Halpha and other EWs of LAMOST M-type stars
We have used the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) low-resolution and medium-resolution spectroscopic surveys to explore the chromospheric... -
The GNRIS-Distant Quasar Survey (GNRIS-DQS)
We present spectroscopic measurements for 226 sources from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-DQS). Being the largest uniform, homogeneous survey... -
Stellar bow shock nebulae spectroscopic obs.
Arcuate mid-infrared nebulae known as stellar bow shock nebulae (SBNe) have been previously hypothesized to be supported by the strong stellar winds and/or luminosity of massive... -
Variable MgII NALs in SDSS DR14
Compared to high ionization CIV absorption lines, variable MgII absorption lines are rare. Using spectra from the Sloan Digital Sky Survey, we investigate the variations in MgII... -
R-Process Alliance: metal-poor star spectroscopy
This compilation is the fourth data release from the R-Process Alliance (RPA) search for r-process-enhanced stars and the second release based on "snapshot" high-resolution... -
Massive stars in APOGEE2 Survey. III.
We have applied the semi-empirical spectral analysis, developed by the Sloan Digital Sky Survey (SDSS)-IV/Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE2)... -
QSO properties from SDSS. II. The first two years
This work aims to measure the properties of continuum and emission lines around CIV, MgII, H{beta}, and H{alpha} for the quasars observed by the extended Baryon Oscillation... -
M-type star magnetic activities from LAMOST & Kepler
We performed a statistical study of magnetic activities of M-type stars by combining the spectra of LAMOST DR5 with light curves from the Kepler and K2 missions. We mainly want... -
CANDELS/SHARDS multiwavelength cat. in GOODS-N
We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts,... -
A complete sample of broad-line AGN from SDSS-DR7
A new, complete sample of 14584 broad-line active galactic nuclei (AGNs) at z<0.35 is presented, which are uncovered homogeneously from the complete database of galaxies and... -
SiIV and NV absorption line SDSS quasar systems
Using the quasar spectra from the Sloan Digital Sky Survey and with variable C IV absorption line systems, we measure the Si IV and N V absorption line systems. We obtain 50... -
MgII-BAL quasar variability in SDSS spectra
We present absorption variability results for 134 bona fide MgII broad absorption-line (BAL) quasars at 0.46<=z<=2.3 covering days to ~10yr in the rest frame. We use... -
Am stars from LAMOST DR5
The Large Sky Area Multi-Object Fibre Spectroscopic Telescope data release 5 (DR5) released more than 200,000 low-resolution spectra of early-type stars with a signal-to-noise... -
LAMOST Quasar Survey: Data Releases 4 and 5
We present Data Releases 4 and 5 of the quasar catalog from the quasar survey by the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST), which includes quasars... -
LEGA-C DR2: galaxies in the COSMOS field
We present the second data release of the Large Early Galaxy Astrophysics Census (LEGA-C), an ESO 130-night public spectroscopic survey conducted with VIMOS on the Very Large... -
CIV NAL systems from SDSS-DR14 quasar spectra
Using the quasar spectra from the Sloan Digital Sky Survey, all with two-epoch to six-epoch observations, we search for CIV{lambda}{lambda}1548,1551 narrow absorption doublets... -
Absorption lines in 21 Lyn A-type star
We present a catalog of absorption lines in the z', Y, and J bands that we identified in 21 Lyn, a slowly rotating A0.5V star. We detected 155 absorption features in the... -
IGRINS spectral library
We present a library of high-resolution (R~45000) and high signal-to-noise ratio (S/N>=200) near-infrared spectra for stars of a wide range of spectral types and luminosity... -
CIV narrow absorption line systems in SDSS-DR14
We assemble 207 variable quasars from the Sloan Digital Sky Survey, all with at least 3 observations, to analyze CIV narrow absorption doublets, and obtain 328 CIV narrow... -
Absorption features in SDSS. I. MgII abs. doublets
Using the SDSS spectra of quasars included in the DR7Q or DR12Q catalogs, we search for MgII{lambda}{lambda}2796,2803 narrow absorption doublets in the spectra data around...
