Seven broad absorption line quasars with excess broad band absorption near 2250 Å

Shaohua Zhang, Jian Ge, Peng Jiang +6

We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results fr…

Photometric Redshifts in the Hawaii-Hubble Deep Field-North (H-HDF-N)

G. Yang, Y. Q. Xue, B. Luo +11

We derive photometric redshifts (\zp) for sources in the entire ( deg) Hawaii-Hubble Deep Field-North (\hdfn) field with the EAzY code, based on point spread function-…

Chandra and MMT observations of low-mass black hole active galactic nuclei accreting at low rates in dwarf galaxies

W. Yuan, H. Zhou, L. Dou +3

We report on Chandra X-ray observations of four candidate low-mass black hole (<10^6Msun) active galactic nuclei (AGNs) that have the estimated Eddington ratios among the lowest (~…
