SN 2023uqf: An Interacting Supernova Coincident with a High-Energy Neutrino

Robert Stein, Anna Y. Q. Ho, Anjasha Gangopadhyay +30

Astrophysical high-energy (TeV-PeV) neutrinos were first discovered in 2013, but their origin remains largely unknown. Here we present SN 2023uqf, a supernova found in coincidence…

The La Silla Schmidt Southern Survey

Adam A. Miller, Natasha S. Abrams, Greg Aldering +75

We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics…

ZTF SN Ia DR2: Environmental dependencies of stretch and luminosity of a volume limited sample of 1,000 Type Ia Supernovae

M. Ginolin, M. Rigault, M. Smith +43

To get distances, Type Ia Supernovae magnitudes are corrected for their correlation with lightcurve width and colour. Here we investigate how this standardisation is affected by th…

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…

Candidate strongly lensed type Ia supernovae in the Zwicky Transient Facility archive

A. Townsend, J. Nordin, A. Sagués Carracedo +61

Gravitationally lensed type Ia supernovae (glSNe Ia) are unique astronomical tools that can be used to study cosmological parameters, distributions of dark matter, the astrophysics…

ZTF SN Ia DR2: The diversity and relative rates of the thermonuclear SN population

G. Dimitriadis, U. Burgaz, M. Deckers +28

The Zwicky Transient Facility SN Ia Data Release 2 (ZTF SN Ia DR2) contains more than 3,000 Type Ia supernovae (SNe Ia), providing the largest homogeneous low-redshift sample of SN…
