An archive of optical and near-infrared spectra of strongly lensed quasars and the lensing galaxies. The spectra are resolved to about a few Ångstroms and are flux-calibrated....

This dataset contains spectroscopic observations of 29 globular clusters in the Magellanic Clouds and the Milky Way performed with VLT/X-shooter over eight full nights.

TGRED is a tool to calculate the gravitational redshift and the respective radial velocity.

First Byurakan survey plate scan service

The Calar Alto Legacy Integral Field Area (CALIFA) survey provides spatially resolved spectroscopic information for 667 galaxies, mainly within the local universe (0.005 < z...

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...

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...

SSHADE bandlist library.

SSHADE spectra library.

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).

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

This study introduces a line list for the abundance analysis of F-and G-type stars across the 4,080-9,675{AA} wavelength range. A systematic search employing lower excitation...

We present a list of tailed radio galaxies using the Tata Institute of Fundamental Research (TIFR) Giant Metrewave Radio Telescope (GMRT) Sky Survey Alternative Data Release 1...

In order to explore how the ubiquitous stochastic low-frequency (SLF) variability of O-type stars is related to various stellar characteristics, we compiled a sample of 150...

Near-infrared spectra from the IRTF/SpeX and Blanco/ARCoIRIS telescope/instrument combinations are used for spectroscopic classification, to measure radial velocities, and for...

Expectations for an imminent new outburst of the recurrent symbiotic nova T CrB are mounting, initiated by the discovery in 2015 of a new super-accretion phase (SAP), which is...

Active galactic nuclei (AGN) stand as extreme X-ray emitters where disk-corona interplay shapes their spectral energy distribution. The soft X-ray excess, a unique feature of...

NGC 362 is a non-common Type II Galactic globular cluster, showing a complex pseudo two-colour diagram or 'chromosome map'. The clear separation of its stellar populations in...

This resource provides a compiled dataset of Galactic planetary nebulae derived from absolute optical spectroscopy and supplemented by selected values from the literature. Based...

We study a catalogue of over 130 emission-line galaxies with matched near infra-red (NIR) and optical spectra, where we examine the relationship between the respective nuclear...
