HRI observations of the Local Group galaxies IC 10 , NGC 147 and NGC 185
We report on pointed X-ray observations of IC 10, NGC 147 and NGC 185 made with the ROSAT High Resolution Imager (HRI). These are three Local Group galaxies that have never been previously studied in detail in the X-ray regime. IC 10 is the closest starburst galaxy to our own Galaxy, and NGC 147 and NGC 185 are companions to M31. We have discovered a variable X-ray source coincident with IC 10....
متن کاملAges , metallicities , and [ α / Fe ] ratios of globular clusters in NGC 147 , NGC 185 , and NGC 205
We present measurements of ages, metallicities, and [α/Fe] ratios for 16 globular clusters (GC) in NGC 147, NGC 185, and NGC 205 and of the central regions of the diffuse galaxy light in NGC 185, and NGC 205. Our results are based on spectra obtained with the SCORPIO multi-slit spectrograph at the 6-m telescope of the Russian Academy of Sciences. We include in our analysis high-quality HST/WFPC...
متن کاملSurface Photometry of the Dwarf Elliptical Galaxies Ngc 185 and Ngc 205 1
We present BVRI CCD surface photometry for the central(6 0 .35 6 0 .35) regions of the dwarf elliptical galaxies NGC 185 and NGC 205 in the Local Group. Surface brightness prooles of NGC 185 (R < 225 00) and NGC 205 (R < 186 00) show excess components in the central regions. The colors of NGC 185 get bluer inward at R < 25 00 , while they remain constant at R 25 00. The colors of NGC 205 get bl...
متن کاملSurface Photometry of the Dwarf Elliptical Galaxies Ngc 185 and Ngc 205
We present BVRI CCD surface photometry for the central(6.35 × 6.35) regions of the dwarf elliptical galaxies NGC 185 and NGC 205 in the Local Group. Surface brightness profiles of NGC 185 (R < 225) and NGC 205 (R < 186) show excess components in the central regions. The colors of NGC 185 get bluer inward at R < 25, while they remain constant at R ≥ 25. The colors of NGC 205 get bluer inward at ...
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...
