Evidence for Redshift Periodicity in Nearby Field Galaxies - Guthrie, Napier () Citation Context ...the expected values assuming that this explanation is correct, they conclude that the observed effect of quasar redshift discretization is caused by observational selection.

We use redshift determinations and spectral analysis of galaxies in the 2dF Galaxy Redshift Survey to study the properties of local radio sources with S≥1 mJy. 557 objects (hereafter called the spectroscopic sample) drawn from the FIRST survey, corresponding to 2.3 per cent of the total radio...
A large cloud of molecular gas detected through 12CO is located at the end of one optical tail non thermal radio continuum region ([28], [29]); (ii) the exceptional detection of the molecule H2in from interacting pairs of galaxies: interactions in pairs trigger an inflow of gas to the ...
It has not yet been demonstrated by the new surveys that HI-rich LSB galaxies are not properly represented in this catalog of nearby galaxies. Although new optical surveys are discovering heretofore uncatalogued galaxies at greater distances than the depth of the FT Catalog, they do not alter ...
Galaxies: Clusters: GeneralCosmology: Large-Scale Structure of UniverseWe use the two-point correlation function in redshift space, $\\xi(s)$, to study the clustering of the galaxies and groups of the Nearby Optical Galaxy (NOG) sample, which is a nearly all-sky, complete, magnitude-...

Observations of the interstellar medium are key to deciphering the physical processes regulating star formation in galaxies. However, observational uncertainties and detection limits can bias the interpretation unless carefully modeled. Here I re-analyze
<italic>Context.</italic> Galaxies in the local Universe are thought to require ongoing replenishment of their gas reservoir in order to maintain the observed star formation rates. Cosmological simulations predict that this accretion can occur in both a
