CHANG-ES XXXV: Cosmic Ray Transport and Magnetic Field Structure of NGC 3556 at 3 GHz
Jianghui Xu, Yang Yang, Jiang-Tao Li +7
Radio halos of edge-on galaxies are crucial for investigating cosmic ray propagation and magnetic field structures in galactic environments. We present VLA C-configuration S-band (…
Probing the He II re-Ionization ERa via Absorbing C IV Historical Yield (HIERACHY) II: Project Design, Current Status, and Examples of Initial Data Products
Jiang-Tao Li, Xiaodi Yu, Huiyang Mao +22
The He II reionization epoch is expected to take place at . In this stage, the helium and metals in the inter-galactic medium (IGM) are further ionized with additional co…
eDIG-CHANGES III: the lagging eDIG revealed by multi-slit spectroscopy of NGC 891
Li-Yuan Lu, Jiang-Tao Li, Carlos J. Vargas +9
The kinematic information of the extraplanar diffuse ionized gas (eDIG) around galaxies provides clues to the origin of the gas. The eDIG-CHANGES project studies the physical and k…
eDIG-CHANGES II: Project Design and Initial Results on NGC 3556
Jiang-Tao Li, Li-Yuan Lu, Zhijie Qu +19
The extraplanar diffuse ionized gas (eDIG) represents ionized gases traced by optical/UV lines beyond the stellar extent of galaxies. We herein introduce a novel multi-slit narrow-…
Pressure Balance and Energy Budget of the Nuclear Superbubble of NGC 3079
Jiang-Tao Li, Wei Sun, Li Ji +1
Superbubbles in the nuclear region of galaxies could be produced by the AGN or nuclear starburst via different driving forces. We report analysis of the multi-wavelength data of th…
CHANG-ES. XXX. 10 kpc Radio Lobes in The Sombrero Galaxy
Yang Yang, Jiang-Tao Li, Theresa Wiegert +8
We report the discovery of the 10 kilo-parsec (kpc) scale radio lobes in the Sombrero galaxy (NGC 4594), using data from the Continuum Halos in Nearby Galaxies - an Expanded Very L…
