SpecCal: Ambiguity-Aware Candidate Calibration for Infrared Spectrum-Based Molecular Structure Reconstruction
Yixuan Chen, Bo Liu, Yusen Tan +3
The paper presents SpecCal, a training‑free, model‑agnostic framework that re‑ranks and augments candidate molecules to improve reconstruction of molecular structures from infrared…
JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
Data Fusion and Contrastive Alignment for Unconstrained IR Molecular Structure Elucidation
Ethan J. Mick, Campbell A. Sweet, Matthias J. Young +1
The paper introduces a modified encoder‑decoder transformer with a Mixture‑of‑Experts decoder and contrastive alignment loss to predict full molecular structures directly from infr…
Update on the Magellan InfraRed Multi-Object Spectrograph (MIRMOS)
Maren Cosens, Nicholas P. Konidaris, Gwen C. Rudie +21
The paper describes the design of MIRMOS, a new infrared multi‑object and integral‑field spectrograph for the 6.5 m Magellan telescopes, detailing its wavelength coverage, slit‑mas…
SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA): Atmospheric and Fundamental Parameters of Ultracool Dwarfs
Zhijun Tu, Shu Wang, Haomiao Huang +2
The paper presents the SPHEREx Ultracool Dwarf spectrophotometric Atlas (SUDA), a homogeneous dataset of 1675 field ultracool dwarfs with continuous 0.75–5 µm spectra, and derives…
