Primordial black hole formation by vacuum bubbles II
Heling Deng
The discoveries of LIGO/Virgo black holes in recent years have revitalized the study of primordial black holes. In this work, we investigate a mechanism where primordial black hole…
Spiky CMB distortions from primordial bubbles
Heling Deng
Primordial bubbles that possibly nucleate through quantum tunneling during inflation in a multidimensional potential might have left some relic detectable at the present time. Thes…
Eternal Inflation in Swampy Landscapes
Jose J. Blanco-Pillado, Heling Deng, Alexander Vilenkin
The much-discussed swampland conjectures suggest significant constraints on the properties of string theory landscape and on the nature of the multiverse that this landscape can su…
CMB spectral distortions from black holes formed by vacuum bubbles
Heling Deng, Alexander Vilenkin, Masaki Yamada
Vacuum bubbles may nucleate and expand during the cosmic inflation. When inflation ends, the bubbles run into the ambient plasma, producing strong shocks followed by underdensity w…
Can Light Dark Matter Solve the Core-Cusp Problem?
Heling Deng, Mark P. Hertzberg, Mohammad Hossein Namjoo +1
Recently there has been much interest in light dark matter, especially ultra-light axions, as they may provide a solution to the core-cusp problem at the center of galaxies. Since…
