Testing the axion-conversion hypothesis of 3.5 keV emission with polarization
Yan Gong, Xuelei Chen, Hua Feng
The recently measured 3.5 keV line in a number of galaxy clusters, the Andromeda galaxy (M31) and the Milky Way (MW) center can be well accounted for by a scenario in which dark ma…
Revisiting the structure and spectrum of the magnetic-reconnection-heated corona in luminous AGNs
J. Y. Liu, ErLin Qiao, B. F. Liu
It is believed that the hard X-ray emission in the luminous active galactic nuclei (AGNs) is from the hot corona above the cool accretion disk. However, the formation of the corona…
Gamma-ray burst progenitors
Andrew Levan, Paul Crowther, Richard de Grijs +3
We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use thre…
Ultraluminous X-ray bursts in two ultracompact companions to nearby elliptical galaxies
Jimmy A. Irwin, W. Peter Maksym, Gregory R. Sivakoff +8
An X-ray flaring source was found near the galaxy NGC 4697. Two flares were seen, separated by four years. The flux increased by a factor of 90 on a timescale of about one minute.…
Evidence for magnetar formation in broad-lined type Ic supernovae 1998bw and 2002ap
L. J. Wang, H. Yu, L. D. Liu +6
Broad-lined type Ic supernovae (SNe Ic-BL) are peculiar stellar explosions that distinguish themselves from ordinary SNe. Some SNe Ic-BL are associated with long-duration (\gtrsim…
A New Measurement of the Spectral Lag of Gamma-Ray Bursts and its Implications for Spectral Evolution Behaviors
Lang Shao, Bin-Bin Zhang, Fu-Ri Wang +9
We carry out a systematical study of the spectral lag properties of 50 single-pulsed Gamma-Ray Bursts (GRBs) detected by Fermi/GBM. By dividing the light curves into multiple conse…
The second closest gamma-ray burst: sub-luminous GRB 111005A with no supernova in a super-solar metallicity environment
Michał J. Michałowski, Dong Xu, Jamie Stevens +17
We report the detection of the radio afterglow of a long gamma-ray burst (GRB) 111005A at 5-345 GHz, including the very long baseline interferometry observations with the positiona…
Curvature of the spectral energy distribution, the dominant process for inverse Compton component and other jet properties in Fermi 2LAC blazars
R. Xue, D. Luo, L. M. Du +7
We fit the spectral energy distributions (SEDs) of members of a large sample of Fermi 2LAC blazars to synchrotron and inverse Compton (IC) models. Our main results are as follows.…
NuSTAR observations of WISE J1036+0449, a Galaxy at z obscured by hot dust
C. Ricci, R. J. Assef, D. Stern +34
Hot, Dust-Obscured Galaxies (Hot DOGs), selected from the WISE all sky infrared survey, host some of the most powerful Active Galactic Nuclei (AGN) known, and might represent an im…
Very Bright Prompt and Reverse Shock Emission of GRB 140512A
Xiao-Li Huang, Li-Ping Xin, Shuang-Xi Yi +5
We report our observations of very bright prompt optical and reverse shock (RS) optical emission of GRB 140512A and analyze its multi-wavelength data observed with the {\em Swift}…
Highly polarized components of integrated pulse profiles
P. F. Wang, J. L. Han
Highly polarized components of pulse profiles are investigated by analyzing observational data and simulating the emission processes. The highly polarized components appear at the…
The intrinsic line width of the Fe Ka line of AGN
Jiren Liu
X-ray fluorescent lines are unique features of the reflection spectrum of the cold torus when irradiated by the central AGN. Their intrinsic line widths can be used to probe the li…
Time-Variable Aluminum Absorption in the Polar AR Ursae Majoris, and an Updated Estimate for the Mass of the White Dwarf
Yu Bai, Stephen Justham, JiFeng Liu +3
We present spectra of the extreme polar AR Ursae Majoris (AR UMa) which display a clear Al I absorption doublet, alongside spectra taken less than a year earlier in which that feat…
The Spectral Energy Distributions of Fermi Blazars
J. H. Fan, J. H. Yang, Y. Liu +7
(Abridged) In this paper, multi-wavelength data are compiled for a sample of 1425 Fermi blazars to calculate their spectral energy distributions (SEDs). A parabolic function, $\log…
Sharp Chandra View of ROSAT All-Sky Survey Bright Sources: I. Improvement of Positional Accuracy
Shuang Gao, Song Wang, Jifeng Liu
The ROSAT All-Sky Survey (RASS) represents one of the most complete and sensitive soft X-ray all-sky surveys to date. However, the deficient positional accuracy of the RASS Bright…
Solving the 56Ni puzzle of magnetar-powered broad-lined type Ic supernovae
Ling-Jun Wang, Yan-Hui Han, Dong Xu +4
Broad-lined type Ic supernovae (SNe Ic-BL) are of great importance because their association with long-duration gamma-ray bursts (LGRBs) holds the key to deciphering the central en…
The History of GRB Outflows: Ejection Lorentz Factor and Radiation Location of X-Ray Flares
Hui-Jun Mu, Da-Bin Lin, Shao-Qiang Xi +6
We present time-resolved spectral analysis of the steep decay segments of 29 bright X-ray flares of gamma-ray bursts (GRBs) observed with the Swift/X-ray telescope, and model their…
Rotational evolution of magnetars in the presence of a fallback disk
H. Tong, W. Wang, X. W. Liu +1
Magnetars may have strong surface dipole field. Observationally, two magnetars may have passive fallback disks. In the presence of a fallback disk, the rotational evolution of magn…
