My main research interests are (click for more details):
In my specific research context, strong gravitational lensing gives us a chance to observe some low-mass galaxies that would be invisible without the strong lensing magnification. Our group has discovered two strong galaxy-galaxy lenses in which the background source is an EELG at z > 1: Brammer et al. (2012) and van der Wel et al. (2013). I am using the gain in spatial resolution due to the lens shear as well as the magnification to study spatial variations in interstellar medium properties with MUSE, as well as with ALMA (PI: da Cunha) and X-Shooter (PI: Amorín).Using MUSE, I study the restframe-ultraviolet spectra of high-redshift galaxies. Features in this part of the spectrum, such as the C III] and Lyman-alpha emission lines, provide a lot of information about the physical state of these young galaxies. This type of study is extremly powerful when combined with information from the restframe-optical region, which can be obtained with Hubble's WFC3 camera. A key strength to this approach is the un-targeted nature of both instruments, allowing us to get a clear view of the full population of galaxies.
