THE SLOAN SUMMIT ON MICROWAVE FOREGROUNDS

        November 14-15, 1998



        Dear Colleagues,

        As has become a biannual tradition, the Institute for Advanced Study (IAS) in Princeton will host a Cosmic Microwave Background (CMB) workshop this fall. As before, this workshop will be informal, focused and quite technical. It is designed to foster discussions and exchanges among the researchers in the field. We would particularly like to encourage the participation of foreign participants.

        This year's workshop will focus strictly on foregrounds, addressing questions such as those listed below. Please note that there will not be any general CMB talks.

          Galactic foregrounds: free-free, synchrotron, dust & new dust emission mechanisms.

          Extragalactic foregrounds: discrete sources & Sunyaev-Zel'dovich effect.

          Secondary anisotropies: Integrated Sachs-Wolfe effect, gravitational lensing, patchy reionization & Ostriker-Vishniac effect.

          Measurements and models of foregrounds: frequency dependence, l-dependence, latitude dependence, spectral index fluctuations, non-gaussianity & polarization.

          Methods for detecting and removing foregrounds.

          Experimental impact of foregrounds: satellite missions, balloons, ground based experiments & interferometers.

        Please let us know if you would like to attend this workshop by emailing max@ias.edu.


        Logistics:

          The meeting will begin on Saturday November 14 at 10am and end on Sunday at 5pm.

          We have reserved a block of rooms at the Palmer Inn near Princeton (3499 Route 1 South) at $70/night +6% tax, including breakfast. If you wish to make a reservation at this rate, you must call 1-800-688-0500 by October 13. There is a free shuttle bus from the Palmer Inn to the IAS, so you will not need to rent a car.

          A more Princetonian option is the old Nassau Inn on Palmer Square, right in the heart of town, where $120 rooms can be reserved at (609) 921-7500.

          It is reasonably convenient to fly into Newark airport and drive (1 hour) or take the Princeton Airporter (1-800-468-6696, (609) 587-6600; $21 each way). The Airporter makes stops both at the hotels and the IAS. Another option is taking a train to Princeton Junction.


        Registration Fee:

          Thanks to the generosity of the Sloan Foundation, there will be no registration fee.
