Combining Direct Black Hole Mass Measurements and Spatially Resolved Stellar Kinematics to Calibrate the - Relation of Active Galaxies
Nico Winkel, Vardha N. Bennert, Raymond P. Remigio +8
The origin of the tight scaling relation between the mass of supermassive black holes (SMBHs; ) and their host-galaxy properties remains unclear. Active galactic nuclei…
J1721+8842: The first Einstein zig-zag lens
F. Dux, M. Millon, C. Lemon +16
We report the discovery of the first example of an Einstein zig-zag lens, an extremely rare lensing configuration. In this system, J1721+8842, six images of the same background qua…
Turbocharging constraints on dark matter substructure through a synthesis of strong lensing flux ratios and extended lensed arcs
Daniel Gilman, Simon Birrer, Anna Nierenberg +1
Strong gravitational lensing provides a purely gravitational means to infer properties of dark matter halos and thereby constrain the particle nature of dark matter. Strong lenses…
Breaking the mass-sheet degeneracy in strong lensing mass modeling with weak lensing observations
Narayan Khadka, Simon Birrer, Alexie Leauthaud +1
The Hubble constant (), a crucial parameter in cosmology, quantifies the expansion rate of the universe so its precise measurement is important to understand the fundamental d…
JWST Photometric Time-Delay and Magnification Measurements for the Triply-Imaged Type Ia "Supernova H0pe" at z = 1.78
J. D. R. Pierel, B. L. Frye, M. Pascale +60
Supernova (SN) H0pe is a gravitationally lensed, triply-imaged, Type Ia SN (SN Ia) discovered in James Webb Space Telescope imaging of the PLCK G165.7+67.0 cluster of galaxies. Wel…
LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
J. D. R. Pierel, N. Arendse, S. Ertl +39
Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…
