A review is given of various theoretical approaches for the equation of state (EoS) of dense
matter, relevant for the description of core-collapse supernovae, compact stars, and compact …

We summarize our current knowledge of neutron-star masses and radii. Recent
instrumentation and computational advances have resulted in a rapid increase in the …

Evidence for a low-frequency stochastic gravitational-wave background has recently been
reported based on analyses of pulsar timing array data. The most likely source of such a …

We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The
release contains observations of 32 pulsars obtained using the 64-m Parkes …

In this paper, we describe the International Pulsar Timing Array second data release, which
includes recent pulsar timing data obtained by three regional consortia: the European Pulsar …

We analyze 24 binary radio pulsars in the North American Nanohertz Observatory for
Gravitational Waves (NANOGrav) nine-year data set. We make 14 significant measurements …

The highly stable spin of neutron stars can be exploited for a variety of (astro) physical
investigations. In particular, arrays of pulsars with rotational periods of the order of …

Neutron stars are composed of the densest form of matter known to exist in our Universe, the
composition and properties of which are still theoretically uncertain. Measurements of the …

Microscopic calculations of neutron matter based on nuclear interactions derived from chiral
effective field theory, combined with the recent observation of a 1.97±0.04 M☉ neutron star …

Neutron stars are valuable laboratories for the study of dense matter. Recent observations
have uncovered both massive and low-mass neutron stars and have also set constraints on …
