This requires the gas to avoid cooling and to remain at temperatures near T=10^4 K.  We show that this condition can be satisfied in the presence of a sufficiently strong primordial magnetic field, which heats the collapsing gas via ambipolar diffusion.  If the field has a strength above B = 3.6 (comoving) nG, the collapsing gas is kept warm (T=10^4K) until it reaches the critical","authors_text":"Carnegie Mellon University), Kanhaiya Pandey (Raman Research Institute), Shiv K.
