Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations
Corentin Ravoux, Bastien Carreres, Julian Bautista +60
Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…
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 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 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…
Searching for core-collapse supernovae in binaries with ZTF
Sylvia J. Zhu, Jakob Nordin, Emma de Oña-Wilhelmi +1
Context. Stripped envelope supernovae occur in massive stars that have lost their outer layers before exploding, possibly from binary interactions. Recently, SN 2022jli was detecte…
Discovery of SN 2025wny: a Strongly Gravitationally Lensed Superluminous Supernova at z = 2.01
Joel Johansson, Daniel A. Perley, Ariel Goobar +31
We present the discovery of SN 2025wny (ZTF25abnjznp/GOTO25gtq) and spectroscopic classification of this event as the first gravitationally lensed Type I superluminous supernovae (…
AMPEL workflows for LSST: Modular and reproducible real-time photometric classification
Jakob Nordin, Valery Brinnel, Jakob van Santen +2
Modern time-domain astronomical surveys produce high throughput data streams which require tools for processing and analysis. This will be critical for programs making full use of…
Flaires: A Comprehensive Catalog of Dust-Echo-like Infrared Flares
Jannis Necker, Eleni Graikou, Marek Kowalski +5
Context: Observations of transient emission from extreme accretion events onto supermassive black holes can reveal conditions in the center of galaxies and the black hole itself. M…
SNGuess: A method for the selection of young extragalactic transients
N. Miranda, J. C. Freytag, J. Nordin +7
With a rapidly rising number of transients detected in astronomy, classification methods based on machine learning are increasingly being employed. Their goals are typically to obt…
Establishing accretion flares from massive black holes as a source of high-energy neutrinos
Sjoert van Velzen, Robert Stein, Marat Gilfanov +26
The origin of cosmic high-energy neutrinos remains largely unexplained. For high-energy neutrino alerts from IceCube, a coincidence with time-variable emission has been seen for th…
