Very Large Telescope observations of interstellar comet 3I/ATLAS III: High-resolution monitoring of CN and forbidden oxygen emission across the perihelion passage with ESPRESSO

Baltasar Luco, Thomas H. Puzia, Rohan Rahatgaonkar +2

We characterize in 3I/ATLAS the heliocentric evolution of the CN production rate and the forbidden [OI] emission, describe the broader emission line inventory, and release the anal…

Tidal pre-conditioning and ram-pressure stripping in NGC 1427A. Deep VLT/MUSE spectroscopy and FUV-to-radio observations trace a Fornax Cluster dwarf in transformation

J. P. Carvajal, T. H. Puzia, M. Blaña +11

The early environmental transformation of low-mass cluster galaxies from gas-rich to gas-poor remains poorly constrained, partly because clear, phase-resolved observations are rare…

The complex history of NGC 1427A revealed by its star clusters and star formation history

Katja Fahrion, Michael Hilker, Avinash Chaturvedi +2

Star-forming low-mass galaxies in the dense environments of galaxy clusters provide opportunities to study how environmental effects such as ram-pressure stripping, tidal interacti…

Pre-perihelion evolution of the NiI/FeI abundance ratio in the coma of the interstellar comet 3I/ATLAS. From extreme to normal

Damien Hutsemékers, Jean Manfroid, Emmanuël Jehin +9

Emission lines of FeI and NiI are commonly found in the coma of Solar System comets, even at large heliocentric distances. These atoms are most likely released from the surface of…

Spectral Characteristics of Interstellar Object 3I/ATLAS from SOAR Observations

Thomas H. Puzia, Rohan Rahatgaonkar, Juan Pablo Carvajal +2

Interstellar objects (ISOs) provide unique insights into the building blocks and conditions of extrasolar planetary systems. The newly discovered object, 3I/ATLAS (C/2025 N1), repr…

Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances*

Rohan Rahatgaonkar, Juan Pablo Carvajal, Thomas H. Puzia +25

We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025~N1) from to ~au using X-shooter (300--550\,nm, ) and UVES (opt…

NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)

Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305

We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…

Tuning into spatial frequency space: Satellite and space debris detection in the ZTF alert stream

J. P. Carvajal, F. E. Bauer, I. Reyes-Jainaga +6

A significant challenge in the study of transient astrophysical phenomena is the identification of bogus events, among which human-made satellites and debris in Earth orbit remain…
