VLT 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 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 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 ...
متن کاملKeck spectroscopy of globular clusters in the spiral galaxy NGC 2683
We analyse Keck spectra of 24 candidate globular clusters (GCs) associated with the spiral galaxy NGC 2683. We identify 19 bona fide GCs based on their recession velocities, of which 15 were suitable for stellar population analysis. Age and metallicity determinations reveal old ages in 14 out of 15 GCs. These old GCs exhibit age and metallicity distributions similar to that of the Milky Way GC ...
متن کاملSpectroscopy of globular clusters in the low - luminosity spiral galaxy NGC 45 ⋆
Context. Extragalactic globular clusters have been studied in elliptical galaxies and in a few luminous spiral galaxies, but little is known about globular clusters in low-luminosity spirals. Aims. Past observations with the ACS have shown that NGC 45 hosts a large population of globular clusters (19), as well as several young star clusters. In this work we aim to confirm the bona fide globular...
