Quantifying the form-flow-saltation dynamics of aeolian sand ripples
J. M. Nield, M. C. Baddock, G. F. S. Wiggs +9
Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. H…
Visual enhancement and 3D representation for underwater scenes: a review
Guoxi Huang, Haoran Wang, Brett Seymour +4
Underwater visual enhancement (UVE) and underwater 3D reconstruction pose significant challenges in computer vision and AI-based tasks due to complex imaging conditions in aquatic…
Modeling complex species-environment relationships through spatially-varying coefficient occupancy models
Jeffrey W. Doser, Andrew O. Finley, Sarah P. Saunders +3
Occupancy models are frequently used by ecologists to quantify spatial variation in species distributions while accounting for observational biases in the collection of detection-n…
Guidelines for the use of spatially-varying coefficients in species distribution models
Jeffrey W. Doser, Marc Kéry, Sarah P. Saunders +6
Species distribution models (SDMs) are increasingly applied across macroscales. Such models typically assume that a single set of regression coefficients can adequately describe sp…
Changes in night sky brightness after a countywide LED retrofit
Li-Wei Hung, Sharolyn J Anderson, Ashley Pipkin +1
The US National Park Service (NPS) Night Skies Program measured changes in sky brightness resulting from a countywide lighting retrofit project. The retrofit took place in Chelan C…
Dune initiation in a bimodal wind regime
Pauline Delorme, Giles. F. S. Wiggs, Matthew. C. Baddock +3
Early-stage bedforms develop into mature dunes through complex interactions between wind, sand transport and surface topography. Depending on varying environmental and wind conditi…
Integrating automated acoustic vocalization data and point count surveys for estimation of bird abundance
Jeffrey W. Doser, Andrew O. Finley, Aaron S. Weed +1
Monitoring wildlife abundance across space and time is an essential task to study their population dynamics and inform effective management. Acoustic recording units are a promisin…
Gemini Planet Imager Spectroscopy of the Dusty Substellar Companion HD 206893 B
K. Ward-Duong, J. Patience, K. Follette +55
We present new near-infrared Gemini Planet Imager (GPI) spectroscopy of HD 206893 B, a substellar companion orbiting within the debris disk of its F5V star. The , , , and…
Trends in bird abundance differ among protected forests but not bird guilds
Jeffrey W. Doser, Aaron S. Weed, Elise F. Zipkin +2
Improved monitoring and associated inferential tools to efficiently identify declining bird populations, particularly of rare or sparsely distributed species, is key to informed co…
Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager
Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne +49
HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved obs…
HD 165054: an astrometric calibration field for high-contrast imagers in Baade's Window
Meiji M. Nguyen, Robert J. De Rosa, Jason J. Wang +51
We present a study of the HD 165054 astrometric calibration field that has been periodically observed with the Gemini Planet Imager. HD 165054 is a bright star within Baade's Windo…
The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry
Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51
We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
An updated visual orbit of the directly-imaged exoplanet 51 Eridani b and prospects for a dynamical mass measurement with Gaia
Robert J. De Rosa, Eric L. Nielsen, Jason J. Wang +52
We present a revision to the visual orbit of the young, directly-imaged exoplanet 51 Eridani b using four years of observations with the Gemini Planet Imager. The relative astromet…
Revised Astrometric Calibration of the Gemini Planet Imager
Robert J. De Rosa, Meiji M. Nguyen, Jeffrey Chilcote +49
We present a revision to the astrometric calibration of the Gemini Planet Imager (GPI), an instrument designed to achieve the high contrast at small angular separations necessary t…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics From 10-100 AU
Eric L. Nielsen, Robert J. De Rosa, Bruce Macintosh +62
We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey (GPIES). This subsample includes six detected planets and three brown…
