We investigate phenomena such as turbulence, the generation of magnetic fields from the dynamo effect, the acceleration of charged particles due to magnetic recconnection, and plasma waves. We focus our research on astrophysical systems such as the solar upper atmosphere and corona, the solar wind, planetary magnetospheres and accretion disks.<\/p><p>Numerical modeling is made through simulation of the magnetohydrodynamic equations using codes developed at IAFE and run in the Institute&#8217;s CAPS (Cluster for Astrophysical Plasma Simulations) and HOPE clusters. This work is complemented with other areas of research that use other tools to study the Sun, planets and the interplanetary medium.<\/p><p><img decoding=\"async\" class=\"size-full wp-image-1991 aligncenter\" src=\"http:\/\/www.iafe.uba.ar\/nuevaweb\/wp-content\/uploads\/2023\/08\/plasma-turbulento.png\" alt=\"\" width=\"256\" height=\"128\" \/><\/p><p>Figure: Heat map of vorticity in a turbulent plasma (Gomez et al., 2014)<\/p><p>In addition, measurements provided by spaccraft such as Mars Global Surveyor, Cassini, MAVEN, MMS, and STEREO are analyzed and interpreted in order to understand the physics of the heliosphere.<\/p><p><img decoding=\"async\" class=\"size-medium wp-image-1992 aligncenter\" src=\"http:\/\/www.iafe.uba.ar\/nuevaweb\/wp-content\/uploads\/2023\/08\/cassini-300x212.png\" alt=\"\" width=\"300\" height=\"212\" srcset=\"https:\/\/www.iafe.uba.ar\/en\/wp-content\/uploads\/2023\/08\/cassini-300x212.png 300w, https:\/\/www.iafe.uba.ar\/en\/wp-content\/uploads\/2023\/08\/cassini-768x543.png 768w, https:\/\/www.iafe.uba.ar\/en\/wp-content\/uploads\/2023\/08\/cassini.png 842w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p><p>Figure: Titan&#8217;s magnetosphere according to the observations of the Cassini spacecraft (Bertucci, 2021)<\/p><p>On the other hand, the LAMP group (<a href=\"https:\/\/www.iafe.uba.ar\/u\/lamp\/\">https:\/\/www.iafe.uba.ar\/u\/lamp\/<\/a>) also makes contributions to the study of dynamic processes in astrophysical plasmas, through in-situ measurements of plasma conditions and magnetic forces of the interplanetary medium.
