An Apparent Redshift Dependence of Quasar Continuum: Implication for Cosmic Dust Extinction?
Xiaoyi Xie, Shiyin Shen, Zhengyi Shao +1
We investigate the luminosity and redshift dependence of the quasar continuum by means of composite spectrum using a large non-BAL radio-quiet quasar sample drawn from the Sloan Di…
The Evolution and Star Formation History of M33
Xiaoyu Kang, Ruixiang Chang, Jun Yin +4
We construct a parameterized model to explore the main properties of the star formation history of M33. We assume that the disk originates and grows by the primordial gas infall an…
Chemical Evolution of Dwarf Irregular and Blue Compact Galaxies
Jun Yin, Francesca Matteucci, Giovanni Vladilo
Dwarf irregular and blue compact galaxies are very interesting objects since they are relatively simple and unevolved. We present new models for the chemical evolution of these gal…
