The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases

A. Fiore, A. Kozyreva, L. Yan +40

Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…

Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. III: Hunting for electron-capture supernovae using nebular spectroscopy

Kaustav K. Das, Anders Jerkstrand, Mansi M. Kasliwal +18

Electron-capture supernovae (ECSNe) may arise from ONeMg-core collapse in super-asymptotic giant branch (sAGB) stars near the low-mass core-collapse limit (--\,\Msu…

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) at $…

Photometric classification of supernovae detected by the Zwicky Transient Facility using noise augmentation

A. Townsend, J. Nordin, M. Kowalski +27

Modern time-domain surveys, such as the Zwicky Transient Facility (ZTF), detect far more extragalactic transients than can be spectroscopically classified. Photometric classificati…

Study of the anisotropy of cosmic expansion on ZTF type Iasupernovae simulations

C. Barjou-Delayre, P. Rosnet, C. Ravoux +29

The cosmological principle assumes the isotropy of the Universe at large scales. It is a foundational assumption in the CDM model, which is the current standard model of cosmol…

QZO: A Catalog of 5 Million Quasars from the Zwicky Transient Facility

S. J. Nakoneczny, M. J. Graham, D. Stern +11

Machine learning methods are well established in the classification of quasars (QSOs). However, the advent of light curve observations adds a great amount of complexity to the prob…
