Pulsar scattering as a probe for structures in the interstellar medium
Qiuyi He, Xun Shi, Guangxing Li
Due to the inhomogeneity of electron number density, radio waves emitted by pulsars undergo scattering as they pass through the interstellar medium (ISM). However, a connection bet…

Modification to the Jeans criterion by external tides: Anisotropic fragmentation and formation of filaments
Guang-Xing Li
The Jeans criterion sets the foundation of our understanding of gravitational collapse. Jog studied the fragmentation of gas under external tides and derived a dispersion relation…

Transport-driven super-Jeans fragmentation in dynamical star-forming regions
Guang-Xing Li
The Jeans criterion is one cornerstone in our understanding of gravitational fragmentation. A critical limitation of the Jeans criterion is that the background density is assumed t…
