New Concept: Ultraluminous X-ray source

[katieefrey]

Name the new concept Ultraluminous X-ray source

Describe the concept Ultraluminous X-ray source, also called Ultra-luminous X-ray sources, or ULX (also called super-Eddington sources) : https://en.wikipedia.org/wiki/Ultraluminous_X-ray_source Could be narrower term for http://astrothesaurus.org/uat/1822

Please include any additional comments/feedback Suggestion from Sebastien Derriere, Observatoire de Strasbourg

(edited because I copied the wrong description)

other related concepts? what are their relationships

Ultraluminous supersoft sources (ULSs) are X-ray sources 2019MNRAS.490.4804C

luminous supersoft X-ray source (SSXS, or SSS) is an astronomical source that emits only low energy https://en.wikipedia.org/wiki/Super_soft_X-ray_source

Supersoft sources

I think these three are all synonymous, but possibly not synonymous with ULXs

Pulsating ULXs "Motivated by the recent discoveries that six Ultraluminous X-ray Sources (ULXs) are powered by highly super-Eddington X-ray pulsars, we searched for additional pulsating ULX (PULX) candidates by identifying sources that exhibit long-term flux variability of at least an order of magnitude (a common feature seen in the 6 known PULXs, which may potentially be related to transitions to the propeller regime)." -- 2019MNRAS.tmp.2630S

Dr. Matteo Bachetti of the National Institute for Astrophysics also agrees that the UAT needs "Ultra luminous x-ray sources."

Frank Timmes, AAS High Energy editor, is in favor of adding ULX as a concept, with the other items mentioned here added as synonyms.

Adding as child term of "x-ray sources" (1822)
