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.
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: 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: 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: 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 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: 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: We present cosmological constraints from eight strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar velocity…
