We report the observation of new properties of primary cosmic rays, neon (Ne), magnesium (Mg), and silicon (Si), measured in the rigidity range 2.15 GV to 3.0 TV with 1.8 ×10 6 Ne , 2.2 ×10 6 Mg , and 1.6 ×10 6 Si nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The Ne and Mg spectra have identical

Solar jets observed at the limb are important to determine the location of reconnection sites in the corona. In this study, we investigate six recurrent hot and cool jets occurring in the active region NOAA 12644 as it is crossing the west limb on April 04, 2017. These jets are observed in all the UV/EUV filters of SDO/AIA and in cooler temperature

We present a point-source detection algorithm that employs the second-order Spherical Mexican Hat wavelet filter (SMHW2), and use it on C-Band All-Sky Survey (C-BASS) northern intensity data to produce a catalogue of point sources. This catalogue allows us to cross-check the C-BASS flux-density scale against existing source surveys, and provides

The development of space instrumentation under the CubeSat standard has launched a "New Space" era in which missions develop much faster and at considerably lower cost than traditional space exploration. Vastly used for communications and EO science, CubeSats also have incoming possibilities for Astrophysics research, with the potential to be a

In the absence of an initial seed, the Biermann battery term of a non-ideal induction equation acts a source that generates weak magnetic fields. Here, we study this mechanism in the context of partially ionized plasmas, using a model in which the charged and neutral components of the plasma are treated as two different fluids that interact by

We present results from deep MUSE data in extended mode obtained for three planetary nebulae (PNe) with previously reported high abundance discrepancy factors (ADF). The spatially resolved emission maps of recombination lines (ORLs) and collisionally excited lines (CELs) of oxygen ions point to two different plasma components: one hot component
