CHANG-ES XLII: Cosmic-Ray Electron Transport and the Spatially Resolved Radio-SFR Relation in Edge-on Galaxies
Jianghui Xu, Volker Heesen, Jiang-Tao Li +6
Radio continuum emission traces star formation in galaxies, but cosmic-ray electron (CRE) propagation between the disk and halo complicates this connection. We present a wide-band,…
Energy Partition in AGN-driven Bubbles of NGC 4438: From Nuclear Bubbles to a Galaxy-scale Outflow
Luan Luan, Jiang-Tao Li, Jianghui Xu +4
Jets launched by accreting supermassive black holes represent a major mode of active galactic nucleus (AGN) feedback. However, how their energy is divided among bulk kinetic motion…
CHANG-ES. XXXVIII. A Thin Radio Halo Shaped by Slow Cosmic-Ray Transport in the Quiescent Galaxy NGC 4565
Jianghui Xu, Jiang-Tao Li, Guilin Liu +11
We present the VLA C-array S-band (2--4 GHz) radio continuum observations of the nearby edge-on spiral galaxy NGC 4565, a target from the Continuum Halos in Nearby Galaxies - an EV…
CO in MASsive Spirals (CO-MASS): an IRAM 30m CO emission line survey of the CGM-MASS sample
Yu Huang, Jiangtao Li, Yan Jiang +4
There exist extremely massive spiral galaxies in isolated environments, with stellar masses several times that of the Milky Way, yet their star formation rates (SFRs) are comparabl…
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…
