Large-Field Multicolor Study of Abell 168 : Subclusters, Dynamics and Luminosity Functions
Yanbin Yang, Xu Zhou, Qirong Yuan +4
This paper presents a multicolor study of the nearby cluster of galaxies Abell 168 (z=0.045) with 13 intermediate-band filters in the Beijing-Arizona-Taiwan-Connecticut (BATC) filt…
Multicolor Photometry of the Galaxies in Abell 2255 by the BATC and SDSS Surveys
Qirong Yuan, Xu Zhou, Zhaoji Jiang
We present our optical multicolor photometry for the nearby cluster of galaxies Abell 2255 with 13 intermediate filters in the BATC system. The spectral energy distributions (SEDs)…
H-alpha +[NII] Observations of the HII Regions in M81
W. P. Lin, X. Zhou, D. Burstein +2
In a first of a series of studies of the H-alpha + [NII] emission from nearby spiral galaxies, we present measurements of H-alpha + [NII] emission from HII regions in M81. Our meth…
Galactic structure studies with BATC star counts
Cuihua Du, Xu Zhou, Jun Ma +6
We report the first results of star counts carried out with the National Astronomical Observatories (NAOC) 60/90 cm Schmidt Telescope in 15 intermediate-band filters from 3000 to 1…
