Assessment of sky brightness in central Portugal: the Dark Sky destination "Aldeias do Xisto" case study
Domingos Barbosa, Dalmiro Maia, Bruno Morgado +5
A combination of remote sensing techniques, open space data and field testing was developed to derive astronomical and meteorological parameters and assess Dark Sky brightness of t…
A Cloud-native Agile approach to cyber platform prototyping and integration for astronomy: the ENGAGE SKA case
Domingos Barbosa, Diogo Regateiro, João Paulo Barraca +13
The Square Kilometre Array (SKA) Observatory is gearing up the formal construction of its two radio interferometers in Australia and South Africa after the end of design and pre-co…
PASO -- Astronomy and Space Situational Awareness in a Dark Sky Destination
Domingos Barbosa, Bruno Coelho, Miguel Bergano +17
The Pampilhosa da Serra Space Observatory (PASO) is located in the center of the continental Portuguese territory, in the heart of a certified Dark Sky destination by the Starlight…
Theory of Functional Connections and Nelder-Mead optimization methods applied in satellite characterization
Allan Kardec de Almeida Junior, Safwan Aljbaae, Timothée Vaillant +10
The growing population of man-made objects with the build up of mega-constellations not only increases the potential danger to all space vehicles and in-space infrastructures (incl…
Reversible time-step adaptation for the integration of few-body systems
Tjarda C. N. Boekholt, Timothee Vaillant, Alexandre C. M. Correia
The time step criterion plays a crucial role in direct N-body codes. If not chosen carefully, it will cause a secular drift in the energy error. Shared, adaptive time step criteria…
Dedicated symplectic integrators for rotation motions
J. Laskar, T. Vaillant
We propose to use the properties of the Lie algebra of the angular momentum to build symplectic integrators dedicated to the Hamiltonian of the free rigid body. By introducing a de…
