The discovery of pulsars opened a new research field that allows studying a wide range of
physics under extreme conditions. More than 3,000 pulsars are currently known, including …

Fast radio bursts (FRBs), millisecond-duration bursts prevailing in the radio sky, are the
latest large puzzle in the Universe and have been a subject of intense observational and …

We report on Bayesian parameter estimation of the mass and equatorial radius of the
millisecond pulsar PSR J0030+ 0451, conditional on pulse-profile modeling of Neutron Star …

Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear
physicists because their attributes can be used to determine the properties of the dense …

Fewer than a dozen gamma-ray pulsars were known when the Fermi Gamma-ray Space
Telescope was launched on 2008 June 11, and the extent and diversity of the population …

We review open questions and prospects for progress in ultrahigh-energy cosmic ray
(UHECR) research, based on a series of discussions that took place during the “The High …

Neutron stars are natural physical laboratories allowing us to study a plethora of
phenomena in extreme conditions. In particular, these compact objects can have very strong …

We study the electrodynamics of a kinetically mixed dark photon cloud that forms through
superradiance around a spinning black hole, and design strategies to search for the …

Since pulsars were discovered as emitters of bright coherent radio emission more than half
a century ago, the cause of the emission has remained a mystery. In this Letter we …

We present an analysis of the effects of uncertainties in the atmosphere models on the
radius, mass, and other neutron star parameter constraints for the NICER observations of …
