Abstract Orbital‐angular‐momentum (OAM) beams‐based interferometer has been found various applications in high‐precision metrology. However, most of its reported to date are limited 1D ones, and the simultaneous measurements for multidimensional displacement have rarely explored. Here an angular momentum superposition is first proposed demonstrated, which phases‐changes induced by rotational linear displacements, independently carried (SOAMS) beam containing different spin orbital momenta,...
We perform correlation and periodicity search analyses on long-term multi-band light curves of the FSRQ 1510-089 observed by space-based Fermi--Large Area Telescope in gamma-rays, SMARTS Steward Observatory telescopes optical near-infrared (NIR) 13.7 m radio telescope Metsahovi Radio between 2008 2018. The z-transform discrete function method is applied to study possible time lags among these multi band curves. Among all pairs wavelengths, gamma-ray vs. optical/NIR NIR correlations show zero...
X-ray Timing and Polarization (XTP) satellite, by using focusing optics advanced detector technology, is dedicated to the study of Black Hole, Neutron Star, Quark Star physics under extreme gravity, density magnetism. With a detection area ~1 square meter combination various types telescopes, XTP expected make most sensitive temporal polarization observations with good energy resolution in 1-30 keV. We present recent overview on segmented glass for Telescope. This work looking improvement...
We analyze the jet-disk coupling for different subsamples from a complete hard X-ray Seyfert sample to study indices and their relation accretion rate. The results are: (1) power-law index ranges nearly unity (linear correlation) radio-loud Seyferts significantly less than radio-quiet ones. This declining trend of also holds larger sources compact ones; (2) with intermediate high rate (Eddington ratio $\lambda\sim$ 0.001 0.3) show linear coupling, but it shallows near super Eddington...
Quantum sensing with cold atoms is attracting more and attention in the research frontier of quantum technologies. Isotropic laser cooling serves as a promising platform for this area its many advantages include compactness, robustness, not requiring fine-tuning optical alignment or magnetic field, which are particularly suitable field space applications. We have designed demonstrated special form isotropic system that specifically tailored purpose sensing. In particular, diffused generated...
We studied the relation of accretion-jet power and disk luminosity, especially jet efficiencies radiative for different accretion disks as well black hole (BH) spin, in order to explore origin radio emission X-ray binaries (BHXBs). found that efficiency increases more rapidly (efficient) than nearly constant thin component high regime, which could account steep track ($\mu>1$) observed luminosity relations ($L_{\rm R}\propto L_{\rm X}^{\mu}$), but may not be able explain standard...
Two dozens of radio loud active galactic nuclei (AGNs) have been observed with Urumqi 25 m telescope in order to search for intra-day variability (IDV). The target sources are blazars (namely flat spectrum quasars and BL Lac objects) which mostly selected from the observing list RadioAstron AGN monitoring campaigns. observations were carried out at 4.8 GHz two sessions 8–12 February 2014 7–9 March respectively. We report data reduction first results observations. show that majority exhibit...

Analyzing single-dish and VLBI radio, as well \textit{Fermi}-LAT $\gamma$-ray observations, we explained the three major flares in light curve of FSRQ J1048+7143 with spin--orbit precession dominant mass black hole a supermassive binary system. Here, report on detection fourth flare from J1048+7143, appearing time interval which was predicted our previous work. Including this new flare, constrained ratio into narrow range $0.062<q<0.088$, consequently were able to further constrain...
