The connection between radio and γ-ray emission in Fermi/LAT blazars

引用

Research in Astronomy and Astrophysics 2012年第11期12卷 1475-1485页

作者： Xu-Liang Fan Jin-Ming Bai Hong-Tao Liu Liang Chen neng-Hui liao National Astronomical Observatories / Yunnan Observatory Chinese Academy of SciencesKunming 650011 China Key Laboratory for the Structure and Evolution of Celestial Objects Chinese Academy ofSciences Kunming 650011 China Key Laboratory for Research in Galaxies and Cosmology Shanghai Astronomical ObservatoriesChinese Academy of Sciences Shanghai 200030 China Graduate University of Chinese Acaciemy of Sciences Beijing 100049 China

We collect the second Large Area Telescope AGN catalog （2LAC） and Monitor of Jets in AGN with VLBA Equipment （MOJAVE） quasi-simultaneous data to investigate the radio-γ connection of blazars. The cross sample contains 166 sources. The statistical analysis based on this sample confirms positive correlations between these two bands, but the correlations become weaker as the γ-ray energy increases. The statistical results between various parameters show negative correla- tions of γ-ray photon spectral index with γ-ray loudness for both Flat Spectrum Radio Quasars （FSRQs） and BL Lacertae objects, positive correlations of γ-ray variability index with the γ-ray loudness for FSRQs, a negative correlation of the γ-ray variabil- ity index with the γ-ray photon spectral index for FSRQs, and negative correlations of γ-ray photon spectral index with γ-ray luminosity for FSRQs. These results suggest that the γ-ray variability may be due to changes inside the γ-ray emission region like the injected power, rather than changes in the photon density of the external radiation fields, and the variability amplitude tends to be larger as the γ-rays are closer to the high energy peak of the spectral energy distribution （SED）. No correlation of variabil- ity index found for BL Lacertae objects implies that variability behavior may differ below and above the peak energy.

Mass transport phenomena in copper nanowires at high current density

引用

Nano Research 2016年第4期9卷 1071-1078页

作者： Yu-Ting Huang Chun-Wei Huang Jui-Yuan Chen Yi-Hsin Ting Shao-Liang Cheng Chien-neng liao Wen-Wei Wu Department of Materials Science and Engineering Chiao Tung University I001 University Road Hsinchu 30010 Department of Chemical and Materials Engineering Central University Zhongda Road Taoyuan 32001 Department of Materials Science and Engineering Tsing Hua University 101 Section 2 Kuang-Fu Road Hsinchu 30013

Electromigration in Cu has been extensively investigated as the root cause of typical breakdown failure in Cu interconnects. In this study Cu nanowires connected to Au electrodes are fabricated and observed using in situ transmission electron microscopy to investigate the electro- and thermo-migration processes that are induced by direct current sweeps. We observe the dynamic evolution of different mass transport mechanisms. A current density on the order of 106 A/cm^2 and a temperature of approximately 400 ℃ are sufficient to induce electro- and thermo-migration, respectively. Observations of the migration processes activated by increasing temperatures indicate that the migration direction of Cu atoms is dependent on the net force from the electric field and electron wind. This work is expected to support future design efforts to improve the robustness of Cu interconnects.

Is BZB J1450+5201 the most distant gamma-ray BL Lacertae object?

引用

Research in Astronomy and Astrophysics 2015年第3期15卷 313-326页

BL Lacertae （BL Lac） objects at high redshifts （z ≥ 2） are rarely detected. Through careful analysis of its Sloan Digital Sky Survey spectrum, BZB J1450＋5201 is confirmed to be a high-z BL Lac object with z ≥ 2.471 by identifying the Lyα 1216 and CIV 1548/1550 absorption lines. This indicates that BZB J1450＋5201 is the most distant BL Lac object discovered to date. Careful analysis of the five-year Fermi-LAT data of 2FGL J1451.0＋5159 shows that its γ-ray emission is robust with a confidence level of 6.2σ at 1-3 GeV and 6.7σ at 3-10 GeV. This analysis with the five-year data overcomes confusion with its bright neighbor, which is a problem when analyzing the two-year data. In addition, 2FGL J 1451.0＋5159 is confirmed to be associated with BZB J1450＋5201 using the five-year data. The analysis of multiwavelength data, from radio to γ-ray energies, indicates that BZB J1450＋5201 is an intermediate synchrotron peaked （ISP） source. Its multiwavelength properties are consistent with distributions of other ISP sources at lower redshifts in the second Fermi-LAT AGN catalog. The pure synchrotron self-Compton （SSC） model seems to be disfavored, but the scattering of weak external emission plus the SSC process can provide a satisfactory description of the broadband emission.

碎片盘通常被描述为贫气盘,其气尘比显著低于原行星盘,因此很少在碎片盘中探测到气体.得益于各种灵敏的望远镜,探测到气体的碎片盘的数量正在不断增加,寻找更多的含有气体的碎片盘成为碎片盘研究的重点课题.然而大范围的搜寻非常耗时且低效,因而为了更快更好地遴选探测的目标,需要根据这类源的特性择选更小范围样本.通过统计探测到气体的碎片盘及其宿主恒星的参数总结出这些源的总体特性.为此搜集了已经发表的探测到气体的碎片盘的文献,总计找到37个源,包括探测到CO等冷气体的12个源、CaⅡ等热气体的14个源以及冷热气体共存的11个源.通过统计其宿主恒星的光谱类型、年龄、离地球距离和碎片盘的相对光度、气体质量、尘埃质量等信息,得出了主要结论:宿主恒星多为B型和A型恒星,年龄大部分都小于50 Myr,相对光度分布相比于已知碎片盘更为集中,在10^(-5)-10^(-2)区间范围.
