Surface 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 کاملVery cold dust in the peculiar dwarf elliptical galaxy NGC 205 ?
ISO observations of NGC 205 between 120 and 200 μm resolve the emission from 20–24 K cold dust. It is extended to about 7.′5×7.′5 with bright concentrations in a 1.′5 north-south elongated area, similar to the that seen in HI. Supplemented by IRAS and mm literature data, the photometry of the total galaxy and the central region is disentangled. It indicates the presence of very cold dust below ...
متن کاملThe Nuclear Disk in the Dwarf Elliptical Galaxy Ngc 4486a1
Many ellipticals contain nuclear disks of dust and gas. Some ellipticals contain nuclear disks of stars that are distinct from the rest of the galaxy. We show that the dwarf E2 galaxy NGC 4486A contains both – it is a “Rosetta stone" object that tells us how nuclear disks evolve. Its properties suggest that, as accreted gas dissipates and settles toward the center, it forms stars and builds a s...
