Evaluation of the performance of a CdZnTe-based soft γ -ray detector for CubeSat payloads
Parker, Quentin A.; Ritter, Andreas; Pal, Partha Sarathi +4 more
The low-energy γ -ray (0.1-30 MeV) sky has been relatively unexplored since the decommissioning of the COMPTEL instrument on the Compton Gamma-Ray Observatory (CGRO) satellite in 2000. However, the study of this part of the energy spectrum (the "MeV gap") is crucial for addressing numerous unresolved questions in high-energy and multi-messenger as…
New Yarkovsky drift detections using astrometric observations of NEAs
Lisa, Bedini; Giacomo, Tommei
The Yarkovsky drift represents the semi-major axis variation of a celestial body due to the Yarkovsky effect. This thermodynamic effect acts more significantly on bodies with a diameter between ≈10 m and ≈30 km . Therefore, the orbits of many minor bodies of the solar system are affected: knowing the value of the Yarkovsky drift can be crucial to …
Forward modelling low-spectral-resolution Cassini/CIRS observations of Titan
Nixon, Conor A.; Irwin, Patrick G. J.; Teanby, Nicholas A. +1 more
The Composite InfraRed Spectrometer (CIRS) instrument onboard the Cassini spacecraft performed 8.4 million spectral observations of Titan at resolutions between 0.5-15.5 cm-1. More than 3 million of these were acquired at a low spectral resolution (SR) (13.5-15.5 cm-1), which have excellent spatial and temporal coverage in ad…
