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…
Illuminating the Local Universe: Large-Scale Structure from ZTF Type Ia Supernovae
Antoine Gilles Lordet, Ariel Goobar, Jens Jasche +12
Within the volume-limited subsample at of the Zwicky Transient Facility (ZTF) DR2 sample, we confirm a statistically significant excess of Type Ia supernovae (SNe Ia) arou…
A Natural Telescope: Discovery of the Strongly Lensed Type II SN 2025mkn at
Cameron Lemon, Ariel Goobar, Joel Johansson +90
We present the discovery of SN 2025mkn, a gravitationally lensed Type II supernova. First detected as a blue transient in ZTF, 0.83 from a elliptical gala…
ZTF SN Ia DR2: Overview
Mickael Rigault, Mathew Smith, Ariel Goobar +53
We present the first homogeneous release of several thousand Type Ia supernovae (SNe Ia), all having spectroscopic classification, and spectroscopic redshifts for half the sample.…
ZTF SN~Ia DR2: Cosmology-independent constraints on Type Ia supernova standardisation from supernova siblings
S. Dhawan, E. Mortsell, J. Johansson +18
Understanding Type Ia supernovae (SNe~Ia) and the empirical standardisation relations that make them excellent distance indicators is vital to improving cosmological constraints. S…
ZTF SN Ia DR2: Study of Type Ia Supernova lightcurve fits
M. Rigault, M. Smith, N. Regnault +34
Type Ia supernova (SN Ia) cosmology relies on the estimation of lightcurve parameters to derive precision distances that leads to the estimation of cosmological parameters. The emp…
ZTF SN Ia DR2: Colour standardisation of Type Ia Supernovae and its dependence on environment
M. Ginolin, M. Rigault, Y. Copin +37
As type Ia supernova (SN Ia) cosmology transitions from a statistics-dominated to a systematics-dominated era, it is crucial to understand the remaining unexplained uncertainties t…
ZTF SN Ia DR2: Impact of the galaxy cluster environment on the stretch distribution of Type Ia supernovae
F. Ruppin, M. Rigault, M. Ginolin +28
Understanding the impact of the astrophysical environment on Type Ia supernova (SN Ia) properties is crucial to minimize systematic uncertainties in cosmological analyses based on…
ZTF SN Ia DR2: Peculiar velocities impact on the Hubble diagram
B. Carreres, D. Rosselli, J. E. Bautista +35
SNe Ia are used to determine the distance-redshift relation and build the Hubble diagram. Neglecting their host-galaxy peculiar velocities (PVs) may bias the measurement of cosmolo…
Growth-rate measurement with type-Ia supernovae using ZTF survey simulations
Bastien Carreres, Julian E. Bautista, Fabrice Feinstein +21
Measurements of the growth rate of structures at with peculiar velocity surveys have the potential of testing the validity of general relativity on cosmic scales. In this…
