Eva-Maria Ahrer

I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick, supervised by Prof Peter Wheatley. I am currently working on low-resolution transmission spectroscopy data of exoplanet atmospheres obtained with the EFOSC2 instrument at the New Technology Telescope (NTT) which is located at La Silla, Chile. In particular, I am looking at features in the atmospheres of hot Jupiters such as Na absorption or Rayleigh scattering in the optical wavelength range.

Other research interests include activity induced variations in stellar radial velocity data and their effects on accurate estimation of exoplanet characteristics. This also includes Bayesian model comparison with the nested sampling algorithm PolyChord. This follows my work during my research based Masters degree at the University of Cambridge under supervision of Prof Didier Queloz.
