2015 VLTI Community Days

2nd VLTI Community Days, Tenerife, Canary Islands, 22nd-26th June 2015 (EWASS 2015)

The VLTI Community Day (VCD) provides a platform for the VLTI user community to exchange with ESO, to discuss about ongoing and future projects, and to advertise the scientific opportunities offered by VLTI to the wider astronomical community.

An important objective of the VCD is also to serve as entrance point for potential new VLTI users. For this purpose, we will review the science opportunities enabled by VLTI, set them into relation to the capabilities of other techniques and facilities (e.g. ALMA), and outline available tools and contact points for user support. In fact, several initiatives are currently underway in order to make VLTI more accessible to non-expert users, including the establishment of VLTI expertise centres.

With the 2nd-generation VLTI instruments nearing completion, we will also facilitate a discussion about the future of VLTI in the ELT era. Studies in this direction are currently conducted by several groups, investigating infrastructure enhancements that could push VLTI either towards imaging at higher fidelity, higher contrast, or at new wavelength regimes. The meeting will provide the stage to outline these plans and to collect community feedback. This feedback will be incorporated into the whitebook that is currently prepared by the OPTICON-funded "Future of Interferometry in Europe" working group, providing input for upcoming infrastructure decisions.

The meeting comprises three sessions (1.5 hours each) and will be open to contributed talks, where we will favour contributions that present recent highlights in high-angular resolution research, on innovative uses of interferometry, or instrumentation aspects. We welcome poster contributions about all topics related to high-angular resolution astronomy.
