SN 2025coe: A Multiple-Peaked Calcium-Strong Transient from A White-Dwarf Progenitor
Chun Chen, Ning-Chen Sun, Qiang Xi +25
SN 2025coe is a calcium-strong transient located at an extremely large projected offset 39.3 kpc from the center of its host, the nearby early-type galaxy NGC 3277 at a dista…
SN 2021lwz: Another Exotic Luminous and Fast Evolving Optical Stripped Envelope Supernova ?
F. Poidevin, S. L. West, C. M. B. Omand +25
Current large-scale, high-cadence surveys, such as the ZTF, provide detections of new and rare types of transients and supernovae whose physical origins are not well understood. We…
Witnessing the violent, merger-driven formation of an extremely massive galaxy 1.7 Gyr after the Big Bang
Lura K. Pitchford, Joseph Cairns, Duncan Farrah +4
We combine near-infrared imaging in two bands from the Hubble Space Telescope (HST) with archival observations of molecular gas to study SDSS J160705.16+533558.6 (J1607), an extrem…
SN 2024aecx: a fast-evolving Type IIb supernova with a prominent shock-cooling peak
Qiang Xi, Ning-Chen Sun, David Aguado +36
SN 2024aecx is a nearby (11 Mpc) Type IIb SN discovered within 1 d after explosion. In this paper we report high-cadence photometric (typically 0.51 day) and spec…
An extreme proto-cluster of luminous dusty starbursts in the early Universe
I. Oteo, R. J. Ivison, L. Dunne +17
We report the identification of an extreme proto-cluster of galaxies in the early Universe whose core (nicknamed Distant Red Core, DRC) is formed by at least ten dusty star-forming…
