Galactic Center Pulsars with the ngVLA

TL;DR

The paper discusses how the ngVLA telescope's high-frequency sensitivity will enable new discoveries of pulsars in the Galactic Center, including potential tests of black hole physics and General Relativity.

Contribution

It introduces the potential of ngVLA to discover and study pulsars in the Galactic Center, especially those orbiting Sgr A*, which has not been possible before.

Findings

ngVLA will significantly increase pulsar detection in the GC

discovery of a pulsar around Sgr A* could test black hole physics

enhanced understanding of the interstellar medium in the GC

Abstract

Pulsars in the Galactic Center (GC) are important probes of General Relativity, star formation, stellar dynamics, stellar evolution, and the interstellar medium. Despite years of searching, only a handful of pulsars in the central 0.5 deg are known. The high-frequency sensitivity of ngVLA will open a new window for discovery and characterization of pulsars in the GC. A pulsar in orbit around the GC black hole, Sgr A*, will provide an unprecedented probe of black hole physics and General Relativity.
