This book presents a comprehensive review of the subject of gravitational effects in quantum
field theory. Although the treatment is general, special emphasis is given to the Hawking …

Primordial black holes are under intense scrutiny since the detection of gravitational waves
from mergers of Solar-mass black holes in 2015. More recently, the development of …

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite has yielded
unprecedented measurements of the soft gamma-ray spectrum of our Galaxy. Here we use …

We derive the strongest constraint on the fraction of dark matter that can be composed of low
mass primordial black holes by using the observation of the Galactic Center 511 keV γ-ray …

As the only dark matter candidate that does not invoke a new particle that survives to the
present day, primordial black holes (PBHs) have drawn increasing attention recently. Up to …

Hawking evaporation of black holes in the early Universe is expected to copiously produce
all kinds of particles, regardless of their charges under the Standard Model gauge group. For …

Primordial black holes can have substantial spin—a fundamental property that has a strong
effect on its evaporation rate. We conduct a comprehensive study of the detectability of …

We update the constraints on the fraction of the Universe going into primordial black holes in
the mass range 10 9–10 17 g associated with the effects of their evaporations on big bang …

Primordial black holes (PBHs) from the early Universe have been connected with the nature
of dark matter and can significantly affect cosmological history. We show that coincidence …

We present the new version v2. 0 of the public code BlackHawk designed to compute the
Hawking radiation of black holes, with both primary and hadronized spectra. This new …
