Center for Astrophysics Research and Technologies Seminar Series
Pulsar Studies and their Applications
Presented by Pratik Kumar (UNM)
Pulsars are rapidly rotating neutron stars with varied applications in different areas of Physics. One of these included detecting low-frequency gravitational waves via Pulsar Timing Arrays (PTAs) by accurately timing a set of high precision pulsars. Constraining the background noise due to other sources is essential for this effort. One of the largest sources of error for PTAs is the time variable effects of the interstellar medium and the Solar Wind. Since low-frequency radio observations of pulsars are most sensitive to these variations, they can test and improve the existing models used in PTAs and solar wind studies. I will talk about the recent work we have been doing towards testing the efficacy of these solar wind models and implications for PTAs, using the long-term pulsar monitoring data of the Long Wavelength Array. For the second part of the talk, I will discuss the ongoing work using X-ray and radio observations to study the bow-shock pulsar wind nebula of PSR J0002+6216.
