Small-Scale Clustering of Primordial Black Holes: The Little Red Dot Mass Function and the High-Redshift Galaxy Tension
Borui Zhang, Wei-Xiang Feng, Haipeng An
Supermassive black holes (SMBHs) in "little red dots" (LRDs) discovered by the James Webb Space Telescope (JWST) may result from runaway mergers of primordial black holes (PBHs) in…
Particle productions during collisions of highly boosted bubble walls
Haipeng An, Hongyi Jiang
We investigate the production of particles much heavier than the characteristic scale of a cosmological first-order phase transition through collisions of highly boosted bubble wal…
Smoluchowski Coagulation Equation and the Evolution of Primordial Black Hole Clusters
Borui Zhang, Wei-Xiang Feng, Haipeng An
In arXiv:2507.07171, we demonstrate that the high-redshift supermassive black holes in the so-called "little red dots" discovered by James Webb Space Telescope (JWST) can be explai…
Inflationary phase transitions in the early Universe: A Bayesian study with space-based gravitational-wave detectors
Qingyuan Liang, Chen Yang, Haipeng An +1
Inflationary phase transitions can generate a stochastic gravitational-wave background that probes primordial physics. We study the detectability and parameter reconstruction of su…
Little Red Dots from Small-Scale Primordial Black Hole Clustering
Borui Zhang, Wei-Xiang Feng, Haipeng An
The James Webb Space Telescope (JWST) observations have identified a class of compact galaxies at high redshifts (), dubbed "little red dots" (LRDs). The…
Topological defects as effective dynamical dark energy
Haipeng An, Chengcheng Han, Borui Zhang
In this work, we consider the possibility that the dynamical dark energy hinted at by recent DESI data may be mimicked by the effects of additional components in the universe, pote…
Primordial Stochastic Gravitational Waves from Massive Higher-Spin Bosons
Haipeng An, Zhehan Qin, Zhong-Zhi Xianyu +1
Can a stationary stone radiate gravitational waves (GWs)? While the answer is typically "no" in flat spacetime, we get a "yes" in inflationary spacetime. In this work, we study the…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
