	Synchronous X-ray/Optical QPOs from the Black Hole LMXB MAXI J1820+070 期刊论文 OAI收割 Monthly Notices of the Royal Astronomical Society, 2021 作者: HXMT \| 收藏 \| 浏览/下载：52/0 \| 提交时间：2022/02/08 black hole physics Low Mass X-ray Binaries accretion accretion discs stars: individual (MAXI J1820+070) Astrophysics - High Energy Astrophysical Phenomena Abstract: We present high-speed optical photometry from SAAO and SALT on the black hole LMXB MAXI J1820+070 (ASSASN-18ey), some of it simultaneous with NICER, Swift and Insight-HXMT X-ray coverage. We detect optical Quasi-Periodic Oscillations (QPOs) that move to higher frequencies as the outburst progresses, tracking both the frequency and evolution of similar X-ray QPOs previously reported. Correlated X-ray/optical data reveal a complex pattern of lags, including an anti-correlation and a sub-second lag that evolve over the first few weeks of outburst. They also show correlated components separated by a lag equal to the QPO period roughly centered on zero lag, implying that the inter-band variability is strongly and consistently affected by these QPOs at a constant phase lag of roughly ±Ю The synchronisation of X-ray and optical QPOs indicates that they must be produced in regions physically very close to each other we thus propose that they can be explained by a precessing jet model, based on analogies with V404 Cyg and MAXI J1348-630.

	Transmission properties of multiband fss based on fractal elements (EI CONFERENCE) 会议论文 OAI收割 2010 9th International Symposium on Antennas Propagation and EM Theory, ISAPE 2010, November 29, 2010 - December 2, 2010, Guangzhou, China 作者: Gao J. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 Self-similar fractal elements that has multiband properties can be advantageously exploited to design simple multiband FSS on single screen. In this paper fractal Y aperture FSS has been designed using recursive technology and the periodic method of moments(PMoM) is employed to characterize the transmission properties of FSS as band-pass filters. The frequency response to the structure parameters when electromagnetic wave incident with different angles and polarizations is discussed and the numerical analysis show good correlation to the measured results. 2010 IEEE.
