Intrinsic Shapes of Very Flat Elliptical Galaxies
Intrinsic Shapes Flat Elliptical Galaxies
2011/1/11
Photometric data from the literature is combined with triaxial mass models to derive variation in the intrinsic shapes of the light distribution of elliptical galaxies NGC 720, 2768 and 3605. The infe...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
effective theory of inflation new shapes of non-Gaussianity
2010/11/16
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
Modelling the shapes of the largest gravitationally bound objects
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We combine the physics of the ellipsoidal collapse model with the excursion set theory to study the shapes of dark matter halos. In particular, we develop an analytic approximation to the nonlinear ev...
The shapes of light curves of Mira-type variables
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
Using a sample of 454 mira light curves from the ASAS survey we study the shape of the light variations in this kind of variable stars.
EXPERIMENTAL DIFFICULTIES IN DETERMINATION OF THE SPECTRAL LINE SHAPES EMITTED FROM PLASMA
LINE SHAPES PLASMA
2009/4/8
From the plasma radiation and from spectral line profiles it is possible
to obtain many particulars about the plasma conditions. The particulars are,
for example, concentration of the neutral or cha...
