It was recently reported that the black hole candidate X-ray binary MAXI J1659-152 has faded to an X-ray flux (0.5-10 keV) of 3.0e-13 ergs cm-2 s-1 (ATel #3506...
We report on a pointed RXTE/PCA observation of the transient source MAXI J1659-152 (Atel #2873,#2874,#2875,#2877,#2880 GCN #11296,#11299, #11307 - initially...
We observed the optical counterpart of MAXI J1836-194 (Negoro et al., ATel#3611; Kennea et al., ATel#3613) with the 82cm IAC80 telescope at the Observatorio del...

Mean field exact solutions showing charge density wave crossover at low fillings in the fractional quantum Hall regime
A general analytical framework for the determination of the mean field states at arbitrary rational filling factors for the 2DEG in FQHE regime is given. Its...
Measurement of Galactic Logarithmic Spiral Arm Pitch Angle Using Two-Dimensional Fast Fourier Transform Decomposition
A logarithmic spiral is a prominent feature appearing in a majority of observed galaxies. This feature has long been associated with the traditional Hubble...
