Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM

A. Fraser Gillan, Łukasz Wyrzykowski, Przemysław J. Mikołajczyk +69

Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…

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…

Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum

Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19

The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…

Investigating APOKASC Red Giant Stars with Abnormal Carbon to Nitrogen Ratios

Erica Bufanda, Jamie Tayar, Daniel Huber +2

The success of galactic archaeology and the reconstruction of the formation history of our galaxy critically relies on precise ages for large populations of stars. For evolved star…

TNO or Comet? The Search for Activity and Characterization of Distant Object 418993 (2009 MS9)

Erica Bufanda, Karen J. Meech, Jan T. Kleyna +10

2009 MS9 is a trans-Neptunian object (TNO) whose perihelion brings it close to the distance where some long period comets are seen to become active. Knowing this, and the fact that…

Interstellar Object Accessibility and Mission Design

Benjamin P. S. Donitz, Declan Mages, Hiroyasu Tsukamoto +6

Interstellar objects (ISOs) represent a compelling and under-explored category of celestial bodies, providing physical laboratories to understand the formation of our solar system…

Characterizing the Manx Candidate A/2018 V3

Caroline Piro, Karen J. Meech, Erica Bufanda +10

Manx objects approach the inner solar system on long-period comet (LPC) orbits with the consequent high inbound velocities, but unlike comets, Manxes display very little to no acti…

The Evolution of Active Galactic Nuclei in Clusters of Galaxies from the Dark Energy Survey

E. Bufanda, D. Hollowood, T. E. Jeltema +53

The correlation between active galactic nuclei (AGN) and environment provides important clues to AGN fueling and the relationship of black hole growth to galaxy evolution. In this…
