RR Lyrae stars as tracers of substruc­ture and Galac­tic archaeology

Zdenek Prudil - Hector Fellow Eva Grebel

Galactic archaeology uses stars as fossils to study the evolutionary history of galaxies like our own Milky Way. Cosmological simulations suggest that larger galaxies were partially formed by accreting smaller dwarf galaxies. Such merger events should leave observable signatures in the form of star streams, but empirical constraints on the times, numbers, and importance of such mergers are still missing.

Towards Topolog­i­cal Many-Body Physics Using State-Depen­dent Optical Lattices

Hendrik von Raven – Hector Fellow Immanuel Bloch

In modern condensed matter physics topology plays a fundamental role in the classification of phases of matter. A prominent example is the quantum Hall effect discovered in two-dimensional electron gases under extreme conditions. Quantum Hall insulators are isolating in the bulk, but exhibit conducting edge states, which results in a quantised Hall conductance.

Accom­mo­da­tion Behav­ior and Ciliary Muscle Activ­ity in Myopia

Sandra Wagner – Hector Fellow Eberhart Zrenner

Prevalence of myopia (shortsightedness) increases considerably in industrialized countries. The mechanisms behind this development need to be fully understood in order to arrive at prevention. The aim of Sandra Wagner’s research was to allow a better understanding of accommodation, address unanswered question regarding myopia onset and support the development of new devices.

Mechan­i­cal manip­u­la­tion of molec­u­lar spins in CNT resonators

Tim Althuon – Hector Fellow Wolfgang Wernsdorfer

Carbon nanotube (CNT) resonators will be designed and fabricated to exploit their sensing properties. We will graft a single-molecule magnet (SMM) on such a CNT resonator in order to manipulate its spin states via the mechanical motion of the CNT. Using this nanomechanical approach, single-molecule magnets will be investigated with the long-term prospect of applying them in future quantum technologies.

Tempo­ral and spatial micro­bial dynam­ics in the Arctic Ocean

Magda Cardozo-Miño – Hector Fellow Antje Boetius

The project investigates composition and function of microbial communities in Fram Strait, the major gateway between the Arctic and the Atlantic Oceans, and how these are linked with environmental conditions. A series of cutting-edge, molecular approaches are applied to assess microbial functional capacities, community composition and their temporal variation in a region under special threat by climate change. The project is supervised by Hector Fellow Antje Boetius.

Unveil­ing the Galac­tic History with Pulsat­ing Variable Stars

Gustavo Medina Toledo – Hector Fellow Eva Grebel

This project aims to explore the use of young and old pulsating variable stars to improve our current understanding of the Milky Way. This will be achieved by performing a novel study of the kinematics, ages and chemical compositions of Cepheids and RR Lyrae stars which, in spite of being archetypes of different stellar populations, represent key tracers of the recent star formation and assembly history of the Galaxy.

Sensi­tive period plastic­ity and functional recov­ery after sight restoration

Rashi Pant - Hector Fellow Brigitte Röder

Visual experience during a sensitive period is crucial for the normal development of the brain. Individuals who are treated for congenital cataracts more than a few weeks from birth suffer from low visual acuity as well as specific deficits (such as impaired face processing). This project investigates the possible mechanisms that mediate this sensitive period, by non-invasively assessing brain structure and function in congenitally and developmentally visually deprived individuals.
