Dust Without Na I D Trace: The Case of Highly Attenuated Type Ib SN 2024vjc
Javier Silva-Farfán, Keiichi Maeda, Andrea Pastorello +19
Understanding dust attenuation toward extragalactic transients is critical for recovering their intrinsic properties and probing the local environments of distant galaxies. A popul…
Querying an astronomical database using large language models: the ALeRCE text-to-SQL system
P. A. Estevez, J. Espejo-Moreira, S. Sanfeliu-Alvarez +10
We develop a text-to-SQL (structured query language) system based on large language models (LLMs) using in-context learning and apply it to the Automatic Learning for the Rapid Cla…
Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an
Ping Chen, Avishay Gal-Yam, Subo Dong +14
We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…
ATLAS100 -- I. A volume-limited sample of supernovae and related transients within 100 Mpc
Shubham Srivastav, Stephen J. Smartt, Thomas Moore +29
We present ATLAS100 -- a sample of 1729 supernovae and other explosive optical transients within Mpc observed by the ATLAS survey over a span of 5.75 years from 2017 Sep…
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…
The SOXS Spectrograph Instrument Control Software
Davide Ricci, Bernardo Salasnich, Andrea Baruffolo +51
SOXS (Son Of X-Shooter) is a new spectrograph for the European Southern Observatory (ESO), recently installed at the New Technology Telescope (NTT) at the La Silla Observatory, Chi…
