Far-Infrared and submillimeter properties of SDSS galaxies in the Herschel ATLAS science demonstration phase field
Wu, Hong; Zhu, Yi-Nan; Zhou, Zhi-Min +1 more
Using the Herschel ATLAS science demonstration phase data cross-identified with SDSS DR7 spectra, we select 297 galaxies with F250µm > 5σ. The sample galaxies are classified into five morphological types, and more than 40% of the galaxies are peculiar/compact galaxies. The peculiar galaxies show higher far-infrared/submillimete…
A multi-wavelength study of the gravitational lens COSMOS J095930+023427
Paolillo, Maurizio; Cao, Shuo; Zhu, Zong-Hong +1 more
We present a multi-wavelength study of the gravitational lens COSMOS J095930+023427 (z1 = 0.892), together with the associated galaxy group along the line of sight located at z ~ 0.7, and the lensed background galaxy. The source redshift is currently unknown, but estimated to be at zs ~ 2. This analysis is based on publicly a…
Gravitationally lensed extended sources: the case of QSO RXJ0911
Diep, Pham Ngoc; Nhung, Pham Tuyet; Hoai, Do Thi +6 more
After a brief reminder of the mechanism of gravitational lensing of extended sources, the particular case of the host galaxy of QSO RXJ0911, a high redshift (z ~ 2.8) quadruply imaged quasar, is explored. The non linearity of the problem, together with the proximity of the source to a cusp of the lens inner caustic, has important consequences on t…
Sequential clustering of star formations in IC 1396
Li, Jin-Zeng; Huang, Ya-Fang
We present a comprehensive study of the H II region IC 1396 and its star forming activity, in which multi-wavelength data ranging from the optical to the near- and far-infrared were employed. The surface density distribution of all the 2MASS sources with a certain detection toward IC 1396 indicates the existence of a compact cluster spatially cons…
