We present an automated morphological classification in 4 types (E, S0, Sab, Scd) of ˜ 700,000 galaxies from the SDSS DR7 spectroscopic sample based on support vector machines. The main new property of the classification is that we associate a probability to each galaxy of being in the four morphological classes instead of assigning a single class

We report the detection of ADFS-27, a dusty, starbursting major merger at a redshift of z = 5.655, using the Atacama Large Millimeter/submillimeter Array (ALMA). ADFS-27 was selected from Herschel/Spectral and Photometric Imaging Receiver (SPIRE) and APEX/LABOCA data as an extremely red “870 μm riser” (i.e., {S}250μ {{m}} {S}350μ {{m}} {S}500μ {{m}

An essential difference between the western and eastern provinces of the Roman Empire is the fact that sophisticated urban cultures had developed in Asia Minor and the Levant centuries before the Romans arrived. Underlying the Hellenized, and later Roman, veneer was a myriad of older local traditions and languages, which had an immense impact upon

We examine the rotation rates, sizes and star formation (SF) efficiencies of a representative population of simulated disc galaxies extracted from the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) suite of cosmological hydrodynamic simulations. These simulations include efficient, but energetically feasible supernova feedback, but

The WMAP results on the scalar spectral index n and its running with scale, though preliminary, open a very interesting window to physics at very high energies. We address the problem of finding simple inflaton potentials, well motivated by particle physics, that can accommodate WMAP data.
