SN 2019vxm: A luminous and long-lived Type IIn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, T. J. Moriya +38
We present the photometric and spectroscopic analysis of the luminous and long-lasting Type IIn supernova (SN) 2019vxm. The SN reaches a peak V-band absolute magnitude of MV = -20.…
Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…
ENGRAVE follow-up of a type IIb supernova spatially coincident with the sub-threshold gravitational wave trigger S250818k
K. Ackley, M. T. Botticella, A. Boye +54
The candidate gravitational wave (GW) event S250818k was one of only three non-retracted LIGO-Virgo-KAGRA public alerts issued during the fourth observing run of the network (O4) w…
Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions
Claudia P. Gutiérrez, LluÃs Galbany, Joseph P. Anderson +4
Understanding supernova (SN) progenitors remains a major challenge in astrophysics, as it involves untangling the complex interplay between stellar physics (e.g., evolution, binari…
Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Åukasz Wyrzykowski, PrzemysÅaw J. MikoÅajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
Euclid: An automated system to match Rubin transient alerts to Euclid observations
C. Duffy, I. M. Hook, C. M. Gutierrez +150
The Vera C. Rubin observatory is expected to produce 10 million transient alerts per night in ugrizy filters, whilst Euclid is a visible to near-infrared space telescope engaged in…
