Speaker: Hannah Zohren Title: Galaxy Clusters – Optical Confirmation and Weak Lensing Mass Constraints Abstract: Samples of galaxy clusters provide a versatile basis for studies of the cosmological parameters that govern the Universe. They are assembled based on observable properties of the clusters. Detections based on the Sunyaev Zel’dovich (SZ) effect build the basis for surveys […]

Speaker: Prajwal Padmanabh (chair: Yuxin Lin) Title: Long term profile stability of J1022+1001 Abstract: Understanding pulsar profile instability is key to placing accurate limits on the detectability of gravitational waves with pulsar timing arrays. The profile stability of PSR J1022+1001 is investigated. Data from the Effelsberg Pulsar Observation System (EPOS) which operated in the 1990s and […]

Speaker: Ivana Beslic , Chair: Vishnu Balakrishnan Title: ISM in molecular phase at high resolution: Molecular Clouds, Star Formation and Dense Gas at Arcsecond-Scale Across NGC 3627 Abstract: We present new NOrthern Extended Millimeter Array (NOEMA) observations towards a nearby (~11Mpc), large (Mmolecular~1010.5M_sun), actively star-forming (SFR~2M_sun yr-1) disc Galaxy – NGC3627. These observations currently represent the […]

IMPRS talk by Hannah Zohren, Chair: Ivana Title: Galaxy Clusters – Weak Lensing Mass Constraints Galaxy clusters provide a versatile basis for studies of the cosmological parameters that govern the Universe. Detections based on the Sunyaev Zel’dovich (SZ) effect allow us to find clusters at very high redshift. These enable astrophysical and cosmological investigations that can […]

Speaker: Joscha Jahns, Chair: Hannah Zohren Title: Fast Radio Bursts Abstract: Fast radio bursts (FRBs) are an enigmatic new class of radio transients. They are very bright but only a few milliseconds long and come from galaxies at ~Gpc distance. Although there have been about a hundred observed by now, their origin is still unknown. In […]
