NGC 4254 : a spiral galaxy entering the Virgo cluster
Deep Effelsberg Hi spectra of the one-armed, bright Virgo cluster spiral galaxy NGC 4254 are presented. Five different positions were observed in the 21 cm Hi line with the Effelsberg 100-m telescope: one in the center and 4 located one HPBW to the NE, NW, SW, and SE, respectively, from the galaxy center. The spectra are compared to existing deep VLA observations, and the single dish and interf...
متن کاملA Local Group Polar Ring Galaxy : NGC 6822
Star counts, obtained from a 2 × 2 degree area centered on NGC 6822 have revealed an optical image of this galaxy composed of two components: in addition to the well-known HI disk with its young stellar component, there is a spheroidal stellar structure as extensive as its HI disk but with its major axis at roughly right angles to it which we traced to at least 9 scale lengths. Radial velocitie...
متن کاملA dynamical model for the heavily ram pressure stripped Virgo spiral galaxy NGC 4522
Context. Evolution of spiral galaxies in the Virgo cluster. Aims. We determined the parameters of the interaction between the interstellar medium of NGC 4522 and the intracluster medium of the Virgo cluster. Methods. A dynamical model including ram pressure stripping is applied to the strongly Hi deficient Virgo spiral galaxy NGC 4522. A carefully chosen model snapshot is compared with existing...
متن کاملPhotometric Survey of the Polar Ring Galaxy Ngc 6822
We have previously established, from a carbon star survey, that the Local Group dwarf irregular galaxy NGC 6822 is much larger than its central bright core.
متن کاملExtended Red Emission in the “ Evil Eye ” Galaxy ( NGC 4826 )
NGC4826 (M64) is a nearby Sab galaxy with an outstanding, absorbing dust lane (called the " Evil Eye ") asymmetrically placed across its prominent bulge. In addition, its central region is associated with several regions of ongoing star formation activity. We obtained accurate low-resolution (4.3 ˚ A/pixel) long-slit spectroscopy (KPNO 4-Meter) of NGC4826 in the 5300 – 9100Å spectral range, wit...
