QuickGWecc: Fast Bayesian pipeline for searching eccentric binaries in pulsar timing array data
Lankeswar Dey, Bence Bécsy, Abhimanyu Susobhanan +1
The paper introduces QuickGWecc, a fast Bayesian pipeline that extends the QuickCW framework to efficiently search for continuous gravitational waves from eccentric supermassive bl…
Probing Graviton Mass with MeerKAT PTA and SKA--PTA Forecasts
Zhi-Chao Zhao, Sai Wang
The paper uses data from the MeerKAT pulsar timing array to set upper limits on the graviton mass and forecasts that the upcoming SKA pulsar timing array could improve these limits…
Astrophysical Population Coordinates for Supermassive Black Hole Binaries in Pulsar Timing Array Inference
Yikun Li, Muhammad Ahmad, Shaoguang Guo +1
The paper develops a phenomenological forward model for the population of supermassive black‑hole binaries as observed by pulsar timing arrays, defining three population coordinate…
Bias from small-scale leakage in Pulsar Timing Array maps
Federico Semenzato, Nicola Bellomo, Alvise Raccanelli +1
The paper identifies and analytically quantifies a systematic bias called “small‑scale leakage” that arises when pulsar timing array analyses reconstruct only large‑scale anisotrop…
Cross-Correlating the Universe: The Gravitational Wave Background and Large-Scale Structure
Federico Semenzato, J. Andrew Casey-Clyde, Chiara M. F. Mingarelli +4
The paper proposes using cross‑correlations between gravitational‑wave background anisotropy maps and galaxy surveys to detect the imprint of unresolved supermassive black‑hole bin…
