The Case for Space: Estimating Precise Time Delays from Ground- and Space-Based Observations of Lensed Supernovae with Glimpse
Erin E. Hayes, Suhail Dhawan, Stephen Thorp +2
The delay in arrival time of the multiple images of gravitationally lensed supernovae (glSNe) can be related to the present-day expansion rate of the universe, . Despite the…
The impact of ultraviolet suppression on the rates and properties of strongly lensed Type IIn supernovae detected by LSST
Andrés I. Ponte Pérez, Graham P. Smith, Matt Nicholl +4
Upcoming wide-field time-domain surveys, such as the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) are expected to discover up to two orders of magnitude more…
Challenges and Opportunities for time-delay cosmography with multi-messenger gravitational lensing
Simon Birrer, Graham P. Smith, Anowar J. Shajib +2
Strong gravitational lensing of variable sources, such as quasars or supernovae, can be used to constrain cosmological parameters through a technique known as "time-delay cosmograp…
Microlensing of lensed supernovae Zwicky & iPTF16geu: constraints on the lens galaxy mass slope and dark compact object fraction
Nikki Arendse, Edvard Mörtsell, Luke Weisenbach +9
To date, only two strongly lensed type Ia supernovae (SNIa) have been discovered with an isolated galaxy acting as the lens: iPTF16geu and SN Zwicky. The observed image fluxes for…
