Prof. Suyu misst die Expansionsrate unseres Universums, erforscht die Natur der dunklen Energie, untersucht die Entstehung/Entwicklung von Galaxien und deren Halos aus dunkler Materie und beobachtet Supernovae durch Gravitationslinsen. Sie leitete das H0LiCOW-Programm (www.h0licow.org), mit dem die Entfernungen zu sechs Gravitationslinsen gemessen und der starke Gravitationslinseneffekt als eine der besten kosmologischen Sonden etabliert wurden. Außerdem leitet sie das HOLISMOKES-Programm (www.holismokes.org) zur Untersuchung der Kosmologie und der Vorläufersterne von Supernovae mit Hilfe von Gravitationslinsen.
Astronomy and Astrophysics
Abstract: Combining deep Hubble Space Telescope (HST) images and extensive data from the Multi-Unit Spectroscopic Explorer, we present new mass models of the cluster MACS J1149.5+2223, strongly lensing the…
Astronomy and Astrophysics
Abstract: Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise constraint on the…
Astronomy and Astrophysics
Abstract: Strong gravitationally lensed supernovae (LSNe), though rare, are exceptionally valuable probes for cosmology and astrophysics. Upcoming time-domain surveys such as the Vera Rubin Observatory’s Legacy…
Astronomy and Astrophysics
Abstract: We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak observatories confirms…
Astronomy and Astrophysics
Abstract: We present a search for strong gravitational lenses in Euclid imaging with a high stellar velocity dispersion (σv > 180 km s−1) reported by SDSS and DESI. We performed expert visual inspection and…
Science
Abstract: Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolution of these…
Astronomy and Astrophysics
Abstract: Time-delay cosmography leverages strongly lensed quasars to measure the Universe's current expansion rate, H0, independently from other methods. The latest TDCOSMO milestone measurement primarily used…
Astrophysical Journal
Abstract: Strongly lensed supernovae (SNe) are a rare class of transient that can offer tight cosmological constraints that are complementary to methods from other astronomical events. We present a follow-up…
Astronomy and Astrophysics
Abstract: Strongly lensed quasars provide valuable insights into the rate of cosmic expansion, the distribution of dark matter in foreground deflectors, and the characteristics of quasar hosts. However,…
Astrophysical Journal
Abstract: Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter w and the matter…
