Full analysis of the scalar-induced gravitational waves for the curvature perturbation with local-type non-Gaussianities

Chen Yuan, De-Shuang Meng, Qing-Guo Huang

Primordial black holes (PBHs) are supposed to form through the gravitational collapse of regions with large density fluctuations. The formation of PBHs inevitably leads to the emis…

Cosmological Interpretation for the Stochastic Signal in Pulsar Timing Arrays

Yu-Mei Wu, Zu-Cheng Chen, Qing-Guo Huang

The pulsar timing array (PTA) collaborations have recently reported compelling evidence for the presence of a stochastic signal consistent with a gravitational-wave background. In…

Implications for the non-Gaussianity of curvature perturbation from pulsar timing arrays

Lang Liu, Zu-Cheng Chen, Qing-Guo Huang

The recently released data by pulsar timing array (PTA) collaborations present strong evidence for a stochastic signal consistent with a gravitational-wave background. Assuming thi…

Implications for the Supermassive Black Hole Binaries from the NANOGrav 15-year Data Set

Yan-Chen Bi, Yu-Mei Wu, Zu-Cheng Chen +1

NANOGrav, EPTA, PPTA, and CPTA have announced the evidence for a stochastic signal from their latest data sets. Supermassive black hole binaries (SMBHBs) are supposed to be the mos…

Pulsar timing residual induced by ultralight tensor dark matter

Yu-Mei Wu, Zu-Cheng Chen, Qing-Guo Huang

Ultralight boson fields, with a mass around , are promising candidates for the elusive cosmological dark matter. These fields induce a periodic oscillation of th…
