The IBEX-Lo instrument on board the Interstellar Boundary Explorer (IBEX) mission samples interstellar neutral (ISN) helium atoms penetrating heliosphere from very local medium (VLISM). In this study, we analyze ISN observations covering a complete solar cycle, 2009 through 2020 using comprehensive uncertainty analysis including statistical and systematic sources.W e employ Warsaw Test Particle...

The choice of summary statistics is a crucial step in approximate Bayesian computation (ABC). Since statistics are often not sufficient, this choice involves a trade-off between loss of information and reduction of dimensionality. The latter may increase the efficiency of ABC. Here, we propose an approach for choosing summary statistics based on boosting, a technique from the machine-learning l...

[1] The solar wind continuously flows out from the Sun and directly interacts with the surfaces of dust and airless planetary bodies throughout the solar system. A significant fraction of solar wind ions reflect from an object’s surface as energetic neutral atoms (ENAs). ENA emission from the Moon was first observed during commissioning of the Interstellar Boundary Explorer (IBEX) mission on 3 ...

The Alpine ibex is one of the finest examples how human’s attitude towards nature changing by becoming aware biodiversity conservation. On 30th anniversary first reintroduction in Orobie Alps, a three year long Citizen Science Project started June 2017 (‘Stambecco e Lombardia’). Nowadays, complementary tool that can be used data collection citizen science; its use among scientific community inc...

IBEX is a open-source C++ library for constraint processing over real numbers. It provides reliable algorithms for handling non-linear constraints. In particular, roundoff errors are also taken into account. It is based on interval arithmetic and affine arithmetic. The main feature of IBEX is its ability to build strategies declaratively through the contractor programming paradigm. It can also ...

The direct measurement of the energetic neutral atoms originating from the heliospheric termination shock and beyond as well as neutral interstellar gas penetrating into the heliosphere requires a very sensitive neutral particle imaging instrument in the energy range of 10-1000 eV. We present the development of the prototype of the low energy sensor for the Interstellar Boundary Explorer (IBEX)...
