Abstract Type Ia supernovae (SNe Ia) play a key role in the fields of astrophysics and
cosmology. It is widely accepted that SNe Ia arise from thermonuclear explosions of white …

Supernovae, the luminous explosions of stars, have been observed since antiquity.
However, various examples of superluminous supernovae (SLSNe; luminosities> 7× 1043 …

We present UV and/or optical observations and models of SN 2023ixf, a type II supernova
(SN) located in Messier 101 at 6.9 Mpc. Early time (flash) spectroscopy of SN 2023ixf …

It is now 16 years since the first data release from the Sloan Digital Sky Survey (SDSS; York
et al. 2000). This Early Data Release, or EDR, occurred in 2001 June (Stoughton et al …

We present a public catalog of transients from the Zwicky Transient Facility (ZTF) Bright
Transient Survey, a magnitude-limited (m< 19 mag in either the g or r filter) survey for …

Most massive stars are members of a binary or a higher-order stellar system, where the
presence of a binary companion can decisively alter their evolution via binary interactions …

We present panchromatic observations and modeling of supernova (SN) 2020tlf, the first
normal Type II-P/L SN with confirmed precursor emission, as detected by the Young …

Abstract We introduce the Automatic Learning for the Rapid Classification of Events
(ALeRCE) broker, an astronomical alert broker designed to provide a rapid and self …

We present ultraviolet/optical/near-infrared observations and modeling of Type II
supernovae (SNe II) whose early time (δt< 2 days) spectra show transient, narrow emission …

ABSTRACT Luminous quasars at> z 5.6 can be studied in detail with the current generation
of telescopes and provide us with unique information on the first gigayear of the universe …
