Frame-dragging, disk warping, jet precessing, and dipped X-ray lightcurve of Sw J1644+57
Frame-dragging disk warping jet precessing dipped X-ray lightcurve Sw J1644+57
2012/2/23
The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events, the...
A double component in GRB 090618: a proto-black hole and a genuinely long GRB
double component GRB 090618 proto-black hole GRB
2012/2/23
The joint X and gamma-ray observations of GRB 090618 by a large number of satellites offer an unprecedented possibility of testing crucial aspects of theoretical models. In particular, it allows us to...
Holographic Dark Energy Characterized by the Total Comoving Horizon and Insights to Cosmological Constant and Coincidence Problem
Holographic Dark Energy the Total Comoving Horizon Insights Cosmological Constant Coincidence Problem
2012/2/21
The observed acceleration of the present universe is shown to be well explained by the holographic dark energy characterized by the total comoving horizon of the universe ($\eta$HDE). It is of interes...
Probing dark energy beyond $z=2$ with CODEX
Probing dark energy CODEX cosmological redshift
2012/2/21
Precision measurements of nature's fundamental couplings and a first measurement of the cosmological redshift drift are two of the key targets for future high-resolution ultra-stable spectrographs suc...
Future constraints on variations of the fine structure constant from combined CMB and weak lensing measurements
Future constraints variations fine structure constant combined CMB weak lensing measurements
2012/2/21
We forecast the ability of future CMB and galaxy lensing surveys to constrain variations of the fine structure constant. We found that lensing data, as those expected from satellite experiments as Euc...
The XMM Cluster Survey: The Stellar Mass Assembly of Fossil Galaxies
The XMM Cluster Survey Stellar Mass Fossil Galaxies Cosmology and Extragalactic Astrophysics
2012/2/21
This paper presents both the result of a search for fossil systems within the XMM Cluster Survey and the Sloan Digital Sky Survey and the results of a study of the stellar mass assembly and stellar po...
Axino dark matter and baryon number asymmetry from Q-ball decay in gauge mediation
Axino dark matter baryon number asymmetry Q-ball decay gauge mediation
2012/2/21
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into axinos to account fo...
Brightness and Fluctuation of the Mid-Infrared Sky from AKARI Observations towards the North Ecliptic Pole
Brightness Fluctuation Mid-Infrared Sky AKARI Observations the North Ecliptic Pole
2012/2/21
We present the smoothness of the mid-infrared sky from observations by the Japanese infrared astronomical satellite AKARI. AKARI monitored the north ecliptic pole (NEP) during its cold phase with nine...
Extending the M_(bh)-sigma diagram with dense nuclear star clusters
Extending the M_(bh)-sigma diagram dense nuclear star clusters
2012/2/21
Abridged: Four new nuclear star cluster masses, M_nc, plus seven upper limits, are provided for galaxies with previously determined black hole masses, M_bh. Together with a sample of 64 galaxies with ...
Prospects for early localization of gravitational-wave signals from compact binary coalescences with advanced detectors
Prospects early localization gravitational-wave signals compact binary coalescences advanced detectors
2012/2/21
A leading candidate source of detectable gravitational waves is the inspiral and merger of pairs of stellar-mass compact objects. The advanced LIGO and advanced Virgo detectors will allow scientists t...
Theory of magnetic reconnection in solar and astrophysical plasmas
Theory magnetic reconnection solar astrophysical plasmas
2012/2/23
Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this article we prese...
Detection of Ks-band Thermal Emission from WASP-3b
planetary systems Ks-band Thermal Emission WASP-3b
2012/2/23
We report the detection of thermal emission from the hot Jupiter WASP-3b in the KS band, using a newly developed guiding scheme for the WIRC instrument at the Palomar Hale 200in telescope. Our new gui...
星球的存在是由两种简单的冷热物质力量的对抗作用为基础，表现为物质层次旋进包压的形式。冷热物质力量的对抗是星球本身的自转和星球之间的公转原动力，也是星球从产生、发展到消亡过程演变的根源。
本人已用推迟引力成功求解水星近日点进动获得与爱因斯坦广义相对论完全相同的结果，与观测结果符合。在上述工作的基础上，本文专门研究了以光速或准光速飞行的粒子与作低速运动的星体、粒子受到的引力的区别，给出了在弱场中以光速或准光速飞行的粒子受到的引力的表达式，并给出在弱场中以任意速度飞行的粒子受到的引力的通用表达式。根据此弱场中以光速飞行粒子受到的引力表达式，计算出由瑞士日内瓦CERN发射并飞行至意大利G...
