Topic: transients

Join the High-Energy Astrophysics group led by Kirpal Nandra to study galaxy clusters and cosmology, active galactic nuclei, accreting compact objects, transients or hot diffuse gas. Research draws on major X-ray programmes including eROSITA and Einstein Probe. The three-year positions are available immediately and are paid according to TVöD, up to E14 depending on qualifications.

The University of São Paulo's High Energy and Plasma Astrophysics group seeks a postdoctoral fellow to develop realistic simulations and reconstruction pipelines for double-layer water Cherenkov detector designs for the Southern Wide-field Gamma-ray Observatory. The researcher will quantify detector performance and develop the joint SWGO-CTAO science case for transients, diffuse emission, cosmic-ray anisotropy and multi-TeV sources, with planned visits to the Max Planck Institute for Nuclear Physics and the SWGO site.

Very Long Baseline Interferometry (VLBI) provides milliarcsecond scale angular resolution imaging. This proves suitable to monitor structural evolution on AU scales in our Galaxy and on parsec scales in extragalactic sources. Given the high brightness temperatures required for detection on such small angular scales, VLBI observations are typically focused on non-thermal sources like relativistic jets and shocked emission regions in the environment of compact sources. I will present a few selected results over various mass scales, including novae, such as 2021 RS Oph and the upcoming T CrB out
