2nd VVV Science Meeting, Univ. of Hertfordshire

July 19, 2011

This meeting aims to bring together researchers involved in the wide field optical and near infrared surveys of the Galactic plane in the northern and southern hemispheres. The main surveys are:

UVEX/IPHAS     (u,g,r,i,Halpha northern plane)
VPHAS+             (u,g,r,i,Halpha southern plane)
UKIDSS GPS     (JHK northern plane)
VISTA VVV       (ZYJHKs bulge and southern plane, with ~80 epochs at Ks.)

There will also be discussion of results from “companion” surveys UWISH2 2.12 micron H2 survey and GLIMPSE360.


The Monday to Wednesday sessions will have more emphasis on the IR surveys, while Thursday and Friday it will shift more towards the optical surveys.

All sessions will be in the lecture theatre LC108, apart from the last which will be held in D102 (a classroom not far away).

SOCIAL EVENTS: We are arranging the opportunity for a pub evening meal on Tuesday 19th. The cost of eating/drinking is up to you, according to your need – typical mains are in the region of 8-10 pounds, and drinks will be at normal pub prices. Transport to/from the pub is being set up. Also a dinner for Thursday evening, 21st, has been booked at one of the better restaurants in St Albans (an easily-reached market town with abbey and roman ruins, a few miles from Hatfield), for which the price to be paid on the night will be 20.00 pounds + 2.50 service. This will cover choice of food from their menu B. Soft drinks, tea/coffee to finish, and some initially laid-on wine (and a per head food subsidy) will be taken care of by us. We ask you to sign up for these and, in the case of the pub, ask you to indicate a menu preference by the morning of the 19th, so that we might confirm numbers. The Darcy’s list will close on Wednesday.
