UV Catalogues


The Joint Center for Ultraviolet Astronomy (JCUVA) shares the management of the Spektr-UF / WSO-UV Science Program. The WSO-UV SCC will also host the Mission Data archive (MDA) . 

As part of these activities, we will list below catalogues of UV sources, provided either by UV missions or by the community.

T Tauri Stars observed with I.U.E. Catalogue

T Tauri Stars (TTS) are low mass (M≤ 1M⊙) pre-main sequence (PMS) stars. They are often classified into two main sub-classes: classical TTS (cTTS) and weak line TTS (wTTS). This classification is based on the strength of the Hα line (W(Hα ) ≥ 10 Å  for cTTS and W(Hα ) ≤ 10 Å  for wTTS) that was taken primitively as a good tracer of their magnetic activity (and youth).

Herbig-Haro Objects Observed with I.U.E Catalogue

Herbig-Haro Objects (HHOs) are shock-excited nebulosities observed in star forming regions. They are powered by the energy released in the shocks between outflows from pre-main-sequence stars and interstellar gas (or previous ejecta)



UV Background Fluctuation Index from GalEX

Catalog containing the Ultraviolet Background Fluctuations Index from the all sky survey run by the Galaxy Evolution Explorer in the far ultraviolet (FUV) band (-intbgsub files).



Synthetic photometry in the GalEX bands of stellar sources observed with I.U.E.

The Galaxy Evolution Explorer (GALEX) has produced the largest photometric catalogue of ultraviolet (UV) sources. As such, it has defined the new standard bands for UV photometry: the near UV band (NUV) and the far UV band (FUV). However, due to brightness limits, the GALEX mission has avoided the Galactic plane which is crucial for astrophysical research and future space missions.


GalEX Catalogues of UV sources produced by Luciana 

GALEX, the GALaxy Evolution eXplorer, performed the first extensive sky surveys at Ultraviolet wavelengths, filling the last gap so that our view of the sky is complete across the electromagnetic spectrum. The imaging surveys resulted in almost 600 million source measurements in two UV bands, far-UV and near-UV.
