Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

Annalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Probing neutron star physics using accreting neutron stars

EPJ Web of Conferences, 2010
We give an obervational overview of the accreting neutron stars systems as probes of neutron star physics. In particular we focus on the results obtained from the periodic timing of accreting millisecond X-ray pulsars in outburst and from the ...

Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 with FAST and Arecibo

The Astrophysical Journal Supplement Series, 2023
We report on a comprehensive multiwavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact noneclipsing “black widow” pulsar.

Modeling pulse profiles of accreting millisecond pulsars [PDF]

, 2008
I review the basic observational properties of accreting millisecond pulsars that are important for understanding the physics involved in formation of their pulse profiles. I then discuss main effects responsible for shaping these profiles.

Studying Millisecond Pulsars in X-rays [PDF]

, 2006
Millisecond pulsars represent an evolutionarily distinct group among rotation-powered pulsars. Outside the radio band, the soft X-ray range ($\sim 0.1$--10 keV) is most suitable for studying radiative mechanisms operating in these fascinating objects.

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters

The Astrophysical Journal
Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.

The GMRT High Resolution Southern Sky Survey for Pulsars and Transients. IV. Discovery of Four New Pulsars with an FFA Search

The Astrophysical Journal, 2023
The fast Fourier transform (FFT) based periodicity search methods provide an efficient way to search for millisecond and binary pulsars but encounter significant sensitivity degradation while searching for long period and short duty cycle pulsars.
