Scientific Rationale

For the past 10 years (!!!), the ESO Public Survey VISTA Variables in the Via Lactea (VVV), and its second phase, the VVV eXtended Survey (VVVX), have been mapping the IR variability of the Milky Way bulge and southern mid-plane (vvvsurvey.org). Within the existing 562 deg2 covered by the VVV area, we are producing a 5-D map of the surveyed region by combining positions, distances and proper motions of well-understood distance indicators such as red clump stars, RR Lyrae and Cepheid variables in order to unveil the inner structure of the Milky Way. The VVV+VVVX catalogues, covering in total 1700 deg2 in total,currently in their first forms, will complement those from the Gaia space mission with very red sources and will feed spectroscopic targets for the forthcoming ESO high-multiplex spectrographs MOONS and 4MOST. For multi-wavelength analysis, VVV+VVVX can be coupled with ATLASGAL, GLIMPSE, DECAPS, UKIDSS-GPS, Gaia, VPHAS, Chandra X-ray, and other Galacitic surveys. In the time domain, it can be coupled with ZTF, LSST, IPAC/Neowise, OGLE and TESS/K2.

The Meeting is being planned to include contributed talks, poster sessions and group discussions on High-Level Science Products, and coordinating with other surveys.

Venue

Hilo is a town on Hawai'i, commonly called the Big Island, in the state of Hawai'i. It’s known for Wailuku River State Park, featuring Waianuenue, or Rainbow Falls, with its colorful mist effects. The bubbling basalt-lava rock pools known as the Boiling Pots are nearby. To the south is Hawaii Volcanoes National Park, home to rainforests and the active Kilauea and Mauna Loa volcanoes.

Hilo also is the home base of 10 of the 12 observatories atop the volcano Maunakea. 

The United Airline flight from Los Angeles to Hilo is the only direct flight coming from the U.S. mainland. However, you also have two other options. One is to transit through Honolulu (which has flights coming from many places in the world), and get the last leg to Hilo served by Hawaiian Airlines. The other is to fly to Kona via a direct flight from many cities in the U.S., Canada, Japan, and Korea.

Rooms have been reserved at the Hilo Hawaiian Hotel with preferential rates (135.00$/night + taxes).

It is highly recommended to arrange transportation ahead of time. There are many car rental options in Hilo.

Here is a Visitor's Guide we share with our observers, in case it helps!

U.S.A. Visa 

Hawai'i is a state of the United States of America. To verify if you need a visa to enter the U.S.A., you can use the Visa Wizard. More information can be found on the U.S. Department of State page. For more details about how to apply your visa, please contact your local U.S.A. Consulate or Embassy. 

If you need an invitation letter for your visa, please send your request to vvv10@gemini.edu.

Social events

Welcome cocktail: A registration booth will be set Sunday at 5pm next to the bar at the Hilo Hawaiian Hotel.

Conference dinner: There will be a conference dinner on Tuesday at 6pm at the 'Imiloa Center (walking distance from Gemini). There is no additional charge for those attending the dinner.

Summit tour: Due to unforseen events, the summit tour on 22 Aug has been cancelled.
