Towards precision astrometry of scattered images of compact radio sources: scintillometry theory and prospects
Dylan L. Jow, Delon Shen
Compact radio sources such as pulsars and FRBs undergo scintillation in the interstellar medium (ISM) when scattered images interfere at the observer. ``Scintillometry'' refers to…

Direct correlation of line intensity mapping and CMB lensing from evolution along the lightcone
Delon Shen, Nickolas Kokron, Emmanuel Schaan
Line intensity mapping (LIM) promises to probe previously inaccessible corners of the faint and high-redshift universe. However, confusion with bright foregrounds is a major challe…
