The complete submillimetre spectrum of NGC 891
Submillimetre maps of NGC 891 have been obtained with the PRONAOS balloonborne telescope and with the ISOPHOT instrument on board the ISO satellite. In this article, we also gather data from IRAS and SCUBA to present the complete submillimetre spectrum of this nearby edge-on spiral galaxy. We derive submillimetre emission profiles along the major axis. The modified blackbody fits, assuming a si...
متن کاملSubmillimetre maps of the edge - on galaxy NGC 891
Broadband continuum images of the edge-on galaxy NGC 891 at 850 µm and 450 µm are presented. These images are very similar to the 1300µm and CO line images. With respect to the 850µm continuum, CO is strongest in the socalled molecular ring', and weakest at the largest radii sampled. Inside the molecular ring, the CO/850µm ratio is somewhat less than in the ring, but higher than in the remainde...
متن کاملLopsided galaxies : the case of NGC 891
It has been known for a long time that a large fraction of disc galaxies are lopsided. We simulate three different mechanisms that can induce lopsidedness: flyby interactions, gas accretion from cosmological filaments and ram pressure from the intergalactic medium. Comparing the morphologies, HI spectrum, kinematics and m = 1 Fourier components, we find that all of these mechanisms can induce l...
متن کاملGlobular Cluster Candidates in NGC 891 1
We use deep images taken with the Advanced Camera for Surveys on board the Hubble Space Telescope of the disk galaxy NGC 891, to search for globular cluster candidates. This galaxy has long been considered to be a close analog in size and structure to the Milky Way and is nearly edge-on, facilitating studies of its halo population. These extraplanar ACS images, originally intended to study the ...
متن کاملExtraplanar Dust in the Edge - On Spiral NGC 891
We present high-resolution (0.6 ′′-0.65 ′′) optical broad-band images of the edge-on Sb galaxy NGC 891 obtained with the WIYN 3.5-m telescope. These BVR images reveal a complex network of hundreds of dust absorbing structures far from the mid-plane of the galaxy. The dust structures have a wide range of morphologies and are clearly visible to |z| ∼ < 1.5 kpc from the mid-plane. In this paper we...
