The second data release from the European Pulsar Timing Array: IV. Implications for massive black holes, dark matter and the early Universe
J. Antoniadis, P. Arumugam, S. Arumugam +111
The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and fir…
Practical approaches to analyzing PTA data: Cosmic strings with six pulsars
Hippolyte Quelquejay Leclere, Pierre Auclair, Stanislav Babak +69
We search for a stochastic gravitational wave background (SGWB) generated by a network of cosmic strings using six millisecond pulsars from Data Release 2 (DR2) of the European Pul…
Repeated Gravitational Wave Bursts from Cosmic Strings
Pierre Auclair, Danièle A. Steer, Tanmay Vachaspati
A characteristic observational signature of cosmic strings are short duration gravitational wave (GW) bursts. These have been searched for by the LIGO-Virgo-KAGRA (LVK) collaborati…
Cosmic string bursts in LISA
Pierre Auclair, Stanislav Babak, Hippolyte Quelquejay Leclere +1
Cosmic string cusps are sources of short-lived, linearly polarised gravitational wave bursts which can be searched for in gravitational wave detectors. We assess the capability of…
Spatial Curvature from Super-Hubble Cosmological Fluctuations
Baptiste Blachier, Pierre Auclair, Christophe Ringeval +1
We revisit how super-Hubble cosmological fluctuations induce, at any time in the cosmic history, a non-vanishing spatial curvature of the local background metric. The random nature…
