The second data release from the European Pulsar Timing Array I. The dataset and timing analysis

J. Antoniadis, S. Babak, A. -S. Bak Nielsen +66

Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1 - 100 nanohertz), which is intimately connected to a number of markers that can uniquely trac…

Multi-scale clustering in granular surface flows

D. Bonamy, F. Daviaud, L. Laurent +2

We investigate steady granular surface flows in a rotating drum and demonstrate the existence of rigid clusters of grains embedded in the flowing layer. These clusters are fractal…

The second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals

J. Antoniadis, P. Arumugam, S. Arumugam +97

We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…

The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals

J. Antoniadis, P. Arumugam, S. Arumugam +95

We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar T…

The second data release from the European Pulsar Timing Array II. Customised pulsar noise models for spatially correlated gravitational waves

J. Antoniadis, P. Arumugam, S. Arumugam +95

The nanohertz gravitational wave background (GWB) is expected to be an aggregate signal of an ensemble of gravitational waves emitted predominantly by a large population of coalesc…

Even a precessing clock is right twice per orbit -- The super-periods of eRO-QPE2 and challenges for quasi-periodic eruption orbital models

R. Arcodia, G. Miniutti, J. Chakraborty +25

We present OC (``observed minus calculated'') timing analysis of the quasi-periodic eruption (QPE) source eRO-QPE2 with a multi-mission X-ray campaign, which includes 32 observe…
