CANDELS Multi-wavelength Catalogs: Source Identification and Photometry in the CANDELS COSMOS Survey Field
Wuyts, S.; Dickinson, M.; Ferguson, H. C. +36 more
We present a multi-wavelength photometric catalog in the COSMOS field as part of the observations by the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. The catalog is based on Hubble Space Telescope Wide Field Camera 3 (HST/WFC3) and Advanced Camera for Surveys observations of the COSMOS field (centered at R.A.: {10}{{h…
A Herschel Space Observatory Spectral Line Survey of Local Luminous Infrared Galaxies from 194 to 671 Microns
Gao, Yu; Díaz-Santos, Tanio; Lu, Nanyao +18 more
We describe a Herschel Space Observatory 194-671 µm spectroscopic survey of a sample of 121 local luminous infrared galaxies and report the fluxes of the CO J to J-1 rotational transitions for 4≤slant J≤slant 13, the [N II] 205 µm line, the [C I] lines at 609 and 370 µm, as well as additional and usually fainter lines. The CO spe…
Characterizing the Circumgalactic Medium of Nearby Galaxies with HST/COS and HST/STIS Absorption-line Spectroscopy. II. Methods and Models
Savage, Blair D.; Shull, J. Michael; Danforth, Charles W. +6 more
We present basic data and modeling for a survey of the cool, photoionized circumgalactic medium (CGM) of low-redshift galaxies using far-UV QSO absorption-line probes. This survey consists of “targeted” and “serendipitous” CGM subsamples, originally described in Stocke et al. (Paper I). The targeted subsample probes low-luminosity, late-type galax…
The Extended IRTF Spectral Library: Expanded Coverage in Metallicity, Temperature, and Surface Gravity
van Dokkum, Pieter; Conroy, Charlie; Mann, Andrew W. +3 more
We present a 0.7-2.5 µm spectral library of 284 stars observed with the medium-resolution infrared spectrograph, SpeX, at the 3.0 m NASA Infrared Telescope Facility (IRTF) on Maunakea, Hawaii. This library extends the metallicity range of the IRTF Cool Star library beyond solar metallicity to -1.7 < [Fe/H] < 0.6. All of the observed st…
Interstellar Pickup Ion Observations to 38 au
McComas, D. J.; Schwadron, N. A.; Szalay, J. R. +9 more
We provide the first direct observations of interstellar H+ and He+ pickup ions in the solar wind from 22 to 38 au. We use the Vasyliunas and Siscoe model functional form to quantify the pickup ion distributions, and while the fit parameters generally lie outside their physically expected ranges, this form allows fits that qu…
BANYAN. IX. The Initial Mass Function and Planetary-mass Object Space Density of the TW HYA Association
Weinberger, Alycia J.; Donaldson, Jessica K.; Burgasser, Adam J. +15 more
A determination of the initial mass function (IMF) of the current, incomplete census of the 10 Myr-old TW Hya association (TWA) is presented. This census is built from a literature compilation supplemented with new spectra and 17 new radial velocities from ongoing membership surveys, as well as a reanalysis of Hipparcos data that confirmed HR 4334…
A STEREO Survey of Magnetic Cloud Coronal Mass Ejections Observed at Earth in 2008-2012
Howard, Russell A.; Linton, Mark G.; Wood, Brian E. +4 more
We identify coronal mass ejections (CMEs) associated with magnetic clouds (MCs) observed near Earth by the Wind spacecraft from 2008 to mid-2012, a time period when the two STEREO spacecraft were well positioned to study Earth-directed CMEs. We find 31 out of 48 Wind MCs during this period can be clearly connected with a CME that is trackable in S…
The Ages and Masses of a Million Galactic-disk Main-sequence Turnoff and Subgiant Stars from the LAMOST Galactic Spectroscopic Surveys
Shi, Jianrong; Wu, Yaqian; Xiang, Maosheng +10 more
We present estimates of stellar age and mass for 0.93 million Galactic-disk main-sequence turnoff and subgiant stars from the LAMOST Galactic Spectroscopic Surveys. The ages and masses are determined by matching with stellar isochrones using a Bayesian algorithm, utilizing effective temperature {T}{eff}, absolute magnitude {M}V
The Circum-Galactic Medium of Massive Spirals. II. Probing the Nature of Hot Gaseous Halo around the Most Massive Isolated Spiral Galaxies
Bregman, Joel N.; Anderson, Michael E.; Crain, Robert A. +3 more
We present the analysis of the XMM-Newton data of the Circum-Galactic Medium of MASsive Spirals (CGM-MASS) sample of six extremely massive spiral galaxies in the local universe. All the CGM-MASS galaxies have diffuse X-ray emission from hot gas detected above the background extending ∼ (30{--}100) {kpc} from the galactic center. This doubles the e…
Scientific Synergy between LSST and Euclid
Smith, Graham P.; Conselice, Christopher J.; Aubourg, Éric +34 more
Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high-cadence, deep, wide-field optical photometry from LSST with high-resolution, wide-field optical photometry, and near-infrared photometry and spectroscopy from Euclid will be powerful for …
