We report on the detection with the MAGIC telescopes of very high energy (VHE) γ-rays from IC 310, a head-tail radio galaxy in the Perseus galaxy cluster, observed during the interval 2008 November to 2010 February. The Fermi satellite has also detected this galaxy. The source is detected by MAGIC at a high statistical significance of 7.6σ in 20.6

We have investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imaging Magnetograph eXperiment (IMaX) on board the balloon-borne solar observatory SUNRISE. We find that granules frequently show substructure in the form of lanes composed

g' and z' photometric time series for the last ~1.6hrs of the transit of KOI 806.2 observed with the Gran Telescopio Canarias at Observatorio del Roque de los Muchachos on the island of La Palma, Spain. The observations occurred on JD 2455740, revealing a transit timing variation of -103.5+/-6.9 minutes. The raw fits files were bias and flat field

This article presents a theoretical framework for the evolution of the light-element nuclides in the Galactic disk. By understanding this evolution correctly, we can reliably obtain the primordial abundances of the nuclides D, 4He, and 7Li. We use two key assumptions, those of (1) infall of metal-poor gas to the disk at an increasing rate and (2)

From published catalogs, basic physical properties including diameters, masses, and neutral hydrogen contents of spiral galaxies have been studied as a function of the arm class. The results indicate that galaxies with well-defined arms have longer scale-lengths (a difference comparable in the red to that in the blue) and are more massive (in both
