1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Elias Önerud; [2023]
   Keywords : Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

   Abstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

3. 2. Quality Assessment of the Fabry-Pérot Wavelength Calibration for CRIRES+ : Student Project Report

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Christopher Borchert; [2023]
   Keywords : ;

   Abstract : The data reduction software of CRIRES+, a new high-resolution spectrometer installed at VLT, features a calibration routine that uses data from a Fabry-Pérot étalon. The quality of this calibration mode is assessed in this project report. READ MORE

4. 3. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Chinmaya Nagar; [2023]
   Keywords : Emission-line ratio; Gaussian convolution; Green pea galaxies; ISM; Ionised ISM; Lyman continuum LyC ; Low-Redshift Lyman Continuum Survey LzLCS ; Lyman continuum emitter LCE ; LyC escape; LyC escape fraction; MUSE; MPDAF; Voronoi binning;

   Abstract : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

5. 4. Simulations of the Tenuous Upper Atmospheres of Exoplanets

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Lucian Spitzner; [2023]
   Keywords : astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

   Abstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

6. 5. Planning Observations of Terrestrial ExoplanetsAround M Type Stars with CRIRES+

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Jonas Zbinden; [2021]
   Keywords : ;

   Abstract : In recent decades, thousands of exoplanets have been discovered. The next step is to characterize theobserved planets in terms of their radii, masses, density, physical conditions and composition of theiratmospheres. READ MORE
