Resumen
We present the first-year data set of high-cadence, long-duration observations of the bright millisecond pulsar J0437-4715 obtained in the Argentine Institute of Radioastronomy (IAR). Using two single-dish 30 m radio antennas, we gather more than 700 hr of good-quality data with timing precision better than 1 μs. We characterize the white and red timing noise in IAR´s observations, we quantify the effects of scintillation, and we perform single-pulsar searches of continuous gravitational waves, setting constraints in the nHz-μHz frequency range. We demonstrate IAR´s potential for performing pulsar monitoring in the 1.4 GHz radio band for long periods of time with a daily cadence. In particular, we conclude that the ongoing observational campaign of the millisecond pulsar J0437-4715 can contribute to increase the sensitivity of the existing pulsar-timing arrays.
