A simple formula to read out the weak value from the wave function of the measuring device after the postselection with the initial Gaussian profile is proposed. We apply this formula for the weak value to the classical experiment of the realization…

Weak Value in Wave Function of Detector

A simple formula to read out the weak value from the wave function of the measuring device after the postselection with the initial Gaussian profile …

The high-statistics map of the X-ray hardness ratio obtained from long-time (∼100 ks) observations of A 85 with Suzaku revealed a large peak on the east side of the subcluster. From the spectral fittings, a comparable result was obtained. A detailed…

Suzaku Observations of the Merging Cluster Abell 85: Temperature Map …

To investigate the present situation of the merging in the southern outer region of Abell 85, we carried out long (~100 ks) observations with Suzaku,…

We have used the statistically significant sample of 179 protoclusters from the HSC survey (Toshikawa et al., 2017). to investigate the spatial correlation between the protoclusters and quasars at z∼4. Note that this sample is around 10 times as lar…

Luminous Quasars Do Not Live in the Most Overdense Regions of Galaxie…

We present the cross-correlation between 151 luminous quasars ($M_{ \mathrm{UV}} < -26$) and 179 protocluster candidates at $z \sim 3.8$, extracted f…

With the results of our proper-motion measurements, we now consider the motion of the H2O maser source in NGC 281 West with respect to the Galactic plane. At the position of NGC 281 West, the Galactic plane lies almost parallel to the east-west (RA)…

Absolute Proper Motions of H2O Masers Away from the Galactic Plane …

We report on absolute proper-motion measurements of an H2O maser source in the NGC 281 West molecular cloud, which is located ~320 pc above the Galac…
