I cannot find source 3XMM J215022.4–055108

I cannot find source 3XMM J215022.4–055108, which is the topic of a recent nature paper about a black hole hosting stellar cluster: https://www.nature.com/articles/s41550-018-0493-1

Being this an XMM-Newton source probably from the 3XMM catalogue, shouldn't it be possible to find it directly by name in ESASky? I cannot find in SIMBAD nor in the XMM archive..

Dear Becky,


ESASky and the XMM-Newton Science Archive use the name resolver from SIMBAD, CDS, to find astronomical sources. If the source is not in SIMBAD, the tools will not be able to find it. As you said, this source indeed is not in SIMBAD. As a work around, these types of sources have the coordinates in their name, I'd suggest searching for the source taking the numbers from the name '215022.4–055108' and searching for the source by coordinates: 21 50 22.4 -05 51 08
The source can then be identified in ESASky by loading the XMM-Newton 3XMM EPIC and Chandra CSC1.1 catalogues.

The ESDC are working on solutions to allow users to search for objects that are in ESA catalogues, we hope to add this functionality to ESASky and our archives soon.

Kind regards,

Deborah
