Absorption features in the quasar HS 1603+3820 II. Distance to the absorber from photoionisation modelling
A. Rozanska, M. Nikolajuk, B. Czerny +4
We present photoionisation modelling of the intrinsic absorber in the bright quasar HS 1603+3820. We construct spectral energy distribution using optical/UV/X-ray observations as a…
Strongly Variable z=1.48 FeII and MgII Absorption in the Spectra of z=4.05 GRB 060206
H. Hao, K. Z. Stanek, A. Dobrzycki +9
We report on the discovery of strongly variable FeII and MgII absorption lines seen at z=1.48 in the spectra of the z=4.05 GRB 060206 obtained between 4.13 to 7.63 hours (observer…
"Anomalous" Optical GRB Afterglows are Common: Two z~4 Bursts, GRB 060206 and 060210
K. Z. Stanek, X. Dai, J. L. Prieto +9
We report on two recent z~4 gamma-ray bursts (GRBs), GRB 060206 and GRB 060210, for which we have obtained well-sampled optical light curves. Our data, combined with early optical…
Discovery of nine quasars behind the Large Magellanic Cloud
A. Dobrzycki, L. Eyer, K. Z. Stanek +1
We present the discovery of nine quasars behind the Large Magellanic Cloud, with emission redshifts ranging from 0.07 to 2.0. Six of them were identified as part of the systematic…
Variability-selected QSO candidates in OGLE-II Galactic Bulge fields
T. Sumi, P. R. Wozniak, L. Eyer +9
We present 97 QSO candidates in 48 Galactic Bulge fields of the Optical Gravitational Lensing Experiment II (OGLE-II) covering about 11 square degrees, which are selected via their…
New X-ray quasars behind the Small Magellanic Cloud
A. Dobrzycki, K. Z. Stanek, L. M. Macri +1
We present five X-ray quasars behind the Small Magellanic Cloud, increasing the number of known quasars behind the SMC by ca. 40%. They were identified via follow-up spectroscopy o…
