S-type stars from LAMOST MRS DR9 with Gaia DR2 data
In this paper, we report on 606 S-type stars identified from Data Release 9 of the LAMOST medium-resolution spectroscopic (MRS) survey; 539 of them are reported for the first... -
Variable hot subdwarf from Gaia DR2 and TESS
Hot subdwarf stars are mostly stripped red giants that can exhibit photometric variations due to stellar pulsations, eclipses, the reflection effect, ellipsoidal modulation, and... -
HFF cluster observations of z~4-8 galaxies
We constrain the rest-UV size-luminosity relation for star-forming galaxies at z~4 and z~6, 7, and 8 identified behind clusters from the Hubble Frontier Fields (HFF) program.... -
Above-horizontal-branch (AHB) stars in Gal. GCs
We have carried out a search for above-horizontal-branch (AHB) stars-objects lying above the horizontal branch (HB) and blueward of the asymptotic giant branch (AGB) in the... -
Type Ia SNe with galaxy host properties
More luminous Type Ia supernovae prefer less massive hosts and regions of higher star formation. This correlation is inverted during width-color-luminosity light-curve... -
Galaxy-absorber pairs for low-z QSO sightlines
We present a study of candidate galaxy-absorber pairs for 43 low-redshift QSO sightlines (0.06<z<0.85) observed with the Hubble Space Telescope/Cosmic Origins Spectrograph... -
Ultra-diffuse galaxies with spectroscopic obs.
We present new redshift measurements for 19 candidate ultra-diffuse galaxies (UDGs) from the Systematically Measuring Ultra-Diffuse Galaxies (SMUDGes) survey after conducting a... -
HectoMAP Cluster Survey: clusters & BCGs
We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between brightest cluster galaxies (BCGs)... -
M83 X-ray binary classifications from HST
Building on recent work by Chandar+ (2020, J/ApJ/890/150), we construct X-ray luminosity functions (XLFs) for different classes of X-ray binary (XRB) donors in the nearby... -
Massive white dwarfs in young star clusters
We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was (1) to provide... -
RELICS 6<~z<=8 galaxies with Spitzer & HST obs.
We present constraints on the physical properties (including stellar mass, age, and star formation rate) of 207 6<=z<=8 galaxy candidates from the Reionization Lensing... -
The local universe with ZTF. I. Ca-rich gap transients
Using the Zwicky Transient Facility alert stream, we are conducting a large spectroscopic campaign to construct a complete, volume-limited sample of transients brighter than... -
X-SHOOTER/ALMA QSOs at 5.78<z<7.54. I. NIR sp.
We present X-SHOOTER near-IR spectroscopy of a large sample of 38 luminous (M_1450_=-29.0 to -24.4) quasars at 5.78<z<7.54, which have complementary [CII]158{mu}m... -
UV to visible-light observations of SN 2018fif
High-cadence transient surveys are able to capture supernovae closer to their first light than ever before. Applying analytical models to such early emission, we can constrain... -
Spectroscopy of quiescent gal. in 9 lensing clusters
We measure the central stellar velocity dispersion function for quiescent galaxies in a set of nine northern clusters in the redshift range 0.18<z<0.29 and with strong... -
INT monitoring of Local Group. I. Andromeda I
An optical monitoring survey in nearby dwarf galaxies was carried out with the 2.5m Isaac Newton Telescope. Fifty-five dwarf galaxies and four isolated globular clusters in the... -
A comprehensive statistical study of gamma-ray bursts
In order to obtain an overview of gamma-ray bursts (GRBs), we need a full sample. In this paper, we collected 6289 GRBs (from GRB 910421 to GRB 160509A) from the literature,... -
Milky Way satellite census. I. DES & PS1
We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and... -
Teff and metallicities of M dwarfs in APOGEE DR14
M dwarfs have enormous potential for our understanding of structure and formation on both Galactic and exoplanetary scales through their properties and compositions. However,... -
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...
