Eva-Maria Ahrer

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

I am also involved in the efforts of the JWST Transiting Exoplanet Community Early Release Science (ERS) team, in particular in the analysis of NIRCam data and in the development of the Eureka! pipelineLink opens in a new window.

Other research interests include stellar activity induced variations in stellar radial velocity (RV) 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 and Dr Vinesh Maguire-Rajpaul.
