TEUV corrects synthetic stellar fluxes for interstellar absorption for wavelengths smaller than 91.1 nm. It simulates radiative bound-free absorption of the ground states of H,...

Split spectra from the CALIFA DR3 cubes. This service serves one spectrum each per pixel in each cube where there is at least one valid spaxel. Where both V500 and COMB data is...

These spectra are optical follow-up observations of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field-South (CDFS) using FORS.

Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and...

We present chemical abundances for 21 elements (from Li to Eu) in 150 metal-poor Galactic stars spanning -4.1<[Fe/H]<-2.1. The targets were selected from the SkyMapper...

Tidal interactions between galaxies often give rise to tidal tails, which can harbor concentrations of stars and interstellar gas resembling dwarf galaxies. Some of these tidal...

The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies selected to have Iab...

This table contains basic metadata as well as the spectra from the Digital First Byurakan Survey (DFBS).

The First Byurakan Survey (FBS) is the largest and the first systematic objective prism survey of the extragalactic sky. It covers 17,000 sq.deg. in the Northern sky together...

The Visual and Infrared Mapping Spectrometer (VIMS) instrument onboard the Cassini spacecraft observed the system of Saturn, acquiring spectral cubes in the range 0.4-5.2...

The Data Release Seven of LAMOST Low-Resolution Spectroscopic Survey (LRS). The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a Chinese national...

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...

We take advantage of the publicly available LEGA-C spectroscopic survey to measure the stellar population properties of 140 individual massive and passive galaxies at z~0.7. We...

K2-136 is a late-K dwarf (0.742{+/-}0.039M{sun}) in the Hyades open cluster with three known, transiting planets and an age of 650{+/-}70Myr. Analyzing K2 photometry, we found...

The dynamical states of molecular clouds may affect the properties of the stars they form. In the vicinity of the Trifid Nebula (d=1180+/-25pc), the main star cluster (Trifid...

We present a catalog of optical and infrared identifications (ID) of X-ray sources in the {AKARI} North Ecliptic Pole (NEP) Deep field detected with Chandra covering ~0.34deg^2^...

A sample of quasars has been recently assembled to investigate the non-linear relation between their monochromatic luminosities at 2500{AA}, and 2keV and to exploit quasars as a...

Most ultraluminous X-ray sources (ULXs) are thought to be powered by super- Eddington accretion on to stellar-mass compact objects. Accretors in this extreme regime are...

Spectra from surveys hosted by Data Central. Most spectra were taken with the multi-object spectroscopy facilities 2dF (Anglo-Australian Telescope) and 6dF (UK Schmidt Telescope).

We present the results from a systematic study of temporal variation of stellar activity in young late-type stars. We used multi-epoch LAMOST (Large sky Area Multi-Object fiber...
