SCUBA Observations of NGC 1275
Deep SCUBA observations of NGC 1275 at 450μm and 850μm along with the application of deconvolution algorithms have permitted us to separate the strong core emission in this galaxy from the fainter extended emission around it. The core has a steep spectral index and is likely due primarily to the AGN. The faint emission has a positive spectral index and is clearly due to extended dust in a patch...
متن کاملNear infrared imaging spectroscopy of NGC 1275
We present H and K band imaging spectroscopy of the core regions of the cD/AGN galaxy NGC1275. The spectra, including lines from H2, H, CO bandheads, [Fe ii], and [Fe iii], are exploited to constrain the star formation and excitation mechanisms in the galaxy’s nucleus. The near-infrared properties can largely be accounted for by ionized gas in the NLR, dense molecular gas, and hot dust concentr...
متن کاملObservations of CO in the eastern filaments of NGC 1275
We recently found extended CO(2–1) emission from cold molecular gas embedded in the network of Hα filaments surrounding the galaxy NGC 1275 (Salome et al. 2006). We now present CO(2–1) interferometer maps of the eastern filaments, at high spatial and spectral resolutions. The cold molecular gas is detected by the Plateau de Bure Interferometer along the eastern filaments over an extent of 15′′,...
متن کاملMolecular Gas in the Perseus Cooling Flow Galaxy , NGC 1275
The central arcminute of the Perseus cooling flow galaxy, NGC 1275, has been mapped with the JCMT in CO(2–1) at 21 resolution, with detections out to at least 36 (12 kpc). Within the limits of the resolution and coverage, the distribution of gas appears to be roughly E-W, consistent with previous observations of CO, X-ray, Hα, and dust emission. The total detected molecular hydrogen mass is ∼ 1...
متن کاملOn the Nature of the NGC 1275 System
Sub-arcsecond images, taken in B, R, and Hα filters, and area spectroscopy obtained with the WIYN 3.5-m telescope provide the basis for an investigation of the unusual structures in the stellar body and ionized gas in and around the Perseus cluster central galaxy, NGC 1275. Our Hα filter is tuned to gas at the velocity of NGC 1275, revealing complex, probably unresolved, small-scale features in...
