Towards Automated Satellite Conjunction Management with Bayesian Deep Learning
Francesco Pinto, Giacomo Acciarini, Sascha Metz +7
After decades of space travel, low Earth orbit is a junkyard of discarded rocket bodies, dead satellites, and millions of pieces of debris from collisions and explosions. Objects i…
Spacecraft Collision Risk Assessment with Probabilistic Programming
Giacomo Acciarini, Francesco Pinto, Sascha Metz +7
Over 34,000 objects bigger than 10 cm in length are known to orbit Earth. Among them, only a small percentage are active satellites, while the rest of the population is made of dea…
Image processing for precise geometry determination
Ines Belgacem, Grégory Jonniaux, Frédéric Schmidt
Reliable spatial information can be difficult to obtain in planetary remote sensing applications because of errors present in the metadata of images taken with space probes. We hav…
Radiation Damage Study of SensL J-Series Silicon Photomultipliers Using 101.4 MeV Protons
Alexei Ulyanov, David Murphy, Joseph Mangan +6
Radiation damage of J-series silicon photomultipliers (SiPMs) has been studied in the context of using these photodetectors in future space-borne scintillation detectors. Several S…
Planck intermediate results. LVII. Joint Planck LFI and HFI data processing
Planck Collaboration, Y. Akrami, K. J. Andersen +136
We present the NPIPE processing pipeline, which produces calibrated frequency maps in temperature and polarization from data from the Planck Low Frequency Instrument (LFI) and High…
Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes
M. Martinelli, C. J. A. P. Martins, S. Nesseris +82
In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-du…
