Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

Periodic interstellar scintillation variations of PSRs~J06130200 and J0636+5128 associated with the Local Bubble shell

Yulan Liu, Robert A. Main, Joris P. W. Verbiest +11

Annual variations of interstellar scintillation can be modelled to constrain parameters of the ionized interstellar medium. If a pulsar is in a binary system, then investigating th…

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…

The Thousand-Pulsar-Array programme on MeerKAT -- VIII. The subpulse modulation of 1198 pulsars

X. Song, P. Weltevrede, A. Szary +13

We report on the subpulse modulation properties of 1198 pulsars using the Thousand-Pulsar-Array programme on MeerKAT. About 35% of the analysed pulsars exhibit drifting subpulses w…
