3rd DENIS Euroconference on

The Impact of Large-Scale Near-IR Sky Surveys

24-26 April 1996

Puerto de la Cruz, Tenerife, Spain


Scientific Programme

DENIS (Deep European Near Infrared Southern Sky Survey), a project aimed at mapping the full southern sky at two IR bands (J and K) plus one optical (I) has already started its routine operational phase in the ESO 1m telescope at La Silla (Chile). This is the first large scale NIR survey, whose results are expected to produce a major impact in many areas of modern Astronomy, by themselves alone or in conjunction with other large scale surveys at different wavelengths.

The 3rd DENIS Euroconference, funded by the European Union as part of its Human Capital and Mobility programme, will present the first scientific results obtained by DENIS. In addition, other major large scale surveys, like 2MASS, ISO survey projects, COSMOS and TMGS, will discussed. Hence, the goal of this meeting is to focus on the use of large area NIR surveys in basic astrophysical research. Special attention will be given to DENIS and to point out the specific problems that can only be probed with such surveys.

The 3 days meeting is formatted into 6 half day sessions, each of one will be devoted to the following topics:

The new Near Infrared surveys and other related surveys (2MASS, ISO, TMGS, ... ).

Galactic Structure, including presentations on AGB stars.

Star formation regions and young objects.

Image processing and data dissemination.

Extragalactic Astrophysics.

Pannel discussion and concluding remarks.

In each of sessions 2 to 5 the DENIS first scientific results in the specific field will be presented. In addition, an invited review about the use and potential of large surveys for each of the above topics will be given.

The conference will be organized in invited talks, a limited number of contributed oral presentation and a more general poster session(s).

List of confirmed invited speakers:

Eduardo Battaner

Andrea Moneti

Ulrich Klass

Martin Cohen

Steve Price

Ralph Neuhaeuser

Eduardo Martin

Steven Schneider

Plus several talks given by DENIS members
