MPS-0104398Maura McLaughlinDr. McLaughlin will carry out a program of research as an MPS Distinguished International Postdoctoral Research Fellow at Jodrell Bank Observatory. She will study pulsars, the rapidly rotating, highly magnetized neutron stars which emit pulses that are detected once per rotation. Pulsars have many astrophysical applications, including strong-field gravity, condensed matter physics, particle physics, planetary astronomy, and even cosmology. While pulsars radiate across the entire electromagnetic spectrum, there are over 1100 known radio pulsars and only 40 known X-ray and/or gamma-ray pulsars. Consequently, the relationship between low- and high-energy emission and the emission processes themselves are not well-understood. This research program will lead to a more complete census of the pulsar population, a better understanding of emission mechanisms, and the discovery of unique individual objects. Techniques for discovery will include radio searches for counterparts to high-energy sources and pulsars that are likely to be detectable at high energies, as well as high-energy searches, spectroscopy, and imaging. This research is funded through the Office of Multidisciplinary Activities in the Directorate for Mathematical and Physical Sciences.***

MPS-0104398 Maura McLaughlin博士McLaughlin将在Jodrell Bank天文台担任MPS杰出国际博士后研究员。 她将研究中子星，快速旋转，高度磁化的中子星，每旋转一次就会发出一次脉冲。 脉冲星有许多天体物理学的应用，包括强场引力、凝聚态物理、粒子物理、行星天文学，甚至宇宙学。 虽然射电辐射跨越整个电磁频谱，但已知的射电辐射超过1100种，而已知的X射线和/或伽马射线辐射只有40种。 因此，低能量和高能量发射与发射过程本身之间的关系还没有得到很好的理解。 这项研究计划将导致对脉冲星种群进行更全面的普查，更好地了解发射机制，并发现独特的个体物体。 发现的技术将包括无线电搜索高能量源和可能在高能量下可探测到的辐射源的对应物，以及高能量搜索，光谱学和成像。 这项研究由数学和物理科学局多学科活动办公室资助。
