Prerequisites

Basics of Astronomy and Physics is required. It is advised (but not strictly needed) to have followed the course of Observational Techniques. The course of High-Energy Astrophysics is complementary to this course in some specific topics.


Objectives and Contextualisation

Neutron Stars and Black Holes are the extreme leftovers of the explosion of very massive stars. They challenge fundamental aspects of nuclear physics, plasma physics, general relativity, and represent the sources of all detected Gravitational Waves so far, when they are in a binary system and collide. The course is intended to:

  • provide a basic and broad view of the observations and theoretical understanding of Neutron Stars and Black Holes, focusing on their known Galactic population
  • give a self-contained introduction to physics of Gravitational Waves, explaining the current state of detections of compact object mergers, and the beginning of the multi-messenger astronomy era
  • provide an interconnected view of open questions about compact objects, related to the fundamental physics uncertainties and to the observational biases that shape the phenomenology of the detected population

Competences

  • Formulate and tackle problems, both open and more defined, identifying the most relevant principles and using approaches where necessary to reach a solution, which should be presented with an explanation of the suppositions and approaches.
  • Understand the bases of advanced topics selected at the frontier of high energy physics, astrophysics and cosmology and apply them consistently.

Learning Outcomes

  1. Recognise the kind of source that emits radiation in different bands, and know how to estimate the kind of gravitational waves expected from different systems of neutron stars and black holes.
  2. Understand the physical processes responsible for the multi-band emission of neutron stars of different classes, and black holes of various masses.

Content

  • Introduction and observational overview of compact objects in connection with high-energy astronomy
  • Neutron star physics: equation of state
  • Neutron star physics: transport properties
  • Neutron star physics: spin-down of pulsars
  • Neutron star physics: observed emission at different wavelengths and associated physical mechanisms
  • Modeling of the observed population of isolated neutron stars: long-term evolution of magnetic and thermal properties
  • Elements of Special and General Relativity as well as tensor calculus
  • Black holes: basic theory
  • Gravitational waves: basic theory
  • Gravitational waves: post-Newtonian approximation and quantitative study of GW sources
  • Gravitational waves: observational review
  • Binary neutron stars mergers and the new era of the multi-messenger astronomy

Activities and Methodology

Title Hours ECTS Learning Outcomes
Type: Directed      
Lectures 45 1.8 2
Type: Autonomous      
Study of the theoretical and observational concepts 70 2.8 2

Theory lectures, with small exercises in class. Assignment of homework, based on the content seen in class.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.


Assessment

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Homework for different topics 50% 33 1.32 2, 1
Written exam (two chances) 50% 2 0.08 2, 1

The evaluation will be composed of:

  • 50% the average mark of the different assignments given during the course (indicatively one exercise per teacher)
  • 50% one final written exam, with different questions covering the main different topics. There will be a resit exam in case of not reaching the minimum total mark of the course.

This subject does not foresee the single assessment  system.
