  journal={The Astrophysical Journal},
Using the Owens Valley Radio Observatory (OVRO) Millimeter-Wavelength Array, 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 of both its previous CO detection with the IRAM 30 m telescope and its classification as a Malin 1 "cousin;" an LSB galaxy with M ≥ 1010 M☉. The OVRO map detected approximately 65% of the CO (1-0) flux found earlier with the single-dish measurements, giving a detected gas… Expand

Properties of Molecular Gas in Massive Low Surface Brightness Galaxies, Including New 12 CO Observations of Three Malin 1 ``Cousins''
To date, the only low surface brightness (LSB) galaxies that have been detected in CO are the massive LSB (MLSB) galaxies. In 2003, O'Neil, Schinnerer, & Hofner hypothesized that it is the prominentExpand

Active galactic nucleus activity and black hole masses in low surface brightness galaxies
We present medium resolution optical spectroscopy of a sample of nine low surface brightness (LSB) galaxies. For those that show clear signatures of active galactic nucleus (AGN) emission, we haveExpand
Fundamental Properties of the Dark and the Luminous Matter from the Low Surface Brightness Discs
Dark matter (DM) is one of the biggest mystery in the Universe. In this review, we start reporting the evidences for this elusive component and discussing about the proposed particle candidates andExpand
Giant Low Surface Brightness Galaxies: Evolution in Isolation
Giant Low Surface Brightness (GLSB) galaxies are amongst the most massive spiral galaxies that we know of in our Universe. Although they fall in the class of late type spiral galaxies, theirExpand


First Detection of CO in a Low Surface Brightness Galaxy
We report on the first attempts at searching for CO in red low surface brightness galaxies, and the first detection of molecular gas in a low surface brightness [μB(0)obs > 23 mag arcsec-2] galaxy.Expand
Low surface brightness (LSB) galaxies are galaxies dominated by an exponential disc whose central surface brightness is much fainter than the value of mu(B)(0) = 21.65 +/- 0.30 mag arcsec(-2) foundExpand
