First Stars and Galaxies: Challenges in the Next Decade

Conference Program

All talks and posters will be in the AT&T Conference Center. Lunch will be provided daily by the AT&T Center and is included in the registration fee. The conference reception will be held Monday evening at the Texas Advanced Computing Center (TACC), and transportation to and from the Center will be provided. In addition, there will be a barbeque in downtown Austin on Tuesday evening. On Wednesday evening the conference dinner will be held at the Driskill Hotel (travel arrangements to be determined) and we are pleased to announce that Professor Steven Weinberg, Nobel Laureate in Physics, will be our dinner speaker. There is an additional $50.00 fee to attend this dinner, which is payable at the time of registration. Coffee and snacks will be provided during breaks.

Meeting format: Each morning and afternoon session will be dedicated to one of five challenges:

  • Challenges I: The Primordial IMF

  • Challenges II: The First Supernovae

  • Challenges III: The Pop III - II Transition

  • Challenges IV: Hunting for the First Galaxies

  • Challenges V: Early Black Holes and the SMBH Assembly Process

Each challenge will be opened by one or more "review" talks to be followed by both "invited" and "contributed" talks. The lengths of the talks are

  • review (R) 45 min: 35 min talk / 10 min discussion

  • invited (I) 25 min: 20 min talk / 5 min discussion

  • contributed (C) 15 min: 12 min talk / 3 min discussion

PDF or powerpoint versions of all talks will be posted after they are presented.

Poster information: There will be a dedicated hour each day from 1:30 - 2:30 pm for the viewing and discussion of posters. We strongly encourage presenters to be available for questions in front of their poster that hour if they are not attending a Working Group. Many very interesting new results will appear in these posters that would have been accepted as talks had there been more room in the program, so we invite all to view and discuss them.

Posters can be set up in the Center on Monday morning or later. There are no strict size or format guidelines for the posters; AAS or IAUS rules can be taken as good guidelines. They must be taken down by 2:30 p.m. on Thursday. Participants will be asked to provide a PDF or PS version of their poster as well as a one-page summary for inclusion in the conference proceedings.

Working Groups: To foster interaction between theorists and leading high-redshift observers, and to establish simulation roadmaps for the next few years, a working group will be organized each day for a specific challenge over the second half of the lunch hour. Prior to the conference, an email discussion will be organized among the speakers in a given challenge to solicit a list of the most important issues that should be investigated by upcoming numerical models (those not in an email list can be added to it by contacting Dan Whalen). The questions will be presented at the beginning of each working group, which will be presided over by two chairmen. These chairmen will then moderate the ensuing discussion, ensuring that all can give input in a discussion format that is more structured than a free-for-all but less rigid than a talk or panel.
