Discovery of a radio jet in the Cloverleaf Quasar at z = 2.56
Lei Zhang, Zhi-Yu Zhang, James. W. Nightingale +10
The fast growth of supermassive black holes and their feedback to the host galaxies play an important role in regulating the evolution of galaxies, especially in the early Universe…
Multiple gas phases in supernova remnant IC 443: mapping shocked H with VLT/KMOS
Yunwei Deng, Zhi-Yu Zhang, Ping Zhou +8
Supernovae and their remnants provide energetic feedback to the ambient interstellar medium (ISM), which is often distributed in multiple gas phases. Among them, warm molecular hyd…
The Volumetric Extended-Schmidt Law: A Unity Slope
Kaiyi Du, Yong Shi, Zhi-Yu Zhang +5
We investigate the extended-Schmidt (ES) law in volume densities ( ) for spatially-resolved regions in spiral,…
Non-detection of Broad Hydrogen Radio Recombination Lines in Circinus Galaxy
Junzhi Wang, Yong Shi, Zhi-Yu Zhang +5
The line widths of broad line regions (BLRs) of AGNs are key parameters for understanding the central super massive black holes (SMBHs). However, due to obscuration from dusty toru…
Unveiling the formation of NGC 2915 with MUSE: A counter-rotating stellar disk embedded in a disordered gaseous environment
Yimeng Tang, Bojun Tao, Hong-Xin Zhang +6
NGC 2915 is a unique nearby galaxy that is classified as an isolated blue compact dwarf based on its optical appearance but has an extremely extended H i gas disk with prominent Sd…
The HI Gas Disk Thickness of the Ultra-diffuse Galaxy AGC 242019
Xin Li, Yong Shi, Zhi-Yu Zhang +5
Ultra-diffuse galaxies (UDGs) are as faint as dwarf galaxies but whose sizes are similar to those of spiral galaxies. A variety of formation mechanisms have been proposed, some of…
