The local and global properties of different types of supernova host galaxies
Li Zhou, Yan-Chun Liang, Jun-Qiang Ge +5
By using Data Analysis Pipeline (DAP) products of Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), which are publicly available from the SDSS Data Release 15, we analyz…
The local properties of supernova explosions and their host galaxies
Li Zhou, Yan-Chun Liang, Jun-Qiang Ge +3
We aim to understand the properties at the locations of supernova (SN) explosion in their host galaxies and compare with the global properties of the host galaxies. We use the inte…
Formation of the Abundance Boundaries of the Heavier Neutron-capture Elements in Metal-poor Stars
Guochao Yang, Hongjie Li, Nian Liu +5
The abundance scatter of heavier r-process elements (Z > 56) relative to Fe ([r/Fe]) in metal-poor stars preserves excellent information of the star formation history and provides…
Footprints of the weak s-process in the carbon-enhanced metal-poor star ET0097
Guochao Yang, Hongjie Li, Nian Liu +3
Historically, the weak s-process contribution to metal-poor stars is thought to be extremely small, due to the effect of the secondary-like nature of the neutron source 22Ne(a;n)25…
Relations of stellar mass between electron temperature-based metallicity of star-forming galaxies in a wide mass range
WeiBin Shi, YanChun Liang, Xu Shao +7
We select 947 star-forming galaxies from SDSS-DR7 with [O~{\sc iii}]4363 emission lines detected at a signal-to-noise {ratio }larger than 5. Their electron temperatures and d…
Modelling narrow-line regions of active galaxies in the Sloan Digital Sky Survey - I.Sample selection and physical conditions
Zhitai Zhang, Yanchun Liang, François Hammer
We systematically determine the electron density and electron temperature of active galaxies and star-forming galaxies using spectroscopy from the SDSS DR7, while mainly focusing o…
