Broadband Spectral Properties of MAXI J1348-630 using AstroSat Observations

We present broadband X-ray spectral analysis of the black hole X-ray binary MAXI J1348-630,performed using five AstroSat observations.The source was in the soft spectral state for the first three observations and in the hard state for the last two.The three soft state spectra were modeled using a relativistic thin accretion disk with reflection features and thermal Comptonization.Joint fitting of the soft state spectra constrained the spin parameter of the black hole a_(*)>0.97 and the disk inclination angle i=32.9_(-0.6)^(+4.1)degrees.The bright and faint hard states had bolometric flux a factor of~6 and~10 less than that of the soft state respectively.Their spectra were fitted using the same model except that the inner disk radius was not assumed to be at the last stable orbit.However,the estimated values do not indicate large truncation radii and the inferred accretion rate in the disk was an order of magnitude lower than that of the soft state.Along with earlier reported temporal analysis,AstroS at data provide a comprehensive picture of the evolution of the source.

最高量子相关谱技术在同核偶合常数测定中的应用(英文)

偶合常数是一个重要的ＮＭＲ 参数，其数值与分子中化学键的二面角有关，可以为分子结构研究提供很重要的信息．多维ＮＭＲ谱由于具有较大的化学位移分辨率，因此常常被用来测定同核或异核自旋－ 自旋偶合常数．本文介绍了利用最高量子相关技术（ＭＡＸＹ） 测定同核偶合常数的方法．ＭＡＸＹ 是最近发展的一种多维ＮＭＲ 谱编辑技术，可以使不同官能团（ＣＨ，ＣＨ２ ，ＣＨ３） 的相关峰分布于不同的图谱区域，因此比常规的二维谱具有更高的化学位移分辨率．而且被分离开来的ＮＭＲ 相关峰呈吸收性线型，能清楚地展示各自的偶合分裂特征，可以直接用于测定偶合常数．

WNK1激酶对Maxi K通道的调节作用

目的:研究WNK1激酶对Maxi K通道的调节作用。方法:将携带WNK1和Maxi K目的基因的质粒DNA转染在HEK-293T细胞上,分别应用细胞免疫荧光染色、Western blot观察WNK1对Maxi K在细胞上分布及总蛋白表达水平的影响。结果:免疫荧光染色发现实验组的Maxi K在细胞上的分布明显增多。Western blot结果显示,与对照组相比,实验组1和实验组2的Maxi K总蛋白表达水平均明显升高(P<0.01);与实验组1相比,实验组2的Maxi K总蛋白表达水平亦明显升高(P<0.05)。结论:WNK1能上调Maxi K的总蛋白表达水平,且随着WNK1 DNA剂量的增加,上调作用逐渐增强,显示其上调作用具有剂量依赖性。

Inference on disk-jet connection of MAXI J1836–194 from spectral analysis with the TCAF solution

Galactic transient black hole candidate(BHC)MAXI J1836–194 was discovered on 2011 Aug30,by MAXI/GSC and Swift/BAT.The source activity during this outburst continued for^3 months before entering into the quiescent state.It again became active in March 2012 and continued for another^2 months.In this paper,3-25 keV RXTE/PCA spectra from the 2011 outburst and 0.5-10.0 keV Swift/XRT data during its 2012 outburst are analyzed with the two-component advective flow(TCAF)model based fits files in XSPEC.We calculate the X-ray contributions coming from jets/outflow using a newly developed method based on the deviation of the TCAF model normalization.We also study the correlation between observed radio and estimated jet X-ray fluxes.The correlation indices(b)are found to be 1.79 and 0.61,when the 7.45 GHz Very Large Array(VLA)radio flux is correlated with the total X-ray and jet X-ray fluxes in 3-25 keV range respectively.It has been found that the jet contributes in X-rays up to a maximum of 86%during its 2011 outburst.This makes the BHC MAXI J1836–194 strongly jet dominated during the initial rising phase.

Variation of the inner disk radius during the onset of the 2010 outburst of MAXI J1659–152

Low mass black hole binaries are generally transient sources and spend most of their time in the quiescent state. It is believed that the inner accretion flow in the quiescent state is in the form of advection dominated accretion flow and the cold outer accretion disk is truncated far away from the central black hole. During the onset of an outburst, the disk gradually extends towards the central black hole.However, the observational evidence for this general picture is indirect at best. Here we present the results of a study performed to understand the variation of the inner disk radius during the early phase of an outburst. We investigated the variation of the inner disk radius during the 2010 outburst of the black hole candidate MAXI J1659-152 using the method of simultaneous spectral fitting. We found that the inner edge of the disk is truncated at a large radius in the beginning of the outburst when the source was in the hard state. We found a systematic decrease in the inner disk radius as the outburst progressed. We also estimated an upper limit on the mass of the black hole to be 8.1 ± 2.9 M within the uncertainty of the distance and inclination angle.

Accretion properties of MAXI J1813-095 during its failed outburst in 2018

We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI J1813-095 using Swift,NICER,and NuSTAR observations during its 2018 outburst.The timing behavior of the source is mainly studied by examining NICER light curves in the 0.5−10 keV range.We did not find any signature of quasi-periodic oscillations in the power density spectra of the source.We carry out spectral analysis with a combined disk blackbody&power law model,and physical two-component advective flow(TCAF)model.From the combined disk blackbody&power-law model,we extracted thermal and non-thermal fluxes,photon index and inner disk temperature.We also find evidence for weak reflection in the spectra.We have tested the physical TCAF model on a broadband spectrum from NuSTAR and Swift/XRT.The parameters like mass accretion rates,the size of Compton clouds and the shock strength are extracted.Our result affirms that the source remained in the hard state during the entire outburst which indicates a‘failed’outburst.We estimate the mass of the black hole as 7.4±1.5M⊙from the spectral study with the TCAF model.We apply the LAOR model for the Fe K line emission.From this,the spin parameter of the black hole is ascertained as a^(∗)>0.76.The inclination angle of the system is estimated to be in the range of 28°−45°from the reflection model.We find the source distance to be∼6 kpc.
