the rings, as well as with the formation and evolution of the rings’ star cluster population(s). Here we present a new method to accurately measure the spectral energy distribution and current star formation rate (SFR) of the n…
The InterPlanetary Network Supplement to the Second Fermi GBM Catalog of Cosmic Gamma-Ray Bursts
Zhang, X.; Cline, T.; Hurley, K. +32 more
InterPlanetary Network (IPN) data are presented for the gamma-ray bursts in the second Fermi Gamma-Ray Burst Monitor (GBM) catalog. Of the 462 bursts in that catalog between 2010 July 12 and 2012 July 11, 428, or 93%, were observed by at least 1 other instrument in the 9-spacecraft IPN. Of the 428, the localizations of 165 could be improved by tri…
Measuring Filament Orientation: A New Quantitative, Local Approach
Green, C. -E.; Dawson, J. R.; Cunningham, M. R. +3 more
The relative orientation between filamentary structures in molecular clouds and the ambient magnetic field provides insight into filament formation and stability. To calculate the relative orientation, a measurement of filament orientation is first required. We propose a new method to calculate the orientation of the one-pixel-wide filament skelet…

The COSMOS2015 Catalog: Exploring the 1 < z < 6 Universe with Half a Million Galaxies
Aussel, H.; Le Floc'h, E.; Sanders, D. B. +34 more
We present the COSMOS201524 catalog, which contains precise photometric redshifts and stellar masses for more than half a million objects over the 2deg2 COSMOS field. Including new {{YJHK}}{{s}} images from the UltraVISTA-DR2 survey, Y-band images from Subaru/Hyper-Suprime-Cam, and infrared data from the Spitzer La…
The 3D-HST Survey: Hubble Space Telescope WFC3/G141 Grism Spectra, Redshifts, and Emission Line Measurements for ~ 100,000 Galaxies
Maseda, Michael V.; van Dokkum, Pieter G.; Franx, Marijn +27 more
We present reduced data and data products from the 3D-HST survey, a 248-orbit HST Treasury program. The survey obtained WFC3 G141 grism spectroscopy in four of the five CANDELS fields: AEGIS, COSMOS, GOODS-S, and UDS, along with WFC3 H 140 imaging, parallel ACS G800L spectroscopy, and parallel I 814 imaging. In a previous pap…
Development of the Model of Galactic Interstellar Emission for Standard Point-source Analysis of Fermi Large Area Telescope Data
Troja, E.; Caraveo, P. A.; Mirabal, N. +131 more
Most of the celestial γ rays detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope originate from the interstellar medium when energetic cosmic rays interact with interstellar nucleons and photons. Conventional point-source and extended-source studies rely on the modeling of this diffuse emission for accurate char…
Spectral Properties of Cool Stars: Extended Abundance Analysis of 1,617 Planet-search Stars
Valenti, Jeff A.; Fischer, Debra A.; Brewer, John M. +1 more
We present a catalog of uniformly determined stellar properties and abundances for 1,617 F, G, and K stars using an automated spectral synthesis modeling procedure. All stars were observed using the HIRES spectrograph at Keck Observatory. Our procedure used a single line list to fit model spectra to observations of all stars to determine effective…
