Crossroads in Studies of Galaxy Evolution

Cross-Roads in Studies of Galaxy Evolution

Studies of galaxy evolution at optical and near-infrared wavelengths have reached an interesting point in their historical development and the arrival of a new millenium provides an appropriate occasion to review the overall direction in which this subject is moving. The aim of this short essay is to emphasize the qualitatively different datasets now arriving and the more detailed and challengi...

Messier’s renown in comet spotting had inspired the furry moniker from King Louis XV, but o...

Galaxy Evolution with Alma

The submillimeter and millimeter domains are privileged for the exploration of galaxies at high redshift, because of the negative K-correction: the peak of the dust emission at 60-100 microns is red-shifted in these domains. Already blind surveys in blank fields with today instrumentation have discovered in the continuum of the order of one object per square arcmin, with large limitations due t...
