8th VVV Science Meeting, Edinburgh, 2017

The 8th VVV Science Meeting at the Royal Observatory, Edinburgh

3- 5 July, 2017

8th VVV Science Meeting, July 2017, Edinburgh, UK

Vista Variables in the Via Lactea (VVV) eXtended survey (VVV-X)

For the past 6 years, the ESO Public Survey VISTA Variables in the Via Láctea (VVV) has been mapping the IR variability of the Milky Way bulge and southern mid-plane. ESO has recently approved our proposal to extend the survey, thus enhancing its long lasting legacy. The VVV eXtended (VVVX) survey is aimed to cover the gaps left between the VVV and VHS areas. It will also extend the VVV time-baseline, enabling variability and proper motion measurements in the optically obscured regions where most observations are strongly limited by extinction, using a total of 1998 hr of VISTA and covering an area of 1700 sq. deg. of the Southern sky.

The meeting in Edinburgh

The 8th VVV meeting will take place in the Royal Observatory Edinburgh, Scotland, UK. More information about the ROE can be found here: ROE info

The Edinburgh meeting will be focused on discussing science case priorities for the next years, revising the survey strategy after the first year of VVVX observations and establishing spectroscopic follow-up strategies.

Registration for the workshop is open. A fee of GBP 85.00 will be charged to all participants and must be paid before 01 May following the information in the registration page. The fee covers coffee breaks and lunch during the meeting as well as group dinner for the evening of 3 and 4th of July.

The meeting will include only contributed talks and posters. You can submit your title and abstract following the registration link. Accepted talks and program will be released by April 1st.
