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.

Prompted by the recent report of increased Swift/BAT activity from the neutron star X-ray transient XTE J1701-462 (ATel #3028), the source was observed for ~1.4 ks with the Rossi X-ray Timing Explorer on 2010 November 13 11:16 UTC. The average count rate from the PCA was 2.0+/-0.2 cts/s/PCU, consistent with the count rate from the Galactic ridge

We present deep optical photometry from the DECam imager on the 4 m Blanco telescope of over 12 deg2 around the Carina dwarf spheroidal, with complete coverage out to 1 deg and partial coverage extending out to 2.6 deg. Using a Poisson-based matched-filter analysis to identify stars from each of the three main stellar populations, old, intermediate
