Kavli Affiliate: Renxin Xu | Summary:Long-period radio transients (LPTs) are a newly discovered class of radio emitters with periods ranging from minutes to hours. The astrophysical nature remains undetermined, particularly of LPTs with no detectable companions. We report the first evidence for a plausible supernova remnant (SNR) association with an LPT (DART J1832-0911, 2656.23+-0.15 s […]

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 […]
