UV to NIR spectra of the QSO 2MASS J15165323+1900482
We present detailed studies of the partially obscured quasar 2MASSJ151653.23+190048.2 with continuous broadband spectrophotometry from near-infrared (NIR) through optical to... -
ASTRAL: abundance analysis of HR 465
This paper presents the results of the spectrum analysis of the B-type magnetic chemically peculiar star HR465. HR465 shows unusual abundance patterns that vary with a period of... -
BH masses and bulge+disk UV-3.6um color relations
The tight correlations between supermassive black hole (SMBH) mass (MBH) and the properties of the host galaxy have useful implications for our understanding of the growth of... -
Component structure in the neighborhood of IC 443
We present the results of a detailed investigation into the physical conditions in interstellar material interacting with the supernova remnant (SNR) IC443. Our analysis is... -
Properties of atomic lines in 51 Oph UV spectra
We measured 304 absorption features in the ultraviolet and visible spectra of the star 51 Oph, which is known to have a debris disk with a high inclination. We analyzed the... -
Column densities from HST/COS SiIV AGN sight lines
We develop a kinematical model for the Milky Way SiIV-bearing gas to determine its density distribution and kinematics. This model is constrained by a column density line-shape... -
Iron element abundances in 3 very metal-poor stars
We have obtained new detailed abundances of the Fe-group elements Sc through Zn (Z=21-30) in three very metal-poor ([Fe/H]~-3) stars: BD+03 740, BD-13 3442, and CD-33 1173.... -
Lya galaxies in 3 CFHTLS overdense regions
We have carried out follow-up spectroscopy on three overdense regions of g- and r-dropout galaxies in the Canada-France-Hawaii Telescope Legacy Survey Deep Fields, finding two... -
Equivalent widths of giants in the GC NGC3201
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GCs) has investigated multiple stellar populations by means of the "chromosome map" (ChM)... -
COS CGM compendium (CCC). III. z<=1 Ly{alpha} syst.
We characterize the metallicities and physical properties of cool, photoionized gas in a sample of 152 z<=1 strong Ly{alpha} forest systems (SLFSs, absorbers with 15 -
REQUIEM survey. I. Ly{alpha} halos around QSOs
The discovery of quasars a few hundred megayears after the Big Bang represents a major challenge to our understanding of black holes as well as galaxy formation and evolution.... -
Ly{alpha} obs. of low-mass stars Ross 825 & 1044
The discovery of habitable zone (HZ) planets around low-mass stars has highlighted the need for a comprehensive understanding of the radiation environments in which such planets... -
Global energetics of solar flares. IX.
A more accurate analytical solution of the vertical-current approximation nonlinear force-free field (VCA3-NLFFF) model is presented that includes, besides the radial (Br) and... -
Best-fit emission-line properties in NGC 5775
The structure and kinematics of gaseous, disk-halo interfaces are imprinted with the processes that transfer mass, metals, and energy between galactic disks and their... -
Short-duration stellar flares from GALEX & Kepler
We report on a population of short-duration near-ultraviolet (NUV) flares in stars observed by the Kepler and Galaxy Evolution Explorer (GALEX) missions. We analyzed the NUV... -
Column densities of CGM absorption lines
We investigate the geometric distribution of gas metallicities in the circumgalactic medium (CGM) around 47, z<0.7 galaxies from the "Multiphase Galaxy Halos" Survey. Using a... -
Space telescope RM project. VIII. NGC5548 HST sp.
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC 5548 obtained with the Hubble Space Telescope during the 6 month reverberation mapping campaign in 2014. Our model... -
Opt. & UV evolution of the TDE iPTF15af
We present multiwavelength observations of the tidal disruption event (TDE) iPTF15af, discovered by the intermediate Palomar Transient Factory survey at redshift z=0.07897. The... -
The COS CGM Compendium (CCC). II. Lyman limit syst.
We present the results from our COS circumgalactic medium (CGM) compendium (CCC), a survey of the CGM at z<~1 using HI-selected absorbers with 15<logN_HI_<19. We focus... -
OI, GeII, KrI & H abundances from HST UV spectra
In a survey of archived ultraviolet spectra of 100 stars recorded by the echelle spectrograph of the Space Telescope Imaging Spectrograph on the Hubble Space Telescope, we...
