Abstract CASA, the Common Astronomy Software Applications, is primary data processing software for Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very (VLA), frequently used also other radio telescopes. The CASA can handle from single-dish, aperture-synthesis, Long Baseline Interferometery (VLBI) One of its core functionalities to support calibration imaging pipelines AL...

This paper uses the National Family Health Survey (NFHS) data collected in 1992-93 to estimate the determinants of child (aged 6 to 14) enrollment and educational attainment of a recent cohort (aged 15 to 19) in India. The analysis produces five major results. First, using an index of assets as a proxy for household wealth shows enormous gaps between the enrollment and attainment of children fr...

This paper introduces a class of graphs deened as the models of a peculiar kind of linear bounded machines that read their input performing all computations on work tapes. It is proven that this class is closed, up to observational equivalence, under synchronized product. The rst{order theory of these graphs is investegated and shown to be undecidable. The latter result extends to any logic in ...

Aims. Globular clusters have been alternatively predicted to host intermediate-mass black holes (IMBHs) or nearly impossible to form and retain them in their centres. Over the last decade enough theoretical and observational evidence have accumulated to believe that many, if not all, galactic globular clusters host IMBHs in the centres, just like galaxies do. The well-established galactic bulge...

Simulated wide-field images are becoming an important part of observational astronomy, either to prepare for new surveys or to test measurement methods. In order to efficiently explore vast parameter spaces, the computational speed of simulation codes is a central requirement to their implementation. We introduce the Ultra Fast Image Generator (UFig) which aims to bring wide-field imaging simul...

Of the light nuclides observed in the universe today, D, He, He, and Li are relics from its early evolution. The primordial abundances of these relics, produced via Big Bang Nucleosynthesis (BBN) during the first half hour of the evolution of the universe provide a unique window on Physics and Cosmology at redshifts ∼ 10. Comparing the BBN-predicted abundances with those inferred from observati...

We compute the spectral correlation function (SCF) of CO J=1–0 maps of molecular cloud complexes. The SCF is a power law over approximately an order of magnitude in spatial separation in every map. The power law slope of the SCF, α, its normalization, S0(1pc), and the spectral line width averaged over the whole map, σv, are computed for all the observational maps. The values of α , S0(1pc) and ...
