Travel Time Shifts due to Amplitude Modulation in Time-Distance Helioseismology
R. Nigam, A. G. Kosovichev
Correct interpretation of acoustic travel times measured by time-distance helioseismology is essential to get an accurate understanding of the solar properties that are inferred fr…

Analytical models for Cross-correlation signal in Time-Distance Helioseismology
R. Nigam, A. G. Kosovichev, P. H. Scherrer
In time-distance helioseismology, the time signals (Doppler shifts) at two points on the solar surface, separated by a fixed angular distance are cross-correlated, and this leads t…

Simulations of Oscillation Modes of the Solar Convection Zone
D. Georgobiani, A. G. Kosovichev, R. Nigam +2
We use the three-dimensional hydrodynamic code of Stein and Nordlund to realistically simulate the upper layers of the solar convection zone in order to study physical characterist…
