Symposium S4
3 – 4 July 2014
Origin of Cosmic Dust
News:
The program is now available.
Aims and scope
The goal of the meeting is to present a comprehensive assessment of cosmic dust in all astrophysical environments where dust is important for the physical and chemical processes. Cosmic dust plays a huge role in the appearance of the universe, reprocessing fully half of all non-primordial radiation, fundamentally altering our view of nearly every cosmic phenomenon. Dust is vital to the formation of planets and molecules and plays a fundamental role in nearly all star-formation. Yet its properties and it origin are still poorly understood. We do not understand the properties of dust in extinction or emission, though we are making rapid progress. However, it is not fully explained how large dust masses in the early universe are formed, whether through cool stars, supernovae or the interstellar medium. Here we bring together experts on gamma-ray bursts, supernovae, and AGB stars, in particular observers of dust, together with theorists of dust formation and evolution and experts on the local and early universe to examine all aspects of the formation of dust and its evolution.
The symposium will consist of three sessions focusing on different aspects of cosmic dust origin:
1. What is cosmic dust made of?
2. Where is dust formed?
3. The identities of the unidentified ISM features.
Our goal for the three sessions is to present the most important open questions in cosmic dust studies and discuss them thoroughly. We will have review talks which provide an overview of our understanding of the topic as a means to prime and facilitate these discussions. The review speakers will therefore have a strong focus on open questions. The invited speakers will explore the implications of their work on the subject of the relevant session with an impartial focus on open and controversial questions related to their work. We hope that during the meeting many new synergistic ideas will emerge.
