WR galaxies and HII regions catalog
We present a new compilation of Wolf-Rayet (WR) galaxies and extra-galactic HII regions showing broad He II {lambda}4686 emission drawn from the literature. Relevant information... -
alpha & Fe abundances in the giant stellar stream
We present the first measurements of [Fe/H] and [{alpha}/Fe] abundances, obtained using spectral synthesis modeling, for red giant branch stars in M31's giant stellar stream... -
Spectrophotometric redshifts of GOODS galaxies
We investigate the accuracy of 4000{AA}/Balmer-break based redshifts by combining Hubble Space Telescope (HST) grism data with photometry. The grism spectra are from the Probing... -
First release of the MaNGA Stellar Library (MaStar)
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength range... -
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... -
OI abs. search in Keck and VLT spectra of 199 QSOs
We present a survey for metal absorption systems traced by neutral oxygen over 3.2<z<6.5. Our survey uses Keck/ESI and VLT/X-Shooter spectra of 199 QSOs with redshifts up... -
Ultracool SpeXtroscopic survey. I. M7-L5 sample
We present a volume-limited, spectroscopically verified sample of M7-L5 ultracool dwarfs (UCDs) within 25pc. The sample contains 410 sources, of which 93% have trigonometric... -
Cepheids from VVV in the southern Galactic midplane
The far side of the Milky Way's disk is one of the most concealed parts of the known universe due to extremely high interstellar extinction and point-source density toward low... -
Cand. young OB stars from GALEX & Gaia DR2
We combine Galaxy Evolution Explorer and Gaia DR2 catalogs to track star formation in the outskirts of our Galaxy. Using photometry, proper motions, and parallaxes we identify a... -
Optical and UV follow-up of 1ES 1927+654
We study the sudden optical and ultraviolet (UV) brightening of 1ES1927+654, which until now was known as a narrow-line active galactic nucleus (AGN). 1ES 1927+654 was part of... -
Lyman cont. luminosity of SDSS quasar pairs at z~3
We have used spectra of 181 projected quasar pairs at separations <=1.5' from the Sloan Digital Sky Survey Data Release 12 in the redshift range of 2.5-3.5 to probe the... -
Medium-band photometry RM of 5 nearby AGNs
Reverberation mapping (RM) is one of the most efficient ways to investigate the broad-line region around the central supermassive black holes of active galactic nuclei (AGNs). A... -
Exploring 6 AGN dusty torus models. II.
This is the second in a series of papers devoted to exploring a set of six dusty models of active galactic nuclei (AGN) with available spectral energy distributions. These... -
Astrochemical study along M83 circumnuclear ring
We report an astrochemical study on the evolution of interstellar molecular clouds and consequent star formation in the center of the barred spiral galaxy M83. We used the... -
PAH features of star-forming gal. using Spitzer/IRS
Polycyclic aromatic hydrocarbon (PAH) emission has long been proposed to be a potential star formation rate indicator, as it arises from the photodissociation region bordering... -
VLA obs. of the H2O maser source G25.65+1.05
The source G25.65+1.05 (RAFGL7009S, IRAS 18316-0602) is the least studied of the three regions of massive star formation known to show exceptionally powerful H_2_O maser bursts.... -
HaloSat targets to study the hot Galactic halo
HaloSat is a small satellite (CubeSat) designed to map soft X-ray oxygen line emission across the sky in order to constrain the mass and spatial distribution of hot gas in the... -
OGLE-III Mira variables in the Magellanic Clouds
We present Period-Luminosity and Period-Luminosity-Color relations at maximum light for Mira variables in the Magellanic Clouds using time-series data from the Optical... -
RELICS: Reionization Lensing Cluster Survey
Large surveys of galaxy clusters with the Hubble Space Telescope (HST) and Spitzer, including the Cluster Lensing And Supernova survey with Hubble and the Frontier Fields, have... -
Spectra & HST obs. of gal. in 1ES1553+113 field
The relationship between galaxies and the state/chemical enrichment of the warm-hot intergalactic medium (WHIM) expected to dominate the baryon budget at low-z provides...
