Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic-Ray Processing

The Astrophysical Journal Letters
Spectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO _2 enrichment (CO _2 /H _2 O = 7.6 ± 0.3) that is 4.5 σ above solar system comet trends and among the highest ever recorded.

Photographic Photometry of NGC 6866

Journal of Mathematical and Fundamental Sciences, 2019
. Magnitudes and colors in the UBV photometric system have been determined for 575 stars in and around NGC 6866. The color-color relation of the cluster stars provides an estimate of interstellar reddening of 0.16 mag. The distance of cluster is found to

Connecting Dust and Outflows in Active Galactic Nuclei: The Intriguing Case of NGC 6860

The Astrophysical Journal
Cosmic dust plays a crucial role in the evolution of galaxies, significantly influencing star formation and the interstellar medium. However, in active galactic nuclei (AGNs), the role and origin of dust remain poorly understood.
