Characterizing bar structures : application to NGC 1300 , NGC 7479 and NGC 7723
Detailed surface photometry has been carried out for three barred galaxies with use of high resolution CCD broadband images in the B, V and I bands. Using azimuthal luminosity profiles and their decomposition into Fourier Series, the structural parameters (length and strength) of the bars in the three galaxies have been obtained. We have also inferred the corotation radii (CR) using information...
متن کاملPhotometric Observations of the Galactic Globular Clusters NGC 1904 and NGC 6341
We present multi-colour broad band CCD photometric observations of a few thousands of stars located region of the galactic globular clusters NGC 1904 and NGC 6341. These observations are used to generate their deep colour magnitude diagrams (CMDs) to study overall morphologies of sub giant, red giant, asymptotic giant and horizontal branches. We also determine the main sequence morphology of th...
متن کاملPhotometric and kinematic studies of open star clusters III . NGC 4103 , NGC 5281 , and NGC 4755 ⋆ , ⋆ ⋆
We present CCD photometry and proper motion studies of the three open star clusters NGC4103, NGC5281, and NGC4755 (κ Cru). By fitting isochrones to the colour magnitude diagrams, we found that all three objects are young open star clusters with ages of at most t = 45 Myr. They are located at distances from approx. 1600 pc to 2200 pc, derived from distance moduli (m−M)0 ranging from 11 mag to 12...
متن کاملThe star - burst galaxies NGC 278 , NGC 660 , NGC 3628 , NGC 4631 , and NGC 4666
Aims. We study the physical properties and mass of molecular gas in the central regions of galaxies with active nuclei. GHz [CI] maps in three of these are used to model the molecular gas. Results. All five objects contain bright CO emission in the central regions. Clear central concentrations were found in NGC 660, NGC 3628, and NGC 4666, but not in the weakest CO emitters NGC 278 and NGC 4631...
متن کاملObservations of Ngc 5548
We present simultaneous observations by EUV E, ASCA, and RXT E of the type 1 Seyfert galaxy NGC 5548. These data indicate that variations in the EUV emission (at D0.2 keV) appear to lead similar modulations in higher energy keV) X-rays by D10È30 ks. This is contrary to popular (Z1 models which attribute the correlated variability of the EUV, UV and optical emission in type 1 Seyferts to reproce...
