A High-Frequency Search for Pulsars Within the Central Parsec of SgrA*

Macquart, J-P., Kanekar, N., Frail, D. et al.

Understand

We report results from a deep high-frequency search for pulsars within the central parsec of Sgr A* using the Green Bank Telescope.

The observing frequency of 15 GHz was chosen to maximize the likelihood of detecting normal pulsars (i.e.
with periods of $\sim 500$\,ms and spectral indices of $\sim -1.7$) close to Sgr A*, that might be used as probes of gravity in the strong-field regime; this is the highest frequency used for such pulsar searches of the Galactic Center to date.
No convincing candidate was detected in the survey, with a $10\sigma$ detection threshold of $\sim 10 \mu$Jy achieved in two separate observing sessions.
