Tails and Trails: Comets and NEOs Survive Co-addition in Rubin Early Data Preview 2

Colin Orion Chandler, Joseph Murtagh, Ian Chow +11

We identify effectively single-visit imaging hidden within the deep co-added images of the NSF-DOE Vera C. Rubin Observatory Early Data Preview 2 (EDP2). These shallow regions cont…

SN 2024afyu interpreted as a Pair Instability Supernova

P. J. Pessi, S. Barmentloo, Ł. Wyrzykowski +63

Pair-instability supernovae (PISNe) are the predicted explosions of very massive stars triggered by electron-positron pair production. Numerous transients have been proposed as PIS…

Multi-year Ground-Based Survey Photometry of Active Comet 103P/Hartley 2 and Centaur (2060) Chiron: A Tale of Two Comets in the Pre-LSST Era

Joseph Murtagh, Megan E. Schwamb, Michael S. P. Kelley +22

Comets and Centaurs trace the evolution of trans-Neptunian objects (TNOs) into the inner solar system. Their activity reflects the interplay between volatile sublimation, dust dyna…

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…

On the Border: Searching for Cometary Activity Near the Centaur-JFC Transition Line

A. Fraser Gillan, Alan Fitzsimmons, Colin Orion Chandler +2

Current wide-field surveys discover ~15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover man…

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-…

Dust production rates in Jupiter-family comets II: Trends and population insights from ATLAS photometry of 116 JFCs

A. Fraser Gillan, Alan Fitzsimmons, Larry Denneau +4

Jupiter-family comets (JFCs) have orbital periods of less than 20 years and therefore undergo more frequent sublimation compared to other comet populations. The JFCs therefore repr…

Quasi-periodic X-ray eruptions years after a nearby tidal disruption event

M. Nicholl, D. R. Pasham, A. Mummery +61

Quasi-periodic Eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems i…

Dust production rates in Jupiter-family Comets: A two-year study with ATLAS photometry

A. Fraser Gillan, Alan Fitzsimmons, Larry Denneau +4

Jupiter-family Comets (JFCs) exhibit a wide range of activity levels and mass-loss over their orbits. We analyzed high-cadence observations of 42 active JFCs with the wide-field As…
