Abstract Two dwarf galaxies, WOC2017-07 and PGC 704814, located in the vicinity of nearby luminous spiral galaxy NGC 253 were observed with Advanced Camera for Surveys on Hubble Space Telescope. Their distances 3.62 ± 0.18 Mpc 3.66 derived using tip red giant branch method. These are consistent galaxies being members group. Based radial velocities projected separations seven assumed companions,...

The high density medium that characterizes the central regions of starburst galaxies and its power to accelerate particles up to relativistic energies make these objects good candidates as γ-rays sources. In this paper, a self-consistent model of the multifrequency emission of the starburst galaxy NGC 253, from radio to gamma-rays, is presented. The model is in agreement with all current measur...

The study extends research on the impact of commodity futures investments on portfolio performance by incorporating levered futures directly into the optimization problem. Differences in portfolio performance between fully collateralized and levered futures arise primarily in the presence of investment constraints. The attractiveness of portfolios is also affected by differences in commodity in...

We report the results of a deep spatial, spectral, and timing analysis of ROSAT HRI and PSPC observations of the edge-on starburst galaxy NGC 253. In this first paper, point-like X-ray sources detected within the galaxy and in the field are discussed. The sources are characterized by their X-ray properties (including comparisons with results from the Einstein and ASCA satellites), by correlatio...

Polypyridyl based ruthenium(II) complexes, [Ru(bpy)2(furphen)](PF6)2 (1) and [Ru(bpy)2(imiphen)](PF6)2 (2) {furphen: 2-(furan-2-yl)-1H-imidazo[4,5-f][1,10]phenanthroline and imiphen: 2-(1H-imidazol-2-yl)-1H-imidazo[4,5-f][1,10]phenanthroline} were synthesized and characterized by ESI-MS, NMR, UV-Visible and fluorescence spectroscopic techniques. The interaction of Ru(II) complexes with calf-thy...
