Could a college merger close the transatlantic gap?

Yeast mating: Getting close to membrane merger

The machinery that mediates membrane fusion during yeast mating has remained elusive. But now a post-genomics approach has provided a powerful wedge into this difficult problem: a pheromone-induced multimembrane spanning protein has been identified as a key part of the mating machine.

The Relative Stability Against Merger of Close , Compact Binaries

The orbital separation of compact binary stars will shrink with time due to the emission of gravitational radiation. This inspiralling phase of a binary system’s evolution generally will be very long compared to the system’s orbital period, but the final coalescence may be dynamical and driven to a large degree by hydrodynamic effects, particularly if there is a critical separation at which the...

2MASS/SDSS Close Major-Merger Galaxy Pairs: Luminosity Functions and Merger Mass Dependence

We select a close “major-merger candidate” galaxy pair sample in order to calculate the Ks luminosity function (LF) and pair fraction representative of the merger/interaction component of galaxy evolution in the local universe. The pair sample (projected separation 5 h kpc ≤ r ≤ 20 h kpc, Ks-band magnitude difference ∆Ks ≤ 1 mag) is selected by combining the Two Micron All Sky Survey (2MASS) wi...

NIR Luminosity Function of Galaxies in Close Major-Merger Pairs and Mass Dependence of Merger Rate

A sample of close major-merger pairs (projected separation 5 ≤ r ≤ 20h kpc, Ks band magnitude difference δKs ≤ 1 mag) is selected from the matched 2MASS-2dFGRS catalog of Cole et al. (2001). The pair primaries are brighter than Ks = 12.5 mag. After corrections for various biases, the comparison between counts in the paired galaxy sample and counts in the parent sample shows that for the local ‘...
