Abstract

We present here the preliminary observations of the merging galaxy cluster Abell 3376 using the Murchison Widefield Array (MWA). Data from the commissioning phase (32 tiles) in the Beta and Gamma configuration is used. Observations were carried out at three frequencies: 118, 150 and 178 MHz. All three images clearly detect the well-known east and west relics in the periphery of the cluster. The spectral indices of the relics in the frequency range 100 – 1400 MHz were estimated to be –1.440.15 and –1.330.1, respectively. However, no central radio halo was detected. We plan to analyze the full 128 tile observations of the cluster which are expected to be ten times more sensitive than the current observations.
