An improved periodic activation for PINNs reconstructing convective flows
Michael Mommert, Marie-Christine Volk, Christian Bauer
Architectures with periodic activation functions have already been shown to be beneficial in comparison to monotonic counterparts for a wide range of applications of physics-inform…
Probing the Taxonomic Diversity of the Small Near-Earth Object Population
Andy J. López-Oquendo, David E. Trilling, Michael Mommert +1
Small near-Earth objects (NEOs) represent the immediate source population of meteors and meteorites and provide a direct window into the compositional and dynamical evolution of th…
NEO Colors from The Mission Accessible Near-Earth Object Survey (MANOS)
Nicholas Moskovitz, Theodore Kareta, Samantha Hemmelgarn +13
We present spectro-photometric griz colors for 189 near-Earth objects (NEOs) collected by the Mission Accessible Near-Earth Object Survey (MANOS). Data acquisition involved non-sim…
An Efficient Shift-and-Stack Algorithm Applied to Detection Catalogs
Steven Stetzler, Mario Jurić, Pedro H. Bernardinelli +22
The boundary of solar system object discovery lies in detecting its faintest members. However, their discovery in detection catalogs from imaging surveys is fundamentally limited b…
Temperature and pressure reconstruction in turbulent Rayleigh-Bénard convection by Lagrangian velocities using PINN
R. Barta, M. -C. Volk, C. Bauer +2
Velocity, pressure, and temperature are the key variables for understanding thermal convection, and measuring them all is a complex task. In this paper, we demonstrate a method to…
A PINN Methodology for Temperature Field Reconstruction in the PIV Measurement Plane: Case of Rayleigh-Bénard Convection
Marie-Christine Volk, Anne Sergent, Didier Lucor +3
We present a method to infer temperature fields from stereo particle-image velocimetry (PIV) data in turbulent Rayleigh-Bénard convection (RBC) using Physics-informed neural networ…
Curvature-based energy spectra revealing flow regime changes in Rayleigh-Bénard convection
Michael Mommert, Philipp Bahavar, Robin Barta +3
We use the local curvature derived from velocity vector fields or particle tracks as a surrogate for structure size to compute curvature-based energy spectra. An application to hom…
The DECam Ecliptic Exploration Project (DEEP). VII. The Strengths of Three Superfast Rotating Main-belt Asteroids from a Preliminary Search of DEEP Data
Ryder Strauss, Andrew McNeill, David E. Trilling +19
Superfast rotators (SFRs) are small solar system objects that rotate faster than generally possible for a cohesionless rubble pile. Their rotational characteristics allow us to mak…
Design and Performance of the Upgraded Mid-InfraRed Spectrometer and Imager (MIRSI) on the NASA Infrared Telescope Facility
Joseph L. Hora, David E. Trilling, Andy J. Lopez-Oquendo +12
We describe the new design and current performance of the Mid-InfraRed Spectrometer and Imager (MIRSI) on the NASA Infrared Telescope Facility (IRTF). The system has been converted…
Periodically activated physics-informed neural networks for assimilation tasks for three-dimensional Rayleigh-Bénard convection
Michael Mommert, Robin Barta, Christian Bauer +2
We apply physics-informed neural networks to three-dimensional Rayleigh-Bénard convection in a cubic cell with a Rayleigh number of Ra = 10^6 and a Prandtl number of Pr = 0.7 to as…
The DECam Ecliptic Exploration Project (DEEP) II. Observational Strategy and Design
Chadwick A. Trujillo, Cesar Fuentes, David W. Gerdes +19
We present the DECam Ecliptic Exploration Project (DEEP) survey strategy including observing cadence for orbit determination, exposure times, field pointings and filter choices. Th…
The DECam Ecliptic Exploration Project (DEEP) VI: first multi-year observations of trans-Neptunian objects
Hayden Smotherman, Pedro H. Bernardinelli, Stephen K. N. Portillo +25
We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project (DEEP). Of these 110 TNOs, 105 do n…

Pedro H. Bernardinelli, Hayden Smotherman, Zachary Langford +24
We present a detailed study of the observational biases of the DECam Ecliptic Exploration Project's (DEEP) B1 data release and survey simulation software that enables direct statis…
"TNOs are Cool": A survey of the trans-Neptunian region X. Analysis of classical Kuiper belt objects from Herschel and Spitzer observations
E. Vilenius, C. Kiss, T. Müller +14
The classical Kuiper belt contains objects both from a low-inclination, presumably primordial, distribution and from a high-inclination dynamically excited population. Based on a s…

S. Fornasier, E. Lellouch, T. Müller +17
Transneptunian objects (TNOs) are bodies populating the Kuiper Belt and they are believed to retain the most pristine and least altered material of the solar system. The Herschel O…
