Received ; accepted – 2 – ABSTRACT Two ASCA observations were made of two ultra-luminous compact X-ray sources Source 2 showed a 0.5–10 keV luminosity of 6 × 10 39 ergs s −1 (assuming a distance of 4.0 Mpc), and a hard power-law spectrum of photon index ∼ 1.4. As already reported, Source 1 was ∼ 3 times brighter on that occasion, and exhibited a soft spectrum represented by a multi-color disk m...

The Seyfert 2 galaxy Mrk 1210 was found to exhibit a flat hard X-ray component by ASCA, although ASCA could not distinguish whether it is an absorbed direct component or a reflected one. We then observed Mrk 1210 with BeppoSAX, and found that the X-ray spectral properties are quite different from those of ASCA, as have been confirmed with XMM-Newton; the flux is significantly higher than that i...

We develop two N = 2 superfield formulations of free equations of motion for the joint model of all D = 4 massless higher-superspin fields in generating form. The explicit Osp(2|4) supersymmetry is achieved without exploiting the harmonic superspace, and with adding no auxiliary component fields to those of N = 1 superfields. The formulations are developed in two different Osp(2|4) homogeneous ...

But these experiments [2] will not give us any information about the dependence or independence of the two factors, namely study habit and home environment. In such cases, we resort to Factorial ANOVA which not only helps us to study the effect of two or more factors but also gives information about their dependence or independence in the same experiment. There are many types of factorial desig...

We analyse ASCA x-ray data and Whipple γ-ray data from the blazars Mkn421 and Mkn501 for short-timescale variability. We find no evidence for statistically significant (> 3σ) variability in these data, in either source, on timescales of less than ∼ 10 minutes.

Virginia to indicate their most common and most challenging ethical dilemmas are presented. Ninetytwo school counselors reported that the most common and challenging ethical dilemmas included those involving student confidentiality, dual relationship with faculty, parental rights, and acting on information of student danger to themselves or others. Results are reported for differences in academ...

We report the BeppoSAX detection of a hard X-ray excess in the X-ray spectrum of the classical high-ionization Seyfert 2 galaxy Tol 0109–383. The X-ray emission of this source observed below 7 keV is dominated by reflection from both cold and ionized gas, as seen in the ASCA data. The excess hard X-ray emission is presumably due to the central source absorbed by an optically thick obscuring tor...

RXTE/ASM observations of PSR B1259−63 near the 1997 periastron passage find no emission brighter than ∼10 times that detected by ASCA during the 1994 periastron encounter, demonstrating that the pulsar is unlikely to have undergone even brief episodes of accretion.
