A Solar System formation analogue in the Ophiuchus star-forming complex
Alves, João; Lin, Douglas N. C.; Forbes, John C.
Anomalies among the daughter nuclei of the extinct short-lived radionuclides in calcium-aluminium-rich inclusions indicate that the Solar System must have been born near a source of the short-lived radionuclides so that they could be incorporated before they decayed away1. γ-rays from one such living short-lived radionuclide, 26
The magnetic field across the molecular warped disk of Centaurus A
Lopez-Rodriguez, Enrique
Magnetic fields are amplified as a consequence of galaxy formation and turbulence-driven dynamos. Galaxy mergers can potentially amplify the magnetic fields from their progenitors, making the magnetic fields dynamically important. However, the effect of mergers on magnetic fields is still poorly understood. We use thermal polarized emission observ…
Optical reconstruction of dust in the region of supernova remnant RX J1713.7−3946 from astrometric data
Krone-Martins, A.; Rowell, G.; Fukui, Y. +5 more
The origin of the radiation observed in the region of the supernova remnant RX J1713.7−3946, one of the brightest TeV emitters, has been debated since its discovery. The existence of atomic and molecular clouds in this object supports the idea that part of the GeV gamma-ray emission in this region originates from proton-proton collisions. However,…
