  Starburst galaxies are undergoing intense episodes of star formation. In
these galaxies, gas is ejected into the surrounding environment through winds
created by the effect of hot stars and supernova explosions. When interacting
with the intergalactic medium, these winds can produce strong shocks capable of
accelerating cosmic rays. The radiation from these cosmic rays mainly occurs in
radio and gamma rays. The radio halo can be characterized using the scale
height. We searched for the presence of radio halos in a sample of edge-on
starburst galaxies gathered from the MeerKAT 1.28 GHz Atlas of Southern Sources
in the IRAS Revised Bright Galaxy Sample. We selected a sample of 25 edge-on
galaxies from the original sample and modeled their disk and halo
contributions. We have detected and characterized 11 radio halos, seven of
which are reported here for the first time. We found that the halo scale
heights increase linearly with the radio diameters and this relation does not
depend on the star formation rate. All galaxies in our sample follow the
radio-infrared relation with a q parameter value of $2.5\pm0.1$. The dependence
of the halo luminosity on the star formation rate and the infrared luminosity
supports the hypothesis that the radio halos are the result of synchrotron
radiation produced by relativistic electrons and points toward the fact that
the star formation activity plays a crucial role in halo creation. The average
scale height of 1 kpc implies a dynamical range of 4 Myr, several orders of
magnitude greater than the synchrotron losses for electrons of 10 TeV. This
suggests that some process must exist to reaccelerate cosmic rays in the halo
if gamma-ray emission of a leptonic origin is detected from the halo. According
to the relation between the radio and gamma-ray luminosities, we found that NGC
4666 is a potential gamma-ray source for future observations.
