The nearby early-type galaxy NGC4261 reveals strikingly asymmetric distributions of X-ray sources as seen with Chandra, and globular clusters (GC) as seen in the optical band. To address the link between these populations based on their spatial correlation, luminosity function and spectral properties, and to inve- stigate the possibility that this effect is due to the galaxy's merger history, we propose a 100ksec Chandra ACIS-S3 exposure, which will detect X-ray sources down to typical LMXB luminosities (Lx~5E37 erg/s), and HST-WFPC2 observations to obtain a deep census of the GC population over the whole galaxy. These data will also allow a detailed study of its complex gaseous component, and provide information on the unique two-sided X-ray jet.

The goal of this program is the study of the globular cluster population in the nearby elliptical galaxy NGC4261. In order to cover the D25 area of the galaxy we observe 6 fields with a 2-point dither pattern. In order to ensure uniform coverage we request for the observations to be performed with the same orientation (as was specified in the proposal). The selected orientation gives the maximum visibility during the observing period. Instead of definining new targets we apply POS-TARG offsets with respect to the nucleus of the galaxy. The exposure in each position is 800sec for each of the F450W, F606W and F814W filters.
