Structure formation with primordial black holes: collisional dynamics, binaries, and gravitational waves
M. Sten Delos, Antti Rantala, Sam Young +1
Primordial black holes (PBHs) could compose the dark matter content of the Universe. We present the first simulations of cosmological structure formation with PBH dark matter that…
Computing the abundance of primordial black holes
Sam Young
An accurate calculation of their abundance is crucial for numerous aspects of cosmology related to primordial black holes (PBHs). For example, placing constraints on the primordial…
Primordial black hole formation during the QCD phase transition: threshold, mass distribution and abundance
Ilia Musco, Karsten Jedamzik, Sam Young
Primordial black hole (PBH) formation during cosmic phase transitions and annihilation periods, such as the QCD transition or the -annihilation, is thought to be particular…
Primordial black hole isocurvature modes from non-Gaussianity
Raphaël van Laak, Sam Young
Primordial black holes (PBHs) are black holes that might have formed in high density regions in the early universe. The presence of local-type non-Gaussianity can lead to large-sca…
Inflation with two-form field: the production of primordial black holes and gravitational waves
Tomohiro Fujita, Hiromasa Nakatsuka, Ippei Obata +1
Antisymmetric tensor field (two-form field) is a ubiquitous component in string theory and generally couples to the scalar sector through its kinetic term. In this paper, we propos…
Peaks and primordial black holes: the effect of non-Gaussianity
Sam Young
In light of recent developments in the field, we re-evaluate the effect of local-type non-Gaussianity on the primordial black hole (PBH) abundance (and consequently, upon constrain…
