The Effect of Bars on the Ionized ISM: Optical Emission Lines from Milky Way Analogs
Dhanesh Krishnarao, Christy Tremonti, Amelia Fraser-McKelvie +15
Gas interior to the bar of the Milky Way has recently been shown as the closest example of a Low Ionization (Nuclear) Emission Region--LI(N)ER--in the universe. To better understan…
Discovery of High-Velocity H Emission in the Direction of the Fermi Bubble
Dhanesh Krishnarao, Robert A. Benjamin, L. Matthew Haffner
Wisconsin H-Alpha Mapper (WHAM) observations reveal high-velocity and [NII] emission lines in the same direction and velocity as ultraviolet absorption-line features t…
Discovery of a Thirty-Degree Long Ultraviolet Arc in Ursa Major
A. Bracco, R. A. Benjamin, M. I. R. Alves +6
Our view of the interstellar medium of the Milky Way and the universe beyond is affected by the structure of the local environment in the Solar neighborhood. Here, we present the d…
Magnetic Field Morphology in Interstellar Clouds with the Velocity Gradient Technique
Yue Hu, Ka Ho Yuen, Victor Lazarian +6
Magnetic fields, while ubiquitous in many astrophysical environments, are challenging to measure observationally. Based on the properties of anisotropy of eddies in magnetized turb…
