The black-hole binary LMC X–3 is known to be variable on time scales of days to years. We investigate X-ray and ultraviolet variability in the system as a function of the 1.7 day binary phase using a 6.4 day observation with the Rossi X-ray Timing Explorer (RXTE) from December 1998. An abrupt 14% flux decrease, lasting nearly an entire orbit, is followed by a return to previous flux levels. Thi...

Abstract The reflex motion and distortion of the Milky Way (MW) halo caused by infall a massive Large Magellanic Cloud (LMC) has been demonstrated to result in an excess orbital poles dark matter particles toward LMC pole. This was suggested help explain observed preference MW satellite galaxies coorbit along Vast Polar Structure (VPOS). We test this idea correcting positions velocities satelli...

Abstract The zero point of the reddening toward Large Magellanic Cloud (LMC) has been subject some dispute. Its uncertainty propagates as a systematic error for methods that measure extragalactic distance scale through knowledge absolute extinction LMC stars. In an effort to resolve this issue, we used three different calibrate most widely metric predict extinction, intrinsic color red clump, (...

We present the results from an analysis of Hubble Space Telescope High Resolution Camera data for the Large Magellanic Cloud microlensing event MACHO-LMC-5. By determining the parallax and proper motion of this object we find that the lens is an M dwarf star at a distance of 578 −53pc with a proper motion of 21.39±0.04 mas/yr. Based on the kinematics and location of this star it more likely to ...

Little Man Computer (LMC) Paradigm, a simple representation of a real computer system with pedagogical purposes, was firstly presented in 1965. It follows von Neumann’s Architectural Model and uses a simplified instruction set. Since then, many simulators have been developed based on this Paradigm. Mainly, those simulators have been designed to be used by undergraduate students in Computer Arch...

We present RXTE observations of LMC X–2 obtained during a five-day interval in 1997 December, during which the source was radiating at a mean intensity near the Eddington limit, and strongly variable on timescales of seconds to hours. The shapes of the X-ray color-color and hardness-intensity diagrams during the observations, the presence of VLFN and HFN in the power spectra, and the high intri...

BACKGROUND Prolongation of action potential duration (APD), increased spatial APD dispersion, and triangulation are major factors promoting drug-induced ventricular arrhythmia. Preclinical identification of HERG/IKr-blocking drugs and their pro-arrhythmic potential, however, remains a challenge. We hypothesize that transgenic long-QT type 1 (LQT1) rabbits lacking repolarizing IKs current may he...

purpose: to determine the indications for and surgical techniques of corneal transplantation at labbafinejad medical center (lmc) from 2004 to 2007. methods: in this descriptive study, records of 756 patients who had undergone corneal transplantation from october 2004 to october 2007 were reviewed. results: overall, 504 male (64.9%) and 272 female (35.1%) subjects with mean age of 41.29±21.25 (...

We use the APOSTLE $\Lambda$CDM cosmological hydrodynamical simulations of Local Group to study recent accretion massive satellites into halo Milky Way (MW)-sized galaxies. These systems are selected be close analogues Large Magellanic Cloud (LMC), most satellite MW. The allow us address, in a context, impact Clouds on MW, including contribution MW population, and constraints placed Galactic po...

Context. The structural parameters of the disk of the Large Magellanic Cloud (LMC) are estimated. Aims. We used the JH photometric data of red clump (RC) stars from the Magellanic Cloud Point Source Catalog (MCPSC) obtained from the InfraRed Survey Facility (IRSF) to estimate the structural parameters of the LMC disk, such as the inclination, i, and the position angle of the line of nodes (PAlo...
