The Globular Cluster System of NGC 5846 Revisited : Colours , Sizes and X - Ray Counterparts ⋆
NGC5846 is a giant elliptical galaxy with a previously well studied globular cluster system (GCS), known to have a bimodal colour distribution with a remarkably high red fraction. Here we revisit the central galaxy regions searching for new globular cluster (GC) candidates, and measuring, magnitudes, colours and sizes for them. We also search for their X-ray counterparts. We use archival Hubble...
متن کاملX-ray Halo Around the Spiral Galaxy NGC 4631 Observed with Suzaku
Suzaku observation of the edge-on spiral galaxy NGC 4631 confirmed its X-ray halo extending out to about 10 kpc from the galactic disk. The XIS spectra yielded the temperature and metal abundance for the disk and the halo regions. The observed abundance pattern for O, Ne, Mg, Si and Fe is consistent with the metal yield from type II supernovae, with an O mass of about 10M⊙ contained in the halo...
متن کاملOn the peculiar red clump morphology in the open clusters NGC 752 and NGC 7789
The red clump stars in the open cluster NGC 752 present a peculiar distribution in the colour-magnitude diagram (CMD): the clump is observed to present a faint extension, slightly to the blue of the main concentration of clump stars. We point out that a similar structure is present in the CMD of NGC 7789, and discuss their possible origins. This feature may be understood as the result of having...
متن کاملX-ray Emission, Optical Nebulosity and Dust in Early-type Galaxies. I. the Dusty Nebular Filaments in Ngc 5846
We present new optical imagery of the X-ray bright elliptical galaxy NGC 5846, the dominant galaxy of a small group of galaxies. A filamentary dust lane with a dust mass of ∼ 7 10 M⊙ is detected in the central few kpc of NGC 5846. The optical extinction properties of the dust features are consistent with those of dust in our Galaxy. The morphology of the dust features are strikingly similar to ...
