Biases in galaxy spectral analysis from strong lensing differential magnification effect and correction methods
Wenshuo Xu, Dandan Xu, Xinzhong Er +1
Strong gravitational lensing has significantly advanced the study of high-redshift galaxies, but the differential magnification effect inevitably introduces biases in the spectral…
Photometric properties of classical bulge and pseudo-bulge galaxies at
Jia Hu, Qifan Cui, Lan Wang +2
We compare the photometric properties and specific star formation rate (sSFR) of classical and pseudo-bulge galaxies with at , select…
Resolved properties of classical bulge and pseudo-bulge galaxies
Jia Hu, Lan Wang, Junqiang Ge +2
We compare properties of classical and pseudo-bulges and properties of their hosting galaxies selected from the MaNGA survey. Bulge types are identified based on the S$\mathrm{\acu…
A strong He II 1640 emitter with extremely blue UV spectral slope at : presence of Pop III stars?
Xin Wang, Cheng Cheng, Junqiang Ge +12
Cosmic hydrogen reionization and cosmic production of first metals are major phase transitions of the universe occurring during the first billion years after the Big Bang, however…
Are High Massive Blue Spiral Galaxies Rejuvenated Systems?
Cai-Na Hao, Xiaoyang Xia, Yong Shi +5
Quiescent galaxies generally possess denser cores than star-forming galaxies with similar mass. As a measurement of the core density, the central stellar mass surface density withi…
