Michaela Ďuríšková & Ema Šipková: Erasmus Internships: What, Why and How?

Erasmus+ is a program that supports traineeships, work placements and internships abroad for students of Bachelor and Master studies enrolled in a Higher Education Institutions. In this short talk, we would like to introduce the program, tell you about the opportunities it provides, and offer tips and tricks about the process of successfully finding internship opportunities and applying for them. Afterward, we would like to tell you about our own projects carried out as a part of Erasmus+ internships.

Ema Šipková – The impact of P-T profile on exoplanet transmission spectroscopy

The launch of the James Webb Space Telescope provides a unique opportunity to characterize atmospheres around both Jupiter-like giants and Earth-like rocky planets. One of the most prolific methods for exoplanet atmospheric observations is the technique of transmission spectroscopy. The transmission spectra of a planet is shaped by the chemical composition of the atmosphere, the presence of clouds and hazes, which are linked to the pressure-temperature profile of an atmosphere.

The goal of this Erasmus+ project is to understand the impact of pressure-temperature profiles on the observed transmission spectra of exoplanets. To achieve this we will apply an open-source atmospheric model (TauREx).

Michaela Ďuríšková – High energy transient sources to investigate the quantum gravity vacuum dispersion

Gamma-Ray-Bursts (GRBs) are intense, short, and unrepeatable flashes of radiation. GRB prompt emission is observable in an extensive energy band, making these sources perfect candidates to study quantum gravity vacuum dispersion of the light. The traineeship aims to study the dependence of delays between different energy bands’ light curves as a function of the cosmological distance. The higher the redshift, the higher the delay between different energy bands’ light curves should be. HERMES-SP team is developing innovative techniques to accurately estimate delays and related errors. We want to apply this novel temporal analysis to a sample of GRB with known redshifts to obtain a constraint on the quantum gravity realm.
