Validation of Fast Mocks Generation for CSST Photometric Survey
Weak lensing has become a powerful tool for probing the matter distribution in the Universe and constraining cosmological parameters. This paper aims to explore the fast mock generation pipeline to obtain the covariance matrix of the $3\times 2$pt analysis for the upcoming China Space Station Telescope (CSST). We adopt the $N_\mathrm{side}$ pipeline, which generates matter distribution with lognormal assumptions, to create full-sky galaxy mocks with certain two-point statistics. We also employ …

Auftakt zum #GreenCulture Festival auf Zollverein in Essen mit einem Workshop zur Müllvermeidung bei Kulturveranstaltungen mit Jonas Gudegast.

Mann in einem hellblauen Hemd und schwarzen Hosen steht in einem modernen Büro und präsentiert an einer Flipchart.

The board is partially set up with stones placed on it, and there are additional stones in small piles beside the board. The table is situated on a wooden deck, with a stool visible to the right. **Chinese:** 一张黑白照片，展示了一个围棋棋盘在户外的小圆桌上摆放。棋盘上部分摆放了棋子，旁边有额外的棋子堆放。桌子位于一个木质平台上，右侧可见一个凳子。
Lucky SHD 400 **English:** A black and white photograph of a street scene featuring a cart filled with cleaning tools and supplies. The cart includes brooms, dustpans, and bags, suggesting it is used for street cleaning or maintenance. The background is slightly blurred, showing a street with buildings and columns. **Chinese:** 一张黑白照片，展示了街道场景，其中有一辆装满清洁工具和用品的手推车。手推车上有扫帚、簸箕和袋子，表明它用于街道清洁或维护。背景稍微模糊，显示了一条有建筑和柱子的街道。
Lucky SHD 400 **English:** A black and white photograph taken inside a public transportation vehicle, likely a bus or tram. The interior is filled with passengers, some seated and some standing. The scene is slightly blurred, capturing the motion and activity within the vehicle. A sign at the front reads "We are arriving." **Chinese:** 一张黑白照片，拍摄于公共交通工具内部，可能是公交车或有轨电车。车内乘客众多，有些坐着，有些站着。场景稍微模糊，捕捉了车内的运动和活动。前方有一个标志写着“We are arriving (我们即将到达）”。
