Saying Hallo to M94's Stellar Halo: Investigating the Accretion History of the Largest Pseudobulge Host in the Local Universe
Katya Gozman, Eric F. Bell, Adam Smercina +7
It is not yet settled how the combination of secular processes and merging gives rise to the bulges and pseudobulges of galaxies. The nearby ( 4.2 Mpc) disk galaxy M94 (NGC…
Science-Driven Optimization of the LSST Observing Strategy
LSST Science Collaboration, Phil Marshall, Timo Anguita +102
The Large Synoptic Survey Telescope is designed to provide an unprecedented optical imaging dataset that will support investigations of our Solar System, Galaxy and Universe, acros…
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-…
Characterizing dw1335-29, a recently discovered dwarf satellite of M83
Andreia Carrillo, Eric Bell, Jeremy Bailin +4
The number, distribution, and properties of dwarf satellites are crucial probes of the physics of galaxy formation at low masses and the response of satellite galaxies to the tidal…
An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Removing Internal Reflections from Deep Imaging Datasets
Colin Slater, Paul Harding, Chris Mihos
We present a means of characterizing and removing internal reflections between the CCD and other optical surfaces in an astronomical camera. The stellar reflections appear as out-o…
