Absorption spectroscopy
A lecture for the module PHY-755 - Methods of modern Astrophysics.

Find lecture slides and additional material here.

This course will give an overview on data mining and machine learning techniques and their applications in the analysis of current and upcoming large astronomical data sets (e.g. SDSS, Pan-STARRS, DESI, 4MOST, LSST). Addressed topics include (1) classical and Bayesian statistical inference, (2) supervised machine learning for object classification and regression problems, (3) unsupervised machine learning and dimensionality reduction techniques, (4) time series analyis of variable sources.

Zweiter Teil und Fortsetzung des im WS 2020/21 begonnenen Kurses.

Multi-messenger astronomy combines observations of the same astrophysical source obtained by different observational channels, namely, electromagnetic radiation, gravitational waves, neutrinos, and cosmic rays. Each channel tests different astrophysical processes and reveals different information about the sources.
In this course, we will cover known multi-messenger sources: solar flares, supernova explosions, binary neutron star mergers, and blazars. We will focus on the interpretation of the recently detected binary neutron star merger observed as a gravitational wave source (GW170817), a short gramma-ray-burst (GRB170817A), and an electromagnetic kilonova (AT2017gfo). We will discuss the theoretical and experimental background, which is required to understand multi-messenger observations, and we will learn how publicly available software can be used to interpret the observed data.

Contents. Nowadays, the concept of space weather comprises the more active and dynamic phenomena of the general solar-terrestrial relations them. The lecture deals with the question of how the cyclic solar activity affects the earth and the near-earth environment. The focus is on explosive events such as coronal mass ejection and solar flares. Increased flows of charged particles and energetic electromagnetic radiation have a direct impact on manned space travel and satellites but also on technological systems on Earth. In addition to these rather short-term phenomena, the lecture covers also topics on much longer time-scales such as the impact of solar activity on the Earth's climate. Subjects covered in the lecture are: physics of the active Sun, the atmosphere and the magnetosphere of the Earth, the impact of space weather on technical systems, prediction of space weather, solar activity in the context of global climate change, and socioeconomic implications of solar-terrestrial relations.
