Structural Parameters from Ground - based Observations of Newly Discovered Globular Clusters in NGC 5128
We have investigated a number of globular cluster candidates from a recent wide-field study by Harris et al. (2004a) of the giant elliptical galaxy NGC 5128. We used the Magellan I telescope + MagIC camera under excellent seeing conditions (0.3′′ −0.6′′) and obtained very high resolution images for a sample of 44 candidates. Of these, 15 appear to be bonafide globular clusters in NGC 5128 while...
متن کاملNewly Discovered Globular Clusters in the Outer Halo of M31
We present nine newly discovered globular clusters in the outer halo of M31, found by a semi-automated procedure from an INT Wide Field Camera survey of the region. The sample includes a candidate at the largest known projected galactocentric radius yet from M31.
متن کاملGlobular clusters in NGC 5128 ?
We used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to search for globular clusters in the inner regions of the nearby giant elliptical galaxy NGC 5128. This galaxy is believed to be the product of a merger between a large elliptical galaxy and a small late-type spiral between 160 and 500 Myr ago. We identified 21 globular cluster candidates and measured their core radii...
متن کاملAn updated survey of globular clusters in M 31 . II . Newly discovered bright and remote clusters
Aims. We present the first results of a large spectroscopic survey of candidate globular clusters located in the extreme outskirts of the nearby M31 galaxy. The survey is aimed at ascertaining the nature of the selected candidates to increase the sample of confirmed M31 clusters lying more that 2 • away from the center of the galaxy. Methods. We obtained low resolution spectra (λ/∆λ ≃ 800 − 130...
متن کاملVLT spectroscopy of NGC 3115 globular clusters ⋆
We present results derived from VLT–FORS2 spectra of 24 different globular clusters associated with the lenticular galaxy NGC3115. A subsample of 17 globular clusters have sufficiently high signal–to–noise to allow precision measurements of absorption line-strengths. Comparing these indices to new stellar population models by Thomas et al. we determine ages, metallicities and element abundance ...
