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... -
HST/COS survey of z<0.9 AGNs. I.
We use high-quality, medium-resolution Hubble Space Telescope/Cosmic Origins Spectrograph (HST/COS) observations of 82 UV-bright active galactic nuclei (AGNs) at redshifts... -
z<0.16 CIV absorbers from HST/COS QSOs spectra
To investigate the evolution of metal-enriched gas over recent cosmic epochs as well as to characterize the diffuse, ionized, metal-enriched circumgalactic medium, we have... -
UV continuum for z~4-7 star-forming galaxies
Ultra-deep Advanced Camera for Surveys (ACS) and WFC3/IR HUDF+HUDF09 data, along with the wide-area GOODS+ERS+CANDELS data over the CDF-S GOODS field, are used to measure UV... -
UV spectroscopy of solar-mass stars
We compare high-resolution ultraviolet spectra of the Sun and thirteen solar-mass main-sequence stars with different rotational periods that serve as proxies for their different... -
LAE galaxies in the ECDF-S at z~2.1 and z~3.1
We present a rest-frame ultraviolet morphological analysis of 108 z~2.1 Ly{alpha} emitters (LAEs) in the Extended Chandra Deep Field South and compare it to a similar sample of... -
CI radial velocities with HST/STIS
We analyzed absorption features arising from interstellar neutral carbon that appeared in the UV spectra of 89 stars recorded in the highest resolution echelle modes of the... -
UV star-forming association in spiral galaxies
We investigate recent star formation in the extended ultraviolet (XUV) disks of five nearby galaxies (NGC 0628, NGC 2090, NGC 2841, NGC 3621, and NGC 5055) using a long... -
The abundance of boron in diffuse clouds
We present a comprehensive survey of boron abundances in diffuse interstellar clouds from observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble... -
A panchromatic study of BLAST counterparts
We carry out a multi-wavelength study of individual galaxies detected by the Balloon-borne Large Aperture Submillimeter Telescope (BLAST) and identified at other wavelengths,... -
FUV diffuse emission from the LMC
We present the first observations of diffuse radiation in the far-ultraviolet (FUV; 1000-1150{AA}) from the Large Magellanic Cloud based on observations made with the Far... -
z~6 galaxies UV luminosity function
We have detected 506 i-dropouts (z~6 galaxies) in deep, wide-area HST ACS fields: HUDF, enhanced GOODS, and HUDF parallel ACS fields (HUDF-Ps). The contamination levels are... -
UV through far-IR analysis of M81
The recent star formation (SF) in the early-type spiral galaxy M81 is characterized using imaging observations from the far-ultraviolet to the far-infrared. We compare these... -
NGC4395 light curves
A reverberation-mapping program on NGC 4395, the least luminous known Seyfert 1 galaxy, undertaken with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope... -
Star formation in Stephan's Quintet
We present the first Galaxy Evolution Explorer (GALEX) UV images of the well-known interacting group of galaxies, Stephan's Quintet (SQ). We detect widespread UV emission... -
Optical and IUE spectra of NGC 7026
We investigated spectroscopic data of the extended planetary nebula NGC 7026 in the wavelengths 3700-10050{AA}, secured with the Hamilton Echelle Spectrograph at Lick... -
EUV spectrum of solar active region from SERTS-97
Goddard Space Flight Center's Solar EUV Research Telescope and Spectrograph was flown on 1997 November 18, carrying an intensified CCD detector and a multilayer-coated toroidal... -
UV and optical line variations in {epsilon} Persei
The rapid variable star, {epsilon} Per (B0.5 IV-III), displays the largest amplitude profile fluctuations known among the growing number of massive, spectrum-variable stars....
