snorer.radiusInfluence¶

snorer.radiusInfluence(mBH)¶

Influence radius of a supermassive black hole

Parameters:

mBH : array_like
Supermassive black hole mass, $M_\odot$

Returns:

out : scalar/ndarray
Influence radisu, kpc. Out is scalar if the input is scalar.

Notes

This function evaluates the influence radius of a supermassive black hole $$ r_h = \frac{GM_{\rm BH}}{\sigma_s^2} $$ where sigma_s is the stellar dispersion near SMBH. See also snorer.M_sigma.
