I have been calculating the solar rotation rate from the population of halo stars. Halo stars are thought to have no net rotation, so by finding an average...

I have enjoyed the give-and-take of the thread entitled "Good News for the Big Bang Theory", and I intend to keep contributing to it when I think I have...

There are much more discussions on the related issue. Visit http://dipoleantigravity.blogspot.com/2007/04/gpb-raw-data.html

It has not escaped my attention that one cannot revise the distance to SgrA* without revising the Cepheid scale and with it the value of Hubble's constant, and...

A recent post by Andrew Yee, titled "Scientists elucidate the origin of the darkest galaxies in the universe", says that a group led by Kazantzidis shows that...

Hi, anybody know how to delete a table column from a fits binary table extension in a python script, under pyraf/stsdas/pyfits or whatever? There don't seem...

Please excuse a newbie if this is common but I was looking out the window at night and noticed a long strange reflection on the Mississippi River. I...

Some spiral galaxies, such as*Andromeda and Milky Way, are barred. So what is the matter*distribution of such barred galaxies towards the hub, especially...

Hi fella's My question arises because I understand the solar wind consists of free protons "p+" and electrons "e-" emitted in vast quantities from the sun. The...

Hi, MNRAS citation rules stipulate that 3-author papers be cited with full authors on first cite, but First et al. thereafter. However, with the official...

Accordingly to book "Galactic Dynamics" half of all the disk galaxies contain bars (page 399). What I first try to understand are galaxies without a bar. A...

Hi I am studying for an astrophysics degree and am carrying out a short theoretical study considering the radiation shielding problems associated with placing...

Doppler Tests on Local Stars Our knowledge of stellar kinematics and cosmology is almost entirely dependent on red shift measurements. We assume that the...

According to CDM and MOND the Milky way's rotation curve is flat or slightly rising at the radius of the Sun. The Newtonian prediction is for a slope of about...

When a photon travels across space, it gets redshifted -- its wavelength increases, due to the expansion of space. Consequently, the frequency of the photon...

I am trying to establish precisely how the 'best fit' EFE has changed over historical time (i.e. 1916 to now). I think I have a reasonable idea, but am not...

Once again I'm unable to do the math, but I do have a fairly good geometry visualization skill... The spirals of galaxies are presumably density maximum...
