Segregation and Tidal Tails of the Globular Cluster NGC 7492
We present a wide field CCD photometric study of Galactic globular cluster NGC 7492. The derived V R color-magnitude diagram extends down to about 3.5 mag below the cluster main sequence turn-off. The field covers 42 × 42 about 3 times larger than the known tidal radius of this cluster. The sample of cluster member candidates obtained by CMD-mask process has been used to construct luminosity an...
متن کاملThe Mass Function of NGC 288
We present NICMOS NIC3 observations of the Galactic globular cluster NGC288, taken South East at 2.4 times the cluster’s half-light radius in the J and H bands. We have detected the cluster main sequence down to J ≃ 25 and H ≃ 24. The corresponding luminosity function covers the range 3 < MH < 9 and peaks at MH ≃ 6.8. The theoretical tracks of Baraffe et al. (1997) at [Fe/H ] = −1.3 give a mass...
متن کاملThe Discovery of Tidal Tails around the Globular Cluster Ngc 5466
We report the discovery of tidal tails around the high-latitude Galactic globular cluster NGC 5466 in Sloan Digital Sky Survey (SDSS) data. Neural networks are used to reconstruct the probability distribution of cluster stars in u, g, r, i, z space. The tails are clearly visible, once extra-galactic contaminants and field stars have been eliminated. They extend ∼ 4 • on the sky, corresponding t...
متن کاملUv Morphology and Star Formation in the Tidal Tails of Ngc 4038/39
We present GALEX FUV (1530 Å) and NUV (2310 Å) observations of the archetypal merging system NGC 4038/39, “The Antennae”. Both tails are relatively bright in the UV , especially in the vicinity of the Tidal Dwarf Galaxy candidates at the end of the southern tail. The UV light generally falls within the optically delineated tails, although the UV light is considerably more structured, with a rem...
متن کاملConstraining Dark Halo Potentials with Tidal Tails
We present an extensive parameter survey to study the influence of halo mass profiles on the development of tidal tails in interacting disk galaxies. We model the galaxies using a fixed exponential disk with a central bulge and vary the halo potential over a range of parameters using both the Hernquist and NFW mass distributions, probing the effect of the halo mass, extent and concentration. We...
