\(T_{boom}\) seeks to explain why a body with a given amount of temperature particles (ie. of a particular temperature) are radiating (not just the electromagnetic radiation). The black body is nuclear.
However, the derivation for \(v_{boom}\) was not for a specified type of particles, \(v_{boom}\) applies for the charge content of a body as well as its gravity particle content. This means a body with sufficient electron charges will also be radiating. The equivalent of temperature measure will be its charge capacity. In a similar way, a body containing free gravity particles will also be radiating when it has high gravity particle content.
So, there is temperature, gravity temperature and charge temperature and the respective radiations due to each content of particles. Charge temperature radiation is more likely to be observed from metallic bodies capable of holding charges, and gravity temperature radiation is more likely from crystals that hold gravity particles.
Good night.
