Manifestly gauge invariant theory of the nonlinear cosmological perturbations in the leading order of the gradient expansion
nonlinear cosmological perturbation, gauge invariance, non-Gaussianity PACS number(s):98.80.Cq
2011/9/29
In the full nonlinear cosmological perturbation theory in the leading order of the gradient expansion, all the types of the gauge invariant perturbation variables are defined. The metric junction cond...
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
cosmic rays – gamma rays ISM – ISM general
2010/11/10
We report an analysis of the interstellar-ray emission in the third Galactic quadrant measured
by the Fermi Large Area Telescope. The window encompassing the Galactic plane from longitude 210◦ ...
Old open clusters and the Galactic metallicity gradient: Berkeley 20, Berkeley 66, and Tombaugh 2
Galaxy disc – Hertzsprung-Russell (HR) diagram – open clusters and associations
2010/11/15
To study the crucial range of Galactocentric distances between 12 and 16 kpc, where little
information is available, we have obtained V I CCD imaging of Berkeley 20 and BV I CCD
imaging of Berkeley ...
Measurement of a Metallicity Gradient in a z=2 Galaxy: Implications for Inside-Out Assembly Histories
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We present near-infrared imaging spectroscopy of the strongly-lensed z=2.00 galaxy SDSS J120601.69+514227.8 (`the Clone arc'). Using OSIRIS on the Keck 2 telescope with laser guide star adaptive optic...

GRADIENT OF MEAN MASS OF A STAR IN THE FIELD OF GLOBULAR CLUSTERS
globular clusters general-Stars fundamental parameters (masses)
2009/2/16
Based on the relevant available data, the distributions of masses
and apparent magnitudes of stars belonging to globular star clusters are simulated.
The simulations are aimed at examining the in°ue...
