Follow-up of SN 2025wny V: Lens Modelling and Cosmography of a Strongly Lensed Superluminous Supernova at using Space Data
Edvard Mörtsell, Joel Johansson, Ariel Goobar +12
We present a lensing and cosmographic analysis of the strongly lensed Type I superluminous supernova SN 2025wny at redshift , multiply imaged by two foreground galaxies at…
Follow-up of SN 2025wny IV: Photometric Time-delay Measurements of a Strongly Lensed Superluminous Supernova
Alice Townsend, Suhail Dhawan, Erin E. Hayes +34
We present photometric time-delay measurements of SN 2025wny, the first strongly lensed Type I superluminous supernova (SLSN-I), discovered at . Time-delay measurements…
Follow-up of SN 2025wny II: Superluminous Supernova Physics at Cosmic Noon
Maggie L. Li, Lin Yan, Anamaria Gkini +46
SN 2025wny is a gravitationally lensed, hydrogen-poor superluminous supernova (SLSN-I) at z = 2.015. To date, it is the most extensively observed high-redshift core-collapse SN and…
Follow-up of SN 2025wny I: Space-based Observations of the First Multiply-imaged Superluminous Supernova
Ariel Goobar, Joel Johansson, Edvard Mörtsell +21
We present space-based follow-up observations of the superluminous Type I supernova (SLSN-I) SN 2025wny at redshift , gravitationally lensed by two galaxies at redsh…
skysurvey: a pure python package to simulate the transient sky
M. Rigault, M. Ginolin, L. Dellazzeri +12
Accurate simulation of astronomical observations is a critical element for any modern analyses, be it to measure event rates, analyses population properties, validate or train pipe…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
