VLA FF survey: star-forming galaxy radii
To investigate the growth history of galaxies, we measure the rest-frame radio, ultraviolet (UV), and optical sizes of 98 radio-selected, star-forming galaxies (SFGs)... -
SDSS J1723+3411 UV and optical spectra at z=1.3293
For the extremely bright lensed galaxy SDSSJ1723+3411 at z=1.3293, we analyze spatially integrated MMT, Keck, and Hubble Space Telescope spectra that fully cover the rest-frame... -
HAZMAT VII. Early M-dwarfs FUV em. line, Age and Prot
The ultraviolet (UV) emission from the most numerous stars in the universe, M dwarfs, impacts the formation, chemistry, atmospheric stability, and surface habitability of their... -
X-Ray binary population in M31
We present our analysis of high-quality high-mass X-ray binary (HMXB) candidates in M31 selected from point-source optical counterpart candidates from the Chandra-PHAT survey... -
Evolution of C^IV^ absorbers. I. Absorber properties
We present a large high-resolution study of the distribution and evolution of C^IV^ absorbers, including the weakest population with equivalent widths W_r_<0.3{AA} . By... -
SDSS Hbeta & C^IV^ reverberation mapped AGNs
It is well known that reverberation mapping of active galactic nuclei (AGNs) reveals a relationship between AGN luminosity and the size of the broad-line region, and that use of... -
Six warm metal-poor stars iron abundances
Neutral Fe lines in metal-poor stars yield conflicting abundances depending on whether and how deviations from local thermodynamic equilibrium (LTE) are considered. We have... -
Abundances in 6 metal-poor stars
We present new abundances derived from CuI, CuII, ZnI, and ZnII lines in six warm (5766<=T_eff_<=6427K), metal-poor (-2.50<=[Fe/H]<=-0.95) dwarf and subgiant... -
Clumpy galaxies in CANDELS. II. 0.5<=z<3.0
Studying giant star-forming clumps in distant galaxies is important to understand galaxy formation and evolution. At present, however, observers and theorists have not reached a... -
Stripe 82X survey multiwavelength catalog
Multiwavelength surveys covering large sky volumes are necessary to obtain an accurate census of rare objects such as high-luminosity and/or high-redshift active galactic nuclei... -
HST UV-IR photometry in CLASH galaxy clusters
We present a new method for photometering objects in galaxy clusters. We introduce a mode-filtering technique for removing spatially variable backgrounds, improving both... -
~1.5yr Swift observations of Mrk 421
We present the results of the Swift observations of the nearby BL Lac object Mrk421 during 2013 November-2015 June. The source exhibited a strong long-term variability in the... -
HeII photoionization rates of quasars
The HeII transverse proximity effect-enhanced HeII Ly{alpha} transmission in a background sightline caused by the ionizing radiation of a foreground quasar-offers a unique... -
Rapidly pulsating sdB stars search with GALEX
NASA's Galaxy Evolution Explorer (GALEX) provided near- and far-UV observations for approximately 77% of the sky over a 10-year period; however, the data reduction pipeline... -
A^3^{Pi}-X^3^{Sigma}^-^ transitions of OH+
The OH^+^ ion is of critical importance to the chemistry in the interstellar medium and is a prerequisite for the generation of more complex chemical species. Submillimeter and... -
HST/COS observations of 7 white dwarfs
The search for transiting habitable exoplanets has broadened to include several types of stars that are smaller than the Sun in an attempt to increase the observed transit depth... -
Abundances of metal-poor star HD 94028
We present a detailed analysis of the composition and nucleosynthetic origins of the heavy elements in the metal-poor ([Fe/H]=-1.62+/-0.09) star HD 94028. Previous studies... -
SDSS-DR7 QSOs with X-ray and UV luminosities
The observed relation between the soft X-ray and the optical-ultraviolet emission in active galactic nuclei (AGNs) is nonlinear and it is usually parametrized as a dependence... -
HST observations of QSOs with medium spectra
We use the Hubble Space Telescope (HST) archive of ultraviolet (UV) quasar spectroscopy to conduct the first blind survey for damped Ly{alpha} absorbers (DLAs) at low redshift... -
SFR-M_*_ relation from ZFOURGE
We explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M_). Using data from the FourStar Galaxy...
