Bochum Galactic Disk Survey (BGDS) images
The Bochum Galactic Disk Survey is a project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been... -
Photometric redshifts in Stripe 82
This is a catalogue of photometric redshifts of galaxies in the Stripe 82 obtained when morphology (galaxy size, ellipticity, Sérsic index, and surface brightness) are included... -
BGDS Mean Photometry Cone Search
Extracted sources from the Bochum Galactic Disk Survey. We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also,... -
Bochum Galactic Disk Survey (BGDS) light curves
This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey; several million light curves are provided in the SDSS i and r bands. The lightcurves... -
OpC study with UBVRI and Gaia EDR3
We present the results of the investigation of 58 open clusters using UBVRI CCD photometry (Johnsons-Cousins system) and Gaia eDR3 data. The membership probability of the stars... -
Variable stars on Leo II dSph
Pulsating variable stars are invaluable tracers for reconstructing the star formation history and chemical evolution of their host galaxies. In this work, we explore the... -
Magnitudes of five SNe Ibn
We present the photometric and spectroscopic analysis of five Type Ibn supernovae (SNe): SN 2020nxt, SN 2020taz, SN 2021bbv, SN 2023utc, and SN 2024aej. These events share key... -
Magnetic activity based on LAMOST and Kepler
Stellar magnetic activity is an interesting phenomenon in late-type stars. We use the medium-resolution spectroscopic observations of 406069 late-type stars from LAMOST to... -
Study of NGC 381, NGC 2360 and Berkeley 68
We present UBVR_c_I_c_ photometric study of three intermediate age open star clusters NGC381, NGC2360, and Berkeley68 (Be68). We examine the cluster membership of stars using... -
MEGARA-GTC stellar spectral library I
MEGARA (Multi Espectrografo en GTC de Alta Resolucion para Astronomia) is an optical (3650-9750{AA}), fibre-fed, medium-high spectral resolution (R=6000, 12000 and 20000)... -
Faint radio source population at 15.7GHz - IV
We present 15-GHz Karl G. Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7GHz from the Tenth Cambridge (10C) survey. 67 out of the 95... -
Faint Standards for UKIDSS and VISTA ZYJHK
The currently defined 'United Kingdom Infrared Telescope (UKIRT) Faint Standards' have JHK magnitudes between 10 and 15, with K_median_=11.2. These stars will be too bright for... -
SN 2016gsd: an unusually luminous supernova
We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V=-19.95+/-0.08, this object is one of the brightest Type II... -
Spectroscopic observations on M4 AGB stars
Several recent spectroscopic investigations have presented conflicting results on the existence of Na-rich asymptotic giant branch (AGB) stars in the Galactic globular cluster M... -
Berkeley 51 UBV photometry
The heavily obscured open cluster Berkeley 51 shows characteristics typical of young massive clusters, even though the few previous studies have suggested older ages. We combine... -
Multiwavelength study of HII region S311
We present a multiwavelength investigation of the young stellar population and star formation activities around the HII region Sharpless 311. Using our deep near-infrared... -
SN 2013ej light curves 1 to 450d after explosion
We present optical and near-infrared photometric and spectroscopic observations of SN 2013ej, in galaxy M74, from 1 to 450 d after the explosion. SN 2013ej is a hydrogen-rich... -
47 Tuc sub-giant branch chemical abundances
The globular cluster 47 Tuc exhibits a complex sub-giant branch (SGB) with a faint-SGB comprising only about the 10 per cent of the cluster mass and a bright-SGB hosting at... -
Edinburgh-Cape Blue Object Survey. Zones 4-6
Results for the remaining zones of the Edinburgh-Cape (EC) Blue Object survey are presented. These are incomplete, but lie in that part of the South Galactic Cap between 50deg... -
Optical photometry of nova V5588 Sgr
The outburst of Nova Sgr 2011 N.2 (=V5588 Sgr) was followed with optical and near-IR photometric and spectroscopic observations for 3.5 yr, beginning shortly before the maximum....
