Ram pressure stripping of disk galaxies in galaxy clusters
While galaxies move through the intracluster medium of their host cluster, they experience a ram pressure which removes at least a significant part of their interstellar medium. This ram pressure stripping appears to be especially important for spiral galaxies: this scenario is a good candidate to explain the differences observed between cluster spirals in the nearby universe and their field co...
متن کاملRam pressure stripping of the multiphase ISM in the Virgo cluster spiral galaxy NGC 4438
Ram pressure stripping of the multiphase ISM is studied in the perturbed Virgo cluster spiral galaxy NGC 4438. This galaxy underwent a tidal interaction ∼ 100 Myr ago and is now strongly affected by ram pressure stripping. Deep VLA radio continuum observations at 6 and 20 cm are presented. We detect prominent extraplanar emission to the west of the galactic center, which extends twice as far as...
متن کاملThe consequences of ram pressure stripping on the Virgo cluster spiral galaxy NGC 4522
New Hα Fabry-Perot interferometer observations of the Virgo cluster spiral galaxy NGC 4522 are presented. A velocity field up to a radius of 60 was obtained. The observed rotation curve is symmetric. It is not perturbed in the inner disk. For radii > 50 it shows a solid body rotation. We compare these data with a numerical model which includes the effects of ram pressure stripping. The model ca...
متن کامل4 Ram Pressure Stripping in the Low Luminosity Virgo Cluster Elliptical Galaxy NGC 4476
We present a deep VLA search for HI emission from the low-luminosity Virgo Cluster elliptical galaxy NGC 4476, which contains 1.1×10 8 M ⊙ of molecular gas in an undisturbed disk in regular rotation. No HI was detected. The rms noise in the final image corresponds to a 3σ column density sensitivity of 1.2×10 20 cm −2 at the position of NGC 4476, averaged over the 4 kpc beam. The total HI mass i...
متن کاملGalactic-scale Outtow and Supersonic Ram-pressure Stripping in the Virgo Cluster Galaxy Ngc 4388
The Hawaii Imaging Fabry-Perot Interferometer (HIFI) on the University of Hawaii 2.2m telescope was used to map the H and O III] 5007 emission-line prooles across the entire disk of the edge-on Sb galaxy NGC 4388, with resolution 40 { 60 km s ?1 and arcsecond sampling. This galaxy is projected only 300 kpc from the center of the Virgo cluster and is moving at 1,500 km s ?1 relative to the clust...
