Expanding general topics related to Extragalactic Astrophysics

24 Fevereiro 2026, 17:30 Israel Matute Troncoso

Expanding knowledge on general topics related to the course. During the TP class and at home, the students had to investigate the listed topics below and prepare a short 5 minute presentation for the next TP class. The topics proposed were:

  • Integral Field Spectroscopy (IFS)
  • Imaging Surveys
  • Spectroscopic Surveys
  • Machine Learning in Astrophysics
  • Cosmological Simulations
  • Tools to model the SED of galaxies (CIGALE + others)
  • Stellar classification (the H-R diagram)
  • K-correction
  • ΔE linked to redshifted photons - Where does it go?


Introduction to Galaxies (I)

This lecture introduced key conceot and ideas necessary for the course. Among the topics discussed, we list:

  • What do we know about the Universe?
  • Observations vs Theory
  • Where is the information coming from?
  • Observations: counting photons - Flux & Luminosity
  • Photometry & Spectroscopy: what do they measure?
  • Cosmological model assumptions
  • Cosmological Redshift
  • What is a galaxy?


Overview of the course

The students were introduced to the main objectives of the course and its assessment:

  • Primary Goal: Provide an advanced understanding of astrophysical phenomena beyond the Milky Way.
  • Approach: Integrates observational data, theoretical models, and computational approaches.
  • Prerequisites: Prior knowledge of stellar astrophysics, cosmology basics, and general relativity.
  • Assessment: Assignments, final project presentation and report, and exam 
  • Final Project Focus: Data analysis from surveys or simulations
