CYGNUS+ project: Further development of CYprus models for Galaxies and their Nuclear Spectra
In CYGNUS+ (Further development of CYprus models for Galaxies and their NUclear Spectra) we will develop further the CYGNUS model and the method of SED fitting and use it to fit the panchromatic SEDs of galaxies with excellent photometric and spectroscopic coverage in order to derive physical quantities such as stellar mass, star formation rate, starburst timescale, AGN fraction, dust masses etc.
Additionally, we will further develop the CAFE-NG code based on Marshall et al (2007, 2018) and compare the results of fitting the same set of data with both CYGNUS and CAFE-NG. In particular, we will parallelize two more of our radiative transfer codes, namely the code that calculates the emission of a disk galaxy and the code that calculates the emission of an active galactic nucleus (AGN) torus.
We will then use these codes to generate large grids of models and fit a large sample of galaxies. We also propose to develop further our SED fitting method. The most important development will be the coupling of the MCMC code with a Machine Learning algorithm which will significantly improve the speed of the SED fitting and retrieval of key parameters of the galaxies.
