Dear all,

We warmly invite you and your colleagues to participate in the
"Synergies with Radio Astrometry" session during the Gaia Symposium
(GREAT meeting), at the EWASS 2017, 26-30 June in Prague.

Currently, both radio and optical astrometry can reach accuracies of
the order of 10 micro arcseconds, allowing Galactic scale studies
through precise distance measurements. In this respect, systematic
radio astrometry programs, such as the Bar-and-Spiral-
Structure-Legacy survey and the VLBI-Exploration-of-Radio-Astrometry,
are currently assessing distance and proper motion estimates of
several hundreds of star-forming regions across our Galaxy, while the
first optical Tycho-Gaia astrometry was released in September 2016.

The session is dedicated to bringing together the radio and optical
astrometry community to learn from each other, discuss and start new
fruitful collaborations. The session will include a Radio Astrometry
review talk, and several contributed talks. For the latter we invite
people to submit an abstract presenting their latest groundbreaking
results in radio and optical astrometry, and possible combinations of
the two methods. For example, a precise cross matching of radio and
optical sources will allow combined studies of large-scale structures
of our Galaxy, up to the Galactic spiral arms, as well as a
substantial revision of the International Celestial Reference Frame.
Discussions on the scientific merit of combining radio and optical
astrometry are strongly encouraged.

Review talk: Radio Astrometry by Mareki Honma (NAOJ)
Scientific Organizing Committee: Kazi Rygl (INAF-IRA), Alberto Sanna
(MPIfR), Huib Jan van Langevelde (JIVE/Sterrewacht Leiden), Francois
Mignard (OCA), Géraldine Bourda (LAB), Teresa Antoja (ICCUB), Nobuyuki
Sakai (NAOJ)

The Gaia Symposium will take place on 26-27 June. Registration is
handled directly through the EWASS pages at
http://eas.unige.ch/EWASS2017/registration.jsp  with early
registration closing 26 Apr 2017.
** The abstract submission deadline is 8 March 2017 **


At this stage all those wishing to present are invited to signup with
some details of their talk or poster presentation idea.

Please, first, submit your abstract into the EWASS system (which keeps
track of abstracts across all the various meetings going on that
week). You'll find this page at

... and then ...

there is a page for each of the themed sessions linked from the Gaia
symposium wiki at http://great.ast.cam.ac.uk/Greatwiki/GreatMeet-PM10

Thus, choose which session most fits your presentation topic and add
your abstract to the page at:

Gaia DR1: Highlight Science -⁠ Session 1
Gaia /⁠ GREAT Status -⁠ Session 2
Gaia DR1 science -⁠ Session 3
Gaia networking, synergies with other surveys -⁠ Session 4
Upcoming Gaia DR2 and Gaia Processing -⁠ Session 5
Special session: synergies with radio astrometry -⁠ Session 6

Adding your abstracts in this way to the wiki, helps all to see what
sort of talks are being submitted to the Gaia Symposium!

All submissions received by *8th March 2017* will be considered, with
the final programme being drawn up and published by 10th April 2017.

The outline agenda (and eventual full programme) is on the meeting
wiki page at http://great.ast.cam.ac.uk/Greatwiki/GreatMeet-PM10

Note -⁠ the EAS provide some support to attend the meeting -⁠ for
details of that please see http://eas.unige.ch/ewass.jsp -⁠ look under
'Grant Request' for the EWASS2017 meeting. Deadline for requesting
that support is 8th March 2017.

Looking forward to seeing you in Prague,
Kazi Rygl on behalf of the synergies with radio astrometry SOC
