Stress-testing the spatially flat Universe: nonparametric spatial curvature determination from DESI DR2
Hannah C. Turner, Suhail Dhawan, Sunny Vagnozzi +2
We present a nonparametric determination of spatial curvature using only late-time geometrical probes. Under a Gaussian Process smoothness prior, we jointly constrain the dimension…
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 III: Spectroscopic Time-delay Measurements of a Strongly Gravitationally Lensed Superluminous Supernova
Joel Johansson, Edvard Mörtsell, Ariel Goobar +30
We present spatially resolved spectra and infer the time-delays between the multiple images of the strongly gravitationally lensed superluminous supernova (SLSN) 2025wny at z=2.015…
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…
BlackTHUNDER -- A non-stellar Balmer break in a black hole-dominated little red dot at
Xihan Ji, Roberto Maiolino, Hannah Übler +34
Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called ``Little Red Dots'' (LRDs) at , many of wh…
Two-dimensional kinematics and dynamical modelling of the 'Jackpot' gravitational lens from deep MUSE observations
Hannah C. Turner, Russell J. Smith, Thomas E. Collett
We present results from the first spatially resolved kinematic and dynamical modelling analysis of the unique SDSSJ0946+1006 ('Jackpot') triple-source lens system, where a single m…
Gravitational imaging through a triple source plane lens: revisiting the CDM-defying dark subhalo in SDSSJ0946+1006
Daniel J. Ballard, Wolfgang J. R. Enzi, Thomas E. Collett +2
The CDM paradigm successfully explains the large-scale structure of the Universe, but is less well constrained on sub-galactic scales. Gravitational lens modelling has been used…
