Estimating longterm power spectral densities in AGN from simulations
Nachiketa Chakraborty, Frank M. Rieger
The power spectral density (PSD) represents a key property quantifying the stochastic or random noise type fluctuations in variable sources like Active Galactic Nuclei (AGN). In re…
A Framework for Causal Discovery in non-intervenable systems
Peter Jan van Leeuwen, Michael DeCaria, Nachiketa Chakaborty +1
Many frameworks exist to infer cause and effect relations in complex nonlinear systems but a complete theory is lacking. A new framework is presented that is fully nonlinear, provi…
Investigating Multiwavelength Lognormality with Simulations : Case of Mrk 421
Nachiketa Chakraborty
Blazars are highly variable and display complex characteristics. A key characteristic is the flux probability distribution function or flux PDF whose shape depends upon the form of…
