Preprocessing celestial spectra is crucial for accurate automated classification. This study introduces a new theoretical model and methods for spectrum flux standardization, outperforming conventional approaches for galaxies and quasars.

Area of Science:

  • Astronomy and Astrophysics
  • Data Science

Context:

  • Automated classification of celestial spectra requires preprocessing to mitigate noise and flux variations.
  • Existing methods for spectrum flux standardization may not be optimal.

Purpose:

  • To develop and evaluate a theoretical model and novel methods for celestial spectrum flux standardization.
  • To compare the proposed methods against conventional techniques.

Summary:

  • The study proposes a theoretical model for celestial spectra flux and introduces several standardization methods.
  • Experiments on normal galaxies (NGs) and quasi-stellar objects (QSOs) demonstrate the effectiveness of the proposed methods, showing they outperform conventional approaches.
  • The research analyzes, compares, and evaluates these methods theoretically.
