Terahertz Airborne Astronomy using a Four Detector High Resolution Spectrometer: 4GREAT After the Herschel Space Telescope ceased operations in 2013, the astronomical community has been lacking access to those parts of the terahertz spectrum that are not visible from ground-based observatories. The atmosphere blocks most of the radiation at those frequency bands, even at high geographical […]

Deep, Large Scale Surveys of Star Forming Regions throughout the Milky Way   Star formation and the processes involved are not only important to the Milky Way as an astronomical object, but are also crucial to understand our own origin. For instance, only lower-mass stars like our own Sun have supposedly a long enough lifetime to […]

High precision pulsar timing Pulsars are rapidly rotating, highly magnetised neutron stars, remnants of a supernova explosion. The majority of the science that we can do with pulsars comes from a technique that is called pulsar timing. Millisecond pulsars, which are pulsars with spin periods of only few milliseconds, are ideal objects to apply timing since […]

From galaxies to the cosmic web   Astrophysical phenomena occur on a large variety of spatial scales. Although ubiquitous, the interaction between them is often neglected because of the difficulties in their simultaneous modeling. In this talk I will very briefly describe three cases where this interplay is of primary importance, namely: the assembly bias, the […]

PhD colloquium, location: Auditorium 0.02, MPIfR Hans Nguyen GLOSTAR: Investigating Tracers of Early High-Mass Star Formation High-mass stars (>8 msol) are not as numerous as their less massive counterparts but have a much more profound impact on their environment within their native galaxies. Despite their importance, our understanding of their formation process is not as developed […]

PhD colloquium, location: Auditorium 0.02, MPIfR Rohit Dokara Searching for the Ashes of Dead Stars A supernova event marks the death of either a high-mass (>8 Msol) star, or a white dwarf in a binary system. Such an event expels most of the stellar interiors into the surrounding interstellar medium and forms a supernova remnant (SNR). […]

PhD colloquium, location: Seminar room, I. Physikalisches Institut, University of Cologne Hendrik Müller Advanced VLBI Imaging Very Long Baseline Interferometry (VLBI) is an observational technique developed in astronomy for combining multiple radio telescopes into a single virtual instrument with an effective aperture reaching up to many thousand kilometers and enabling measurements at highest angular resolutions. Despite […]
