I see how it is derived for the BH and in case of Unruh effect.(adsbygoogle = window.adsbygoogle || []).push({});

In Unruh effect it is a function of acceleration

In case of BH distance to the event horizon plays important role

What I cant find, however, how tidal forces should be taken into account. For example, in the universe with DE (accelerated expansion) the temperature never falls to 0, because there will be always hawking-like radiation from the cosmological horizons

I dont see how it is derived. The metric is not schwarzschild so formula for Hawkings radiation can not be used. Formula for Unruh radiation uses 'a', acceleration... I am blocked.
