Star Formation Drives Production of Low Energy Cosmic Rays
Ningyu Tang, Jiahao Liu, Di Li +18
For over a century, the origin of low-energy cosmic rays (LECRs), the dominant heaters and ionizers of dense interstellar gas, remains elusive owing to solar modulation and uncerta…
A tool of Hierarchical cOre ideNtification and Kinematic property AssIgnment (HONKAI) for Dense Cores
Jiawei Liu, Zhiyuan Ren, Di Li +8
Infrared dark clouds (IRDCs) contains cold dense gas at the earliest stage of massive star and cluster formation. In studying the IRDCs, a universal and fundamental task is to reso…
Large scale mapping of [CI] and the [CI]-to-CO transition in Ophiuchus molecular cloud
Jifeng Xia, Ningyu Tang, Thomas G. Bisbas +10
Atomic carbon ([CI]) is a key species in the carbon chemistry of the interstellar medium (ISM). Using the Submillimeter Wave Astronomy Satellite (SWAS), we conducted a [CI](P$_…
