Prof. Suyu is measuring the expansion rate of our Universe, probing the nature of dark energy, studying the formation/evolution of galaxies and their dark matter halos, and observing supernovae through gravitational lensing. She has led the H0LiCOW program (www.h0licow.org) that measured the distances to six gravitational lenses, establishing strong lensing as one of the best cosmological probes. She is also leading the HOLISMOKES program (www.holismokes.org) to study cosmology and supernova progenitors with lensed supernovae.

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: 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…
Astronomy and Astrophysics
Abstract: We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope and…
Astronomy and Astrophysics
Abstract: We used strong gravitational lensing to study the mass distribution of the galaxy cluster MACS J0035.4a 2015, by modeling its total mass distribution. The combination of high-resolution imaging from…
Astronomy and Astrophysics
Abstract: We present a comprehensive spectroscopic analysis of MACS J0138-2155, at z = 0:336. It is the first galaxy cluster known to host two strongly lensed supernovae (SNe), Requiem and Encore, and thus…
Astronomy and Astrophysics
Abstract: The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class…
Astronomy and Astrophysics
Abstract: We investigated the ability of the Euclid telescope to detect galaxy-scale gravitational lenses. To do so, we performed a systematic visual inspection of the 0.7 deg2 Euclid Early Release Observations…
Astronomy and Astrophysics
Abstract: The Euclid Wide Survey (EWS) is predicted to find approximately 170 000 galaxy-galaxy strong lenses from its lifetime observation of 14 000 deg2 of the sky. Detecting this many lenses by visual…
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,…
