Extending the Eigenvector 1 Space to the Optical Variability of Quasars
Yufeng Mao, Jing Wang, Jianyan Wei
We introduce a new physical parameter, the optical variability amplitude, to the well-established Eigenvector 1 space of quasars and test a sample of long-term B-band light curves…
The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125
Adria C. Updike, Joshua B. Haislip, Melissa C. Nysewander +52
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the prese…
Testing the External Shock Model of Gamma-Ray Bursts using the Late-Time Simultaneous Optical and X-ray Afterglows
Yuji Urata, Ryo Yamazaki, Takanori Sakamoto +21
We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-ban…
Photometric monitoring of the ROSAT selected weak-line T Tauri stars in the Taurus-Auriga field
Li-Feng Xing, Xiao-Bin Zhang, Jian-Yan Wei
We monitored the light variations of 22 weak-line T Tauri stars (WTTS) discovered among the X-ray sources in the field of the Taurus-Auriga cloud. The photometric variability of 12…
