RUI: Studies of Gravitation, the Interstellar Medium, and Pulsars

RUI：引力，星际介质和脉冲星的研究。 韦斯伯格博士将继续在三个领域进行调查。 （一） 第一颗脉冲双星的相对论引力研究： 对这颗脉冲星的持续观测将用于 引力辐射发射、大地自转、地球自转 岁差，G的恒定性，以及对替代方案的限制， 广义相对论 (2)脉冲星的测量与分析 距离和星际介质; 21厘米-脉冲星吸收 将测量光谱。 这些数据将用于研究脉冲星 距离和中性氢和自由电子分布 和银河系的密度。 (3)脉冲星偏振测量和定时 调查：偏振和定时测量将在120 在阿雷西博天文台每隔三个月观测一次。 的 这些观测结果将用于脉冲星的研究 发射机制、脉冲形态、毛刺、定时噪声，以及 旋进;并通过法拉第旋转测量，调查 银河系磁场。 该奖项是根据 研究在本科院校（RUI）在NSF的活动。

RUI: Studies of Gravitation, the Interstellar Medium, and Pulsars. Dr. Weisberg will continue investigations in three areas. (1) Studies of relativistic gravitation with the first binary pulsar: Continued observations of this pulsar will be used for investigation of gravitational radiation emission, geodetic spin precession, the constancy of G, and constraints on alternatives to general relativity. (2) Measurements and analyses of pulsar distances and the interstellar medium; 21-cm--pulsar absorption spectra will be measured. These data will be used to study pulsar distances and the neutral hydrogen and free electron distribution and density in the Galaxy. (3) A pulsar polarimetry and timing survey: Polarization and timing measurements will be made on 120 pulsars at three-month intervals at the Arecibo Observatory. The output of these observations will be used for studies of pulsar emission mechanisms, pulse morphology, glitches, timing noise, and precession; and, via Faraday rotation measurements, investigations of the galactic magnetic field. This award is made under the Research in Undergraduate Institutions (RUI) activity at the NSF.
