Sub-Eddington accreting supermassive primordial black holes explain Little Red Dots
Hai-Long Huang, Jun-Qian Jiang, Jibin He +2
The James Webb Space Telescope (JWST) has uncovered an abundant population of compact, extremely red, and X-ray weak objects at , knows as ``Little Red Dots" (LRDs). The…
Scale-dependence in CDM parameters inferred from the CMB: a possible sign of Early Dark Energy
Jun-Qian Jiang
The early dark energy (EDE) model is one of the promising solutions to the Hubble tension. One of the successes of the EDE model is that it can provide a similar fit to the CDM…
Towards primordial gravitational waves and in light of BICEP/Keck, DESI BAO and Hubble tension
Hao Wang, Gen Ye, Jun-Qian Jiang +1
Recent observational data seem to show a evidence for an evolving dark energy (DE) against the cosmological constant, so the standard CDM model. In this paper, we p…
Explanation of high redshift luminous galaxies from JWST by early dark energy model
Jun-Qian Jiang, Weiyang Liu, Hu Zhan +1
Recent observations from the James Webb Space Telescope (JWST) have uncovered massive galaxies at high redshifts, with their abundance significantly surpassing expectations. This f…
High-redshift JWST massive galaxies and the initial clustering of supermassive primordial black holes
Hai-Long Huang, Jun-Qian Jiang, Yun-Song Piao
In this paper, we show that the initial clustering of supermassive primordial black holes (SMPBHs) beyond a Poisson distribution can efficiently enhance the matter power spectrum,…
Search for the non-linearities of gravitational wave background in NANOGrav 15-year data set
Jun-Qian Jiang, Yun-Song Piao
The recently reported signal of common red noise between pulsars by several pulsar timing array collaborations has been thought as evidence of the stochastic gravitational wave bac…
