Globular 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 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 ...
متن کاملYoung star clusters: Progenitors of globular clusters!?
Star cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. Young clusters are observed to form in a variety of such galaxies, a substantial number resembling the progenitors of globular clusters in mass and size, but with significantly enhanced metallicity. From studies of the metal-poor and metal-rich star cluster populati...

The approximate limiting magnitudes for direct plates are quoted in the table. They depend on the seeing; the numbers given are for medium seeing and deeper plates are obtained under excellent conditions. These values may possibly be furt...
متن کاملKeck Spectroscopy of Two Young Globular Clusters in the Merger Remnant Ngc 3921
Low-resolution, ultraviolet-to-visual spectra of two candidate globular clusters in the merger remnant NGC 3921 (cz LG = 6021 km s−1) are presented. These two clusters of apparent magnitude V ≈ 22.2 (MV ≈ −12.5) lie at projected distances of about 5 kpc (0.9Reff ) from the center and move with halo-type radial velocities relative to the local galaxy background. Their spectra show strong Balmer ...
