10 Abril 2026, 10:00 • Israel Matute Troncoso

The topics addressed in this lecture were:

  1. Basic description of the lambda-CDM cosmological model
  2. The different evolutionary phases of the Universe
  3. The importance of the Epoch of Reionization (EoR) Phase
  4. Photon production vs recombination
  5. Sources of Reionization: SF vs AGN vs others
  6. Feedback processes in the EoR
  7. The Lyman continuum leakage and ionizing photon escape fraction
  8. Observational probes of Re-ionization

Introduction to Galaxies (III) - Kinematics (II)

In this lecture, we explored the following concept related to kinematics in Spiral & Elliptical galaxies:

  • The Tully-Fisher relation: Importance, Uncertainties & Implications
  • Kinematics: Elliptical galaxies
  • DM content in Elliptical galaxies
  • Scaling-relation: Faber-Jackson & Fundamental plane
  • The origin of the flattening in Elliptical galaxies

Presentation/Discussion of general topics in Extragalactic Astrophysics

3 Março 2026, 17:30 • Israel Matute Troncoso

Each student presented over 5 minutes one of the topics proposed in the previous TP (see list below). The presentation was followed by a short group discussion. The topics presented and discussed wre:

  • 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 (III) - Kinematics (I)

3 Março 2026, 16:30 • Israel Matute Troncoso

The following topicsrelated to morphological and kinematic classification of galaxies were presented and discussed in this lecture:

  • Morphological classification, i.e. decomposing light profiles
  • Quantifying morphology: Sérsic Index, CAS, Gini, M20, EGG, …
  • Kinematics
  • Measuring rotation: spectroscopy
  • Discovery of Dark Matter
  • First Scaling-relation: Tully-Fisher

Introduction to Galaxies (II)

27 Fevereiro 2026, 10:00 • Israel Matute Troncoso

This lecture discussed topics related to the "Classification, Morphology & Structural Parameters" of galaxies. Among the topics discussed, we included:

  • Magnitude definition
  • The Distance Scale
  • Qualitative Classifications  of Galaxies
  • Hubble Sequence 
  • De Vaucouleurs
  • Main characteristics - Elliptical, Lenticular, Spirals, Irr.
