Introducing : a new universal kinematic disturbance parameter
Jonah M. Powley, Rebecca J. Smethurst, Chris J. Lintott +1
We introduce a new kinematic disturbance parameter, (pronounced `DVSG'), which takes advantage of integral field spectroscopy (IFS) to quantify differences between…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario JuriÄ +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-…
The effects of bar strength and kinematics on galaxy evolution II: The global and local impacts of slow-strong bars
Petra Mengistu, Karen L. Masters, Tobias Geron +3
There is now clear evidence, from a variety of studies, that galactic bars contribute to and/or accelerate processes which quench galaxies. However, bars have a variety of strength…
Technosignature Searches of Interstellar Objects
James R. A. Davenport, Sofia Z. Sheikh, Steve Croft +17
With the discovery of the third confirmed interstellar object (ISO), 3I/ATLAS, we have entered a new phase in the exploration of these long-predicted objects. Though confirmed disc…
From a Different Star: 3I/ATLAS in the context of the Åtautahi-Oxford interstellar object population model
Matthew J. Hopkins, Rosemary C. Dorsey, John C. Forbes +3
The discovery of the third interstellar object (ISO), 3I/ATLAS (`3I'), provides a rare chance to directly observe a small body from another Solar System. Studying its chemistry and…
The visibility of the Åtautahi-Oxford interstellar object population model in LSST
Rosemary C. Dorsey, Matthew J. Hopkins, Michele T. Bannister +4
With a new probabilistic technique for sampling interstellar object (ISO) orbits with high efficiency, we assess the observability of ISOs under a realistic cadence for the upcomin…
