OQ~208: A New Fe~II Changing-look Active Galactic Nucleus and Implications for the Nature of the Changing-look Phenomenon
J. Wang, W. K. Zheng, D. W. Xu +5
In addition to the traditional hydrogen Balmer emission lines, here we extend the optical changing-look (CL) phenomenon occurring in some active galactic nuclei (AGNs) to the optic…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
Are "Changing-Look'' Active Galactic Nuclei Special in the Coevolution of Supermassive Black Holes and their Hosts? I
J. Wang, W. K. Zheng, T. G. Brink +5
The nature of the so-called ``changing-look'' (CL) active galactic nucleus (AGN), which is characterized by spectral-type transitions within ~yr, remains an open question.…
A fast radio burst source at a complex magnetised site in a barred galaxy
H. Xu, J. R. Niu, P. Chen +71
Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio bursts. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but…
B3\,0749+460A: A New "Changing-Look" Active Galactic Nucleus Associated with X-ray Spectral Slope Variations
J. Wang, W. K. Zheng, D. W. Xu +5
Here we report an identification of B3\,0749+460A as a new double-peaked local "changing-look" active galactic nucleus (CL-AGN) in terms of our multi-epoch spectroscopic analysis.…
A Monte Carlo approach to magnetar-powered transients: II. Broad-lined type Ic supernovae not associated with GRBs
Ling-Jun Wang, Zach Cano, Shan-Qin Wang +11
Broad-lined type Ic supernovae (SNe Ic-BL) are a subclass of rare core collapse SNe whose energy source is debated in the literature. Recently a series of investigations on SNe Ic-…
Space Telescope and Optical Reverberation Mapping Project. IV. Anomalous behavior of the broad ultraviolet emission lines in NGC 5548
M. R. Goad, K. T. Korista, G. De Rosa +99
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert~1 galaxy NGC 5548 performed from 2014 February to July, the…
Space Telescope and Optical Reverberation Mapping Project. III. Optical Continuum Emission and Broad-Band Time Delays in NGC 5548
M. M. Fausnaugh, K. D. Denney, A. J. Barth +94
We present ground-based optical photometric monitoring data for NGC 5548, part of an extended multi-wavelength reverberation mapping campaign. The light curves have nearly daily ca…
The Optical Luminosity Function of Gamma-ray Bursts deduced from ROTSE-III Observations
X. H. Cui, X. F. Wu, J. J. Wei +16
We present the optical luminosity function (LF) of gamma-ray bursts (GRBs) estimated from a uniform sample of 58 GRBs from observations with the Robotic Optical Transient Search Ex…
The shallow-decay phase in both optical and x-ray afterglows of Swift GRB 090529A: Energy injection into a wind-type medium?
L. P. Xin, A. Pozanenko, D. A. Kann +22
The energy injection model is usually proposed to interpret the shallow-decay phase in Swift GRB X-ray afterglows. However, very few GRBs have simultaneous signatures of energy inj…
