Dust from refractory r-process elements forms efficiently in kilonova ejecta and explains the observed late-time infrared spectra.
New NIR diagnostic diagrams using [C I]/Paγ and H2 1-0 O(5)/PAH 3.3μm ratios correlate with radiation field hardness and distinguish star formation, AGN, and shock excitation in galaxy nuclei.
Shiva is a new simulation tool that computes time-dependent dust size distributions and band gap energy evolution for HAC grains under photo-processing, sputtering, and shattering in specified interstellar conditions.
