Constraints on Ultralight Scalar and Dark Photon Dark Matter from PPTA-DR3 and EPTA-DR2
Xiao-Song Hu, Siyuan Chen, Kuo Liu +18
The cold dark matter model successfully describes the Universe on large scales, yet faces challenges at sub-galactic scales. Ultralight dark matter (ULDM), with particle masses aro…
Prospects for gravitational-wave detection and supermassive black hole astrophysics with pulsar timing arrays
V. Ravi, J. S. B. Wyithe, R. M. Shannon +1
Large-area sky surveys show that massive galaxies undergo at least one major merger in a Hubble time. Ongoing pulsar timing array (PTA) experiments are aimed at measuring the gravi…
Binary super-massive black hole environments diminish the gravitational-wave signal in the pulsar timing band
V. Ravi, J. S. B. Wyithe, R. M. Shannon +2
We assess the effects of super-massive black hole (SMBH) environments on the gravitational-wave (GW) signal from binary SMBHs. To date, searches with pulsar timing arrays for GWs f…
Gravitational-wave Limits from Pulsar Timing Constrain Supermassive Black Hole Evolution
R. M. Shannon, V. Ravi, W. A. Coles +14
The formation and growth processes of supermassive black holes (SMBHs) are not well constrained. SMBH population models, however, provide specific predictions for the properties of…
Does a 'stochastic' background of gravitational waves exist in the pulsar timing band?
V. Ravi, J. S. B. Wyithe, G. Hobbs +4
We investigate the effects of gravitational waves (GWs) from a simulated population of binary super-massive black holes (SMBHs) on pulsar timing array datasets. We construct a dist…
