Selected chapters on astrophysics (NAST021)

This course is taught in winter semesters and consists of a few independent sub-courses that attempt to provide some insights into the state of the art knowledge in the respective branches of astrophysics or related scientific disciplines. In order to successfully pass the exam, students must complete a set of homework assignments from all of the mandatory sub-courses of the given semester (in maroon below) and present the chosen methods and obtained (correct) results to the examiner (or the whole class) until June 30th of the given academic year. All kinds of information resources are allowed (including consultations with the lecturers and other students). The grade is derived from the degree of correctness of the solutions. Students may enroll to this course repeatedly. In case of any (course related) inquiries, please contact Jaroslav Haas, preferably via email 'haas' (the strange symbol) 'sirrah.troja.mff.cuni.cz'.

Programme of the winter semester 2024/2025

Astronomy at the European Southern Observatory — interferometry

The course aims to offer a view on how the observatories and knowledge base of the European Southern Observatory (ESO) can be used to improve the outcomes and impact of the research projects worked on by the attendees and, in more general terms, what kind of astronomical projects is best suited for the current ESO facilities. In this semester, emphasis will be put on interferometry.

ESO grand scheme and opportunities
Bruno Leibundgut (European Southern Observatory, Garching, Germany)

- when: Friday, October 25th from 10:15; expected duration about 2 hours
- where: TAU (directly at the Astronomical Institute of Charles University)
- slides: 1
- lecture description:

Introductory lecture to the course. The main aim is to describe the basic structure and mission of the European Southern Observatory and its offer of various research opportunities for students as well as professional astronomers. Lively discussions with the lecturer are welcome.

ESO studentship (MEYS): personal experience
Alžběta Oplištilová (Astronomical Institute of Charles University, Prague)

- when: Wednesday, October 30th from 14:00; expected duration about 1 hour
- where: TAU (directly at the Astronomical Institute of Charles University)
- slides: 1
- lecture description:

You will hear about the ESO studentship from the point of view of a PhD student. ESO is a unique place of diversity, where engineers, astronomers, experts from industry and academia, and many other specialists from all over the world cooperate to make very challenging projects possible. ESO is known for its inspiring and supportive community that trains new generations. Come to learn more about ESO studentships, try to apply, and experience being a part of the ESO astronomical community.

The ESO Science Archive: a powerful science resource at your fingertips
Martino Romaniello (European Southern Observatory, Garching, Germany)

- when: Wednesday, November 13th from 14:00; expected duration about 1.5 hours
- where: online only, in Zoom, meeting id 934 5400 7646, password on request
- lecture description:

The ESO Science Archive collects data from over 25 years of observations at the ESO's La Silla Paranal Observatory. This science treasure of tens of millions of files is readily available and accessible at your fingertips, dramatically shortening the time and lowering the effort needed to get to scientific discoveries and publications. In this lecture, I will give an introduction to the main features of the ESO Science Archive, hopefully providing you with the tools to find the data for your own science goals.

The ESO data reduction tools: a Reflex demonstration
Valentin Ivanov (European Southern Observatory, Garching, Germany)

- when & where: together with the lecture of Martino Romaniello (see above)
- lecture description:

The complex ESO science instruments generate complex data and require complex data reduction. To help the scientific exploitation of our data ESO offers tools, called pipelines, to process the data in a easy, but flexible way. I will show how to run these pipelines with Reflex - a graphical environment that automates the data reduction and offers data organization, fast reduction, repeatability and interactivity.

Introduction to optical interferometry: basic concepts, observations, and fitting of geometrical models
Robert Klement (European Southern Observatory, Santiago, Chile)

- when: Wednesday, November 20th from 14:00; Monday, November 25th from 14:00; Wednesday, November 27th from 14:00; expected duration of each session about 1.5 hours
- where: online only, in Zoom, meeting id 970 1065 5196, password on request
- series abstract:

Optical interferometry is an observational technique combining multiple telescopes to achieve the finest possible angular resolution. The state-of-the-art interferometric arrays VLTI (southern hemisphere) and CHARA (northern hemisphere) combine 4 and 6 telescopes, respectively, to routinely achieve an angular resolution of one milliarcsecond (mas) or less in the near-IR. This enables resolving and imaging the surfaces of nearby bright stars, their circumstellar environments, and mapping of close binary orbits, among other science cases. Throughout this short lecture series, I will introduce the basics of interferometry and give an overview of the current capabilities of VLTI and CHARA. This will be followed by practical examples on planning and preparation of observations (using the Aspro and SearchCal tools from JMMC), and a quick overview of data reduction (using dedicated reduction pipelines). Finally, the basics of data analysis will be demonstrated, with a specific focus on fitting of interferometric observables with geometrical models using the Python3 tool PMOIRED (https://github.com/amerand/PMOIRED).

Course keeps evolving. Please keep an eye on this website for updates and/or ask JH.
