Credit: aside from the tagged logo of the associated scientific collaborations in the videos above, information on the names of the lead scientists and the creators of the visuals is either in the rolling credits at the beginning or the end of the videos. Although may be trivial, it is important to mention that I did not make these videos myself. First of the three videos above is from the BOSS and eBOSS surveys as part of the Sloan Digital Sky Survey collaboration projetcs. The second video belongs to Dark Energy Survey Instrument collaboration.
Galactic magnetism and its effect on galaxy formation and AGN feedback
The presence of magnetic fields in galaxies at all spatial scales has been known for more than two decades yet the magnetic field structure in the vicinity of the galaxy's inner-bar and active galactic nucleus (AGN) and despite plausible theories, our understanding of the formation of spiral arms and their role in galaxy evolution is largely unknown. The search for proxies to inner dynamics of galactic structure has been a far reaching goal before high fidelity IR dust polarization detection was debuted by SOFIA's HAWC+. SOFIA'e legacy program, SALSA (PI: E. Lopez-Rodriguez) constructed a FIR polarimetric survey of nearby galaxies. By combining FIR dust polarization maps with radio polarimetric and optical spectroscopic observations, SALSA team obtained the magnetic field strength/structure and gas dynamics as a function of host galaxy properties and kpc-scale galactic environment. |
