Stochastic gravitational-wave background search using data from five pulsar timing arrays

Wang-Wei Yu, Bruce Allen

Using public pulse time-of-arrival data from five pulsar timing arrays (PTAs), we search for a stationary, isotropic, and unpolarized nHz stochastic gravitational-wave background (…

No-go guide for the Hubble tension: late-time or local-scale new physics

Lu Huang, Shao-Jiang Wang, Wang-Wei Yu

The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant () tension, which manifests itself as the sound-horizon ($r_…

Explaining Pulsar Timing Array Observations with Primordial Gravitational Waves in Parity-Violating Gravity

Chengjie Fu, Jing Liu, Xing-Yu Yang +2

The pulsar timing array (PTA) collaborations have recently suggested the presence of a gravitational wave background at nano-Hertz frequencies. In this paper, we explore potential…

Searching for double-peak and doubly broken gravitational-wave spectra from Advanced LIGO-Virgo's first three observing runs

Wang-Wei Yu, Shao-Jiang Wang

The current LIGO-Virgo observing run has been pushing the sensitivity limit to touch the stochastic gravitational-wave backgrounds (SGWBs). However, no significant detection has be…

First detection of the Hubble variation correlation and its scale dependence

Wang-Wei Yu, Li Li, Shao-Jiang Wang

The sample variance due to our local density fluctuations in measuring our local Hubble-constant () can be reduced to the percentage level by choosing the Hubble-flow type Ia…

No-go guide for late-time solutions to the Hubble tension: Matter perturbations

Rong-Gen Cai, Zong-Kuan Guo, Shao-Jiang Wang +2

The Hubble tension seems to be a crisis with discrepancy between the most recent local distance ladder measurement from type Ia supernovae calibrated by Cepheids and the g…

Parity violation in stochastic gravitational wave background from inflation

Rong-Gen Cai, Chengjie Fu, Wang-Wei Yu

We study the inflationary implications of a novel parity-violating gravity model, which modifies the teleparallel equivalent of general relativity by introducing the Nieh-Yan term…

No-go guide for the Hubble tension : Late-time solutions

Rong-Gen Cai, Zong-Kuan Guo, Shao-Jiang Wang +2

The Hubble tension, if not caused by any systematics, could be relieved or even resolved from modifying either the early-time or late-time Universe. The early-time modifications ar…

Chameleon dark energy can resolve the Hubble tension

Rong-Gen Cai, Zong-Kuan Guo, Li Li +2

Values of the Hubble constant between the direct measurements from various independent local observations and that inferred from the cosmic microwave background with the -cold-d…

Do the observational data favor a local void?

Rong-Gen Cai, Jia-Feng Ding, Zong-Kuan Guo +2

The increasing tension between the different local direct measurements of the Hubble expansion rate and that inferred from the Cosmic Microwave Background observation by -Cold-D…
