How a galaxy regulates its SNe energy into different interstellar/circumgalactic medium components strongly affects galaxy evolution .
Based on the JVLA D-configuration C- ( 6 GHz ) and L-band ( 1.6 GHz ) continuum observations , we perform statistical analysis comparing multi-wavelength properties of the CHANG-ES galaxies .
The high-quality JVLA data and edge-on orientation enable us for the first time to include the halo into the energy budget for a complete radio-flux-limited sample .
We find tight correlations of L _ { radio } with the mid-IR-based SFR .
The normalization of our I _ { 1.6 GHz } / { W~ { } Hz ^ { -1 } } - { SFR } relation is \sim 2-3 times of those obtained for face-on galaxies , probably a result of enhanced IR extinction at high inclination .
We also find tight correlations between L _ { radio } and the SNe energy injection rate \dot { E } _ { SN ( Ia + CC ) } , indicating the energy loss via synchrotron radio continuum accounts for \sim 0.1 \% of \dot { E } _ { SN } , comparable to the energy contained in CR electrons .
The integrated C-to-L-band spectral index is \alpha \sim 0.5 - 1.1 for non-AGN galaxies , indicating a dominance by the diffuse synchrotron component .
The low-scatter L _ { radio } - { SFR } / L _ { radio } - \dot { E } _ { SN ( Ia + CC ) } relationships have super-linear logarithmic slopes at \sim 2 ~ { } \sigma in L-band ( 1.132 \pm 0.067 / 1.175 \pm 0.102 ) while consistent with linear in C-band ( 1.057 \pm 0.075 / 1.100 \pm 0.123 ) .
The super-linearity could be naturally reproduced with non-calorimeter models for galaxy disks .
Using Chandra halo X-ray measurements , we find sub-linear L _ { X } - L _ { radio } relations .
These results indicate that the observed radio halo of a starburst galaxy is close to electron calorimeter , and a galaxy with higher SFR tends to distribute an increased fraction of SNe energy into radio emission ( than X-ray ) .
