WFST Supernovae in the First Year: III. Systematical Study of the Photometric Behavior of Early-phase Core-collapse Supernovae

Junhan Zhao, Ji-an Jiang, Zelin Xu +22

We investigate the multiband photometric properties of seven supernovae (SNe) showing double-peaked light-curve evolution and prominent shock-cooling emission, observed by the Wide…

WFST Supernovae in the First Year: II. SN 2024aedt: Systematical Study of a Transitional Type Ia Supernova

Dezheng Meng, Ji-an Jiang, Xu Kong +26

We present comprehensive photometric and spectroscopic observations of a transitional type Ia SN 2024aedt, discovered by the 2.5-meter Wide Field Survey Telescope (WFST) within one…

WFST Supernovae in the First Year: I. Statistical Study of 16 Early-phase Type Ia Supernovae from the Pilot Survey

Weiyu Wu, Ji-an Jiang, Zelin Xu +27

In this paper we present 16 early-phase type Ia supernovae (SNe Ia) discovered during the pilot survey of the 2.5-meter Wide Field Survey Telescope (WFST-PS) from March 4 to July 1…

A Common Origin of Normal Type Ia Supernovae Suggested by the Photometric Diversity

Weiyu Wu, Ji-an Jiang, Dezheng Meng +16

In recent years, with an increasing number of type Ia supernovae (SNe Ia) discovered soon after their explosions, a non-negligible fraction of SNe Ia with early-excess emissions (E…

Photometric Redshifts with the LSST: Evaluating Survey Observing Strategies

Melissa L. Graham, Andrew J. Connolly, Željko Ivezić +5

In this paper we present and characterize a nearest-neighbors color-matching photometric redshift estimator that features a direct relationship between the precision and accuracy o…
