Kavli Affiliate: Ke Wang | First 5 Authors: Chen Tan, Ke Wang, , , | Summary: According to the Schr"odinger-Poisson equations, fuzzy dark matter (FDM) can form a stable equilibrium configuration, the so-called FDM soliton. In principle, given the FDM particle mass, the profile of FDM soliton is fixed. In practice, however, there is a […]

Kavli Affiliate: Xian Chen | First 5 Authors: Peng Peng, Alessia Franchini, Matteo Bonetti, Alberto Sesana, Xian Chen | Summary: Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs) are important gravitational wave (GW) sources for the Laser Interferometer Space Antenna (LISA). It has been recently suggested that EMRIs and IMRIs can both form in the accretion […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Di Li, Mao Yuan, Lin Wu, Jingye Yan, Xuning Lv | Summary: Long-period radio transients (LPTs) are a newly discovered class of radio emitters with yet incomprehensibly long rotation periods, ranging from minutes to hours. The astrophysical nature of their isolated counterparts remains undetermined. We report a […]

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: Let $X:={X(t)}_{tge0}$ be a generalized fractional Brownian motion: $$ {X(t)}_{tge0}overset{d}{=}left{ int_{mathbb R} left((t-u)_+^{alpha}-(-u)_+^{alpha} right) |u|^{-gamma/2} B(du) right}_{tge0}, $$ with parameters $gamma in (0, 1)$ and $alphain left(-1/2+ gamma/2, , 1/2+ gamma/2 right)$. This is a self-similar Gaussian process introduced […]
