[csp] "Radioastronomy in the VO" session at IVOA interop in October

Fri Sep 6 23:42:09 CEST 2019

Hi Bruno,

Thanks for organising this session.

I'm happy to contribute a talk on our implementation experience, whether that be CSIRO's radio astronomy archives, their VO interfaces and what usage we have seen so far of the VO services, or something more focussed such as supporting visibilities/measurement sets or pulsar data in ObsCore etc.

Mark's point about Faraday rotation measure data products is one which we know there is demand for but do not have a solution for yet, so I'd be very interested in that topic too.

Cheers,
James Dempsey

Thanks Mark!

Indeed, that sounds like a very interesting point for discussion, mostly once those who understand it well explain for the non-radioastronomers in the room. 8)

Best regards,

Hi Bruno,

That sounds like an excellent plan, and it's good timing I will be able to attend the IVOA meeting in person this time. One radio astronomy specific thing that has come up recently in discussions of radio surveys is the question of how to deal with Faraday rotation measure data produced by rotation measure synthesis techniques, both in catalogs and image cubes with a rotation measure axis. So this might be an interesting item to add to the discussion.

Cheers,
Mark

Dear all,

As some of you might know, the International Virtual Observatory Alliance (IVOA<http://ivoa.net/>) is meeting from the 11th to the 13th of October at the DOTliveplanetarium in Groningen (meeting page here<https://www.adass2019.nl/ivoa/ivoa-2/>). Given the vast experience in radioastronomy in the area and the potential availability of several expert radioastronomers in the area, we had the idea of organizing a “Radioastronomy in the VO” session to examine together the availability to radio data in the VO and try to identify the simplest steps to connect both worlds or at least to move slightly in the right direction. We would be talking about a 1.5 to 2 hour plenary session during the IVOA interop meeting in Groningen with a few small presentations to set the context and a discussion on what to do next. We would first like to invite you all to this session (either in person or remotely, giving a talk or just participating in the discussion) and would like to ask how do you think this discussion could be more useful to both parties. We will take care of all the logistics of the session.

An earlier similar discussion already took place in the context of the ESCAPE project and the notes can be found here<https://www.asterics2020.eu/dokuwiki/doku.php?id=open:wp4:wp4techforum5:radiointhevo>. Therefore, we could start the session with a summary of the conclusions from the earlier meeting by e.g. Francois Bonnarel from CDS and then try to identify the next steps to make all the Radio data easily available to the VO world and viceversa. We are very much aware that this is a long-standing goal from the VO but we are determined to give it a second push now that many interfaces and protocols have matured substantially in the VO side.

Any further comments and thoughts from any of you, or any recommendation to contact any other people in the data providers world for radioastronomy would be very useful too. I look forward hearing from you about this.

This is the list of people that I have addressed this message to, together with their affiliation and potential role in the IVOA:
