Linear toroidal-inertial waves on a differentially rotating sphere with application to helioseismology: Modeling, forward and inverse problems
Tram Thi Ngoc Nguyen, Damien Fournier, Laurent Gizon +1
This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on…

The extended adjoint state and nonlinearity in correlation-based passive imaging
Tram Thi Ngoc Nguyen
This articles investigates physics-based passive imaging problem, wherein one infers an unknown medium using ambient noise and correlation of the noise signal. We develop a general…

Inferring solar differential rotation and viscosity via passive imaging with inertial waves
Tram Thi Ngoc Nguyen, Thorsten Hohage, Damien Fournier +1
The recent discovery of inertial waves on the surface of the Sun offers new possibilities to learn about the solar interior. These waves are long-lived with a period on the order o…
