A Density Independent Formulation of Smoothed Particle Hydrodynamics
Density Independent Formulation Smoothed Particle Hydrodynamics Cosmology and Extragalactic Astrophysics
2012/2/21
In the standard formulation of the smoothed particle hydrodynamics (SPH), it is assumed that the local density distribution is differentiable. This assumption is used to derive the spatial derivatives...
Model-Independent Comparisons of Pulsar Timings to Scalar-Tensor Gravity
General Relativity Gravity Gravitation Scalar-Tensor Tensor-Scalar Neutron Stars Pulsars Binary Pulsars Double Pulsar
2011/10/14
Observations of pulsar timing provide strong constraints on scalar-tensor theories of gravity, but these constraints are traditionally quoted as limits on the microscopic parameters (like the Brans-Di...
A Model Independent Method to Study Dark Matter induced Leptons and Gamma rays
A Model Independent Method to Study Dark Matter induced Leptons and Gamma rays
2011/10/17
We propose a novel method to directly determine dark matter induced electron/positron spectrum at the source from experimental measurements at the earth, without reference to specific particle physics...

Beyond Einstein: Cosmological Model Independent Modified Gravity
2011/10/8
Model-independent parametrisations of modified gravity have attracted a lot of attention over the past few years; numerous combinations of experiments and observables have been suggested to constrain ...

Cluster morphologies and model-independent Y_SZ estimates from Bolocam Sunyaev-Zel'dovich images
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present initial results from our ongoing program to image the Sunyaev-Zel'dovich (SZ) effect in galaxy clusters at 143 GHz using Bolocam; five clusters and one blank field are described in this man...
Spectroscopic Studies of Solar Corona VI: Trend in Line-width Variation of Coronal Emission Lines with Height Independent of the Structure of Coronal Loops

2010/9/16
We have obtained spectroscopic observations in coronal emission lines by choosing two lines simultaneously, one [Fe x] 6374Å and the other [Fe xi] 7892Å or [Fe xiii] 10747Å or [Fe xi...

Spectroscopic observations of close binary star V455 Cygni reveal
many lines that originate in interstellar and circumstellar medium and the atmo-
sphere of the Earth; we found over two hundred such...
