Abstract (from CDS):

We present a determination of the Hubble constant and central electron density in the cluster Abell 1835 (z=0.2523) from measurements of X-ray emission and millimeter-wave observations of the Sunyaev-Zeldovich (S-Z) effect with the Sunyaev-Zeldovich Infrared Experiment (SuZIE) multifrequency array receiver. Abell 1835 is a well studied cluster in the X-ray with a large central cooling flow. Using a combination of data from ROSAT PSPC and HRI images and millimeter wave measurements we fit a King model to the emission from the ionized gas around Abell 1835 with θ₀=0'.22±0'.02 and β=0.58±0.02. Assuming the cluster gas to be isothermal with a temperature of 9.8^+2.3_–1.3 keV, we find a y-parameter of 4.9±0.6x10^–4 and a peculiar velocity of 500±1000 km.s^–1 from measurements at three frequencies, 145, 221, and 279 GHz. Combining the S-Z measurements with X-ray data, we determine a value for the Hubble constant of H₀=59⁺³⁸_–28 km.s^–1.Mpc^–1 and a central electron density for Abell 1835 of n_e0=5.64^+1.61_–1.02x10^–2 cm^–3 assuming a standard cosmology with Ω_m=1 and Ω_Λ=0. The error in the determination of the Hubble constant is dominated by the uncertainty in the temperature of the X-ray emitting cluster gas.
