A common feature of the X-ray bubbles observed in Chandra images of some "cooling flow" clusters is that they appear to be surrounded by bright, cool shells. Temperature maps of a few nearby luminous ...
Interpreting the relationship between galaxy luminosity, color, and environment
galaxy luminosity color environment
2014/12/24
We study the relationship between galaxy luminosity, color, and environment in a cosmological simulation of galaxy formation. Using a simple prescription to assign colors and luminosities to simulated...
Relationship of neutrino and graviton dark matter
Neutrino field Neutrino energy loss The quantum gravitational field Graviton energy Dark matter

This paper discusses the neutrino field in the space of the universe. According to the neutrino energy shocks in the fact that the neutrino field principle the formation of quantum gravity.According t...
Measuring a cosmological distance-redshift relationship using only gravitational wave observations of binary neutron star coalescences
neutron stars gravitational waves cosmology
2011/10/14
Detection of gravitational waves from the inspiral phase of binary neutron star coalescence will allow us to measure the effects of the tidal coupling in such systems. These effects will be measurable...
Galaxy clustering in the CFHTLS-Wide: the changing relationship between galaxies and haloes since z ~ 1.2
Cosmology: observations - large-scale structure of Universe - Galaxies: distances and redshifts - Galaxies: evolution - Galaxies: haloes
2011/9/27
We present a detailed investigation of the changing relationship between galaxies and the dark matter haloes they inhabit from z ~ 1.2 to the present day. We do this by comparing precise galaxy cluste...
We study the mass-density relationship n m^x in molecular cloud clumps, considering various relations between the gravitational, kinetic, internal and magnetic energy. Clumps are described statistical...
The Relationship Between Molecular Gas and Star Formation in Low-Mass E/S0 Galaxies
Relationship Between Molecular Gas Star Formation
2010/11/11
We consider the relationship between molecular-gas and star-formation sur-face densities in 19 morphologically defined E/S0s with stellar mass . 4 × 1010M⊙, paying particular attention to those found ...
Accurate AGN black hole masses and the scatter in the M_{bh} - L_{bulge} relationship
black hole physics galaxies active galaxies bulges galaxies fundamental parameters galaxies nuclei quasars emission lines
2010/3/9
A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation...

Relationship between Interplanetary (IP) Parameters and Geomagnetic Indices during IP Shock Events of 2005
IP parameters IP shocks solar–terrestrial relationship
2009/5/6
In the present study, we investigate the possible relationship
of IP parameters of solar wind and interplanetary magnetic field with
ground-based geomagnetic indices. To carry out the study, we take...
MUTUAL RELATIONSHIP OF OSCILLATIONS IN THE FREQUENCY RANGE 3.6 mHz TO 22 mHz IN THE SOLAR CHROMOSPHERE
Sun chromosphere-Sun oscillations
2009/2/20
High frequency acoustic oscillations were suggested as the source
of mechanical heating in the chromosphere. In this work the radial component of
the oscillations in the frequency interval 3 mHz to ...
