Searching for gravitational wave burst in PTA data with piecewise linear functions
Heling Deng, Bence Bécsy, Xavier Siemens +2
Transient gravitational waves (aka gravitational wave bursts) within the nanohertz frequency band could be generated by a variety of astrophysical phenomena such as the encounter o…
Simulating cosmic string loop captured by a rotating black hole
Heling Deng, Andrei Gruzinov, Yuri Levin +1
We study the dynamics of a cosmic string loop captured by a rotating black hole, ignoring string reconnections. A loop is numerically evolved in Kerr spacetime, with the result tha…
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…
Primordial black hole formation by vacuum bubbles
Heling Deng, Alexander Vilenkin
Vacuum bubbles may nucleate during the inflationary epoch and expand, reaching relativistic speeds. After inflation ends, the bubbles are quickly slowed down, transferring their mo…
Primordial black hole and wormhole formation by domain walls
Heling Deng, Jaume Garriga, Alexander Vilenkin
In theories with a broken discrete symmetry, Hubble sized spherical domain walls may spontaneously nucleate during inflation. These objects are subsequently stretched by the inflat…
