Tristan studies the structure of the Milky Way. His work primarily focuses on star clusters, which trace the large-scale morphology of our Galaxy and its spiral pattern, but also retain clues about the conditions of star formation. He is an active member of the Gaia Data Analysis and Processing Consortium, and the spectroscopic surveys WEAVE and 4MOST.
 

Nadiia Pulatova works on the project "The Sources of Excitation of the Optical Emission in X-ray Selected Galaxies" within the Walter Benjamin Programme of the Deutsche Forschungsgemeinschaft (the German Research Foundation).  She uses data from the SDSS-V, XMM-Newton and eROSITA to determine the properties of X-ray galaxies, such as the excitation mechanisms in the optic and to estimate the masses of supermassive black holes. In her research she focuses on local galaxies (z < 0.4). Her scientific interests include: Extragalactic astronomy  (in particular, active galactic nuclei (AGN), X-ray and optical  spectroscopy, supermassive black holes, reprocessing mechanisms, morphology of the galaxies).

My main interest is massive binary stars. From their orbital properties to their complex evolution. To understand the conecction between these two aspects, I work with spectroscopic surveys of massive stars, characterising their orbital and physical properties, and trying to uncover interesting systems in different evolutionary phases that can helps us to understand the effects of binarity in the life and death of these massive objects.

Eleonora is interested in mapping the structure and the star formation properties of the young Milky Way, using both massive OB-type stars and lower-mass pre-main sequence stars. She mainly works with data from the Gaia satellite, and she is currently involved in the OB-star target selection of the SDSS-V survey.

Based on high-resolution, multi-epoch spectroscopy, Johanna is working to characterize binary star systems with compact companions. She is interested in uncovering the formation pathways of these systems and, more broadly, constraining the properties of the black hole population in the Milky Way.

Rhys is interested in exploring the landscape of dormant stellar mass black holes in binaries in the Milky Way. In particular, he uses spectroscopic disentangling techniques to help reveal stellar companions “hiding” in the spectra of spatially unresolved binaries and constrain the parameters of the system and both components. For this, he uses multi-epoch high-resolution spectra from instruments such as the FEROS spectrograph at La Silla Observatory. Outside of research he likes to engage in outreach and activism, to share his love for Astronomy with people from all walks of life.

Irina works with Bernd Husemann on the CARS project: www.cars-survey.org. She compares different star formation tracers to figure out how AGN affects its host galaxy.
