Dr. Federico Fraternale at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, has been awarded a $824,132 NASA heliophysics grant to develop new global models of the heliosphere that incorporate interstellar neutral atoms that can help reveal the properties of space beyond the farthest reaches of the Sun’s influence.
Janice Lee, Chief Scientist at the International Gemini Observatory, leads the JWST Treasury Survey for the PHANGS (Physics at High Angular resolution in Nearby Galaxies) collaboration to study how star formation affects the evolution of galaxies. These observations are providing new insights into how some of the smallest-scale processes in our Universe — the beginnings of star formation — impact the evolution of the largest objects in our cosmos: galaxies.
As part of the JWST Cycle 1 Treasury Program, researchers from UC San Diego have released their findings on polycyclic aromatic hydrocarbons in the interstellar medium of nearby galaxies.
While moving around within the gas in the interstellar medium, cosmic rays kickstart the background protons, which causes a collective plasma wave movement akin to ripples on a lake. The big question is how cosmic rays deposit their momentum into the background plasma. In Physics of Plasmas, plasma astrophysicists review recent developments within the field of studying the streaming instability triggered by cosmic rays, which likely have more impacts on galactic dynamics and the star formation cycle than previously known.
