Sunyaev-Zel'dovich studies of clusters of galaxies using the ACBAR instrument on the viper telescope at the South Pole


After 10 years working in the United States, Dr Kathy Romer has recently (January 1st 2004) taken up a permanent (lectureship) position at the University of Sussex. We request funds to aid Dr Romer with her European re-integration and specifically to conti nue to play an active role in the US based ACBAR project. This in turn will allow Dr Romer to transfer to Europe the knowledge she has acquired during her time in the USA in the field of Sunyaev-Zel'dovich Effect (SZE) studies of clusters of galaxies. It w ill also foster continued and lasting co-operation with her ACBAR collaborators and with the broader SZE community in the US and Europe. Romer has been leading the multi-wavelength analysis of clusters observed with the ACBAR instrument on the Viper Telesc ope at the South Pole. ACBAR (, a sixteen pixel bolometer detector, has been operating on Viper since January 2001 and is able to survey the microwave sky simultaneously at three frequencies that span the 220 GHz ``null'' in the thermal Sunya ev-Zel'dovich (SZ) spectrum. With an IRG award, Romer will be able to continue her involvement with this unique, high profile, project. Her science goals for ACBARSZ involve the successful completion of two complementary ACBAR cluster surveys; The Viper S unyaev-Zel'dovich Survey and The ACBAR Blind Sunyaev-Zel'dovich Cluster Survey. The bulk of the funds will be used to hire two outstanding young researchers (Turkish postdoc and a Finnish Graduate Student, both are women). They will aid Romer in the analy sis, publication and dissemination of ACBAR observations/results. The ACBARSZ team at Sussex will form the core of Romer¿s ambition to develop a world class research group at Sussex. In addition, we request travel funds to allow the Sussex ACBARSZ team to meet with collaborators in the USA, and to present ACBARSZ results at international conferences, small specialized workshops and at invited seminars/colloquia.
