(in Polish) Astrofizyka dżetów 7404-ASTROJET

Full description:

Topics discussed during the lecture:

- description and characteristics of radiation of astrophysical objects in which jets are observed, in particular discussion of: active galactic nuclei, microquasars, gamma-ray bursts, pulsar nebulae, young stellar objects and planetary nebulae,

- effects related to the subluminal motion of jet components,

- processes responsible for energy recovery from rotating black holes (Penrose, Blandford-Znajek processes, etc.),

- study of particle acceleration processes based on analysis of jet radiation,

- characteristics of physical processes responsible for jet radiation,

- simple model of emission in the case of a homogeneous jet fragment,

- model of emission of a conical, inhomogeneous jet.

Total student workload

1. Hours with the teacher's participation are 30 hours of lecture. 2. Time spent on individual work: 30 hours to consolidate and expand knowledge, based on the proposed sources. 3. Time required to prepare for the final exam is 30 hours. 4. Internships are not planned.

Learning outcomes - knowledge

After completing this course, the student: - is able to list and characterise all astrophysical sources in which jets are generated (K_W06), - knows the specific effects observed in the radiation of a given type of source and is able to explain what causes them (K_W06), - knows how to describe the basic physical processes occurring in jets (K_W02, K_W05), - knows the basic assumptions of astrophysical models used to describe jet radiation, (K_W07)

Learning outcomes - skills

After completing this course, the student: - is able to mathematically describe all the most important physical processes that are observed in astrophysical jets (K_U01, K_U02), - is able to prepare and present a popular science paper on a selected type of source in which jets occur (K_U08) - is able to undertake further exploration of knowledge about astrophysical jets based on professional scientific papers (K_U09)

Learning outcomes - social competencies

After completing this course, the student: - knows the limitations of their own knowledge but knows where to get more information on a selected topic (K_K01) - is able to formulate their own opinions on the results of current and past scientific research and is able to justify these opinions appropriately (K_K04), - has the ability to explain phenomena discussed during the lecture to a person who has only basic knowledge of mathematics, physics and astronomy (K_K04)

Expository teaching methods

- problem-based lecture

Exploratory teaching methods

- classic problem-solving

Prerequisites

Basic astronomical knowledge is required, in particular knowledge of radio astronomy, visible light research, and high-energy observations. Additionally, basic knowledge of general relativity and knowledge of the types and properties of elementary particles are required.

Assessment criteria

The lecture is graded on the basis of one final written exam. During the exam, three of the topics presented during the lecture must be discussed. These topics may be descriptive or enumerative in nature, where it will be necessary to present/derive a mathematical description of a given physical phenomenon. The topics are scored in terms of difficulty, a positive assessment requires at least 50% of the total number of points.
