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,…
The hidden side of cosmic star formation at z > 3: Bridging optically-dark and Lyman break galaxies with GOODS-ALMA
Mengyuan Xiao, David Elbaz, Carlos Gómez-Guijarro +37
Our current understanding of the cosmic star formation history at z>3 is primarily based on UV-selected galaxies (i.e., LBGs). Recent studies of H-dropouts have revealed that we ma…
The jet formation mechanism of Gamma-ray Narrow-line Seyfert 1 Galaxies
Chen Yongyun, Gu Qiusheng, Fan Junhui +4
Under the coronal magnetic field, we estimate the maximal jet power of the Blandford-\Znajek (BZ) mechanism, Blandford-\Payne (BP) mechanism, and hybrid model. The jet power of the…
Sub-percentage measure of distances to redshift of 0.1 by a new cosmic ruler
Yong Shi, Yanmei Chen, Shude Mao +4
Distance-redshift diagrams probe expansion history of the Universe. We show that the stellar mass-binding energy (massE) relation of galaxies proposed in our previous study offers…
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…
Dense Gas and Star Formation in Nearby Infrared Bright Galaxies: APEX survey of HCN and HCO+ J=2-1
Jing Zhou, Zhi-Yu Zhang, Yu Gao +6
Both Galactic and extragalactic studies on star formation suggest that stars form directly from dense molecular gas. To trace such high volume density gas, HCN and HCO+ J=1-0 have…
