拉萨地块是研究班公湖—怒江特提斯洋和雅鲁藏布江特提斯洋演化过程的关键,但印度—亚洲大陆的碰撞可能导致拉萨地块遭受不同程度的重磁化影响,为寻找理想地层进行古地磁研究,本文对拉萨地块中二叠世洛巴堆组砂岩、火山岩及灰岩样品进行详细的岩石磁学研究,以确定各类岩石是否具备记录原生剩磁信息的能力.结果表明砂岩样品中主要载磁矿物为磁黄铁矿,火山岩及灰岩样品中主要为磁铁矿或赤铁矿.结合区域地质资料和部分样品退磁实验,本文认为砂岩样品可能遭受林子宗群火山和岩浆活动所提供的区域热扰动影响,记录了古近系重磁化信息;火山岩和灰岩样品可能记录了岩石形成时期的原生剩磁信息,有望从中获得可靠古地磁数据.

The Water Cherenkov Detector Array(WCDA) is a major component of the Large High Altitude Air Shower Array Observatory(LHAASO), a new generation cosmic-ray experiment with unprecedented sensitivity, currently under construction. WCDA is aimed at the study of TeV γ-rays. In order to evaluate the prospects of searching for TeV γ-ray sources with WCDA, we present a projection of the one-year sensitivity of WCDA to TeV γ-ray sources from TeVCat using an all-sky approach. Out of 128 TeVCat sources observable by WCDA up to a zenith angle of 45°, we estimate that 42 would be detectable in one year of observations at a median energy of 1 TeV. Most of them are Galactic sources, and the extragalactic sources are Active Galactic Nuclei(AGN).

天琴计划预期于2035年左右发射并部署边长约17万公里的等边三角形卫星星座,构成一个引力波天文台—天琴。天琴将对10^(-4)~1 Hz频段的引力波进行探测,为人类描绘一幅更全面的宇宙图景。在本文中,我们对天琴计划的背景和提出过程、天琴的主要探测对象和主要科学目标、天琴需要攻克的核心关键技术问题、天琴计划技术路线图及进展等进行介绍,以方便更多人加入这一项富有挑战而又激动人心的工作。
