The Kinematic Structure of Magnetically Aligned HI Filaments
Doyeon Avery Kim, Susan E Clark, Mary E Putman +1
We characterize the kinematic and magnetic properties of HI filaments located in a high Galactic latitude region ( and ). We extra…
Census of Gaseous Satellites around Local Spiral Galaxies
Jingyao Zhu, Mary E Putman
We present a search for gas-containing dwarf galaxies as satellite systems around nearby spiral galaxies using 21 cm neutral hydrogen (HI) data from the Arecibo Legacy Fast ALFA (A…
HI filaments as potential compass needles? Comparing the magnetic field structure of the Small Magellanic Cloud to the orientation of GASKAP-HI filaments
Y. K. Ma, N. M. McClure-Griffiths, S. E. Clark +12
High-spatial-resolution HI observations have led to the realisation that the nearby (within few hundreds of parsecs) Galactic atomic filamentary structures are aligned with the amb…
A Comprehensive Investigation of Metals in the Circumgalactic Medium of Nearby Dwarf Galaxies
Yong Zheng, Yakov Faerman, Benjamin D. Oppenheimer +7
Dwarf galaxies are found to have lost most of their metals via feedback processes; however, there still lacks consistent assessment on the retention rate of metals in their circumg…
