Query: Hawking radiation from nonrotating singularity-free black holes in
  conformal gravity   We study the sparsity of Hawking radiation from nonrotating singularity-free
black holes in conformal gravity. We give a rigorous bound on the greybody
factor for massless scalar field and calculate the sparsity of Hawking
radiation from the black hole. Besides, we investigate the dependence of the
greybody factor and the sparsity of Hawking radiation on the conformal
parameters. Our study shows that the Hawking radiation from the black hole is
extremely sparse. When the conformal parameters are large, the increase of
conformal parameters will lead to an even more sparse Hawking radiation, while
to a less sparse Hawking radiation if the conformal parameters are small.
