High-latitude H I in the Low Surface Brightness Galaxy Ugc 7321
From the analysis of sensitive H i 21-cm line observations, we find evidence for vertically extended H i emission (|z| <∼2.4 kpc) in the edge-on, low surface brightness spiral galaxy UGC 7321. Three-dimensional modelling suggests that the H i disk of UGC 7321 is both warped and flared, but that neither effect can fully reproduce the spatial distribution and kinematics of the highest z-height ga...
متن کاملThe First Co Map of a Low Surface Brightness Galaxy
Using the Owens Valley Radio Observatory Millimeter-Wavelength Array (OVRO) we have obtained the first CO map of a low surface brightness (LSB) galaxy. The studied galaxy, UGC 01922, was chosen for these observations because both of its previous CO detection with the IRAM 30m telescope and its classification as a Malin 1 ‘cousin’ – an LSB galaxy with MHI ≥ 10 10 M⊙. The OVRO map detected approx...
متن کاملA search for Low Surface Brightness galaxies in the near-infrared I. Selection of the sample
A sample of about 3,800 Low Surface Brightness (LSB) galaxies was selected using the all-sky nearinfrared (J , H and Ks-band) 2MASS survey. The selected objects have a mean central surface brightness within a 5′′ radius around their centre fainter than 18 mag arcsec in the Ks band, making them the lowest surface brightness galaxies detected by 2MASS. A description is given of the relevant prope...
متن کاملNearby Gas-Rich Low Surface Brightness Galaxies
We examine the Fisher–Tully cz < 1000 km s galaxy sample to determine whether it is a complete and representative sample of all galaxy types, including low surface brightness populations, as has been recently claimed. We find that the sample is progressively more incomplete for galaxies with (1) smaller physical diameters at a fixed isophote and (2) lower HI masses. This is likely to lead to a ...
متن کاملCo Detections of Edge-on Low Surface Brightness Galaxies
We have obtained deep CO(1-0) observations of 8 nearby, edge-on, low surface brightness (LSB) spiral galaxies using the NRAO 12-m telescope. We report detections of 3 of our targets at > 4σ level as well as one marginal (∼ 3σ) detection. These are among the first direct detections of molecular gas in late-type, LSB spirals. Using a Galactic CO-to-H2 conversion factor, we derive MH2 ∼ 1.4 − 3.5 ...
