The haloes and environments of nearby galaxies (HERON) -- III. A 45 kpc spiral structure in the GLSB galaxy UGC 4599
Aleksandr V. Mosenkov, R. Michael Rich, Michael Fusco +10
We use a 0.7-m telescope in the framework of the Halos and Environments of Nearby Galaxies (HERON) survey to probe low surface brightness structures in nearby galaxies. One of our…
Reverberation Mapping of the Kepler-Field AGN KA1858+4850
Liuyi Pei, Aaron J. Barth, Greg S. Aldering +40
KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapp…
G2C2 II: Integrated colour-metallicity relations for Galactic Globular Clusters in SDSS passbands
Joachim Vanderbeke, Michael J. West, Roberto De Propris +8
We use our integrated SDSS photometry for 96 globular clusters in and , as well as and photometry for a subset of 56 clusters, to derive the integrated colour-metall…
G2C2 I: Homogeneous SDSS photometry for Galactic GCs
Joachim Vanderbeke, Michael J. West, Roberto De Propris +8
We present and aperture photometry for 96 Galactic Globular Clusters, making this the largest homogeneous catalog of photometry for these objects in the SDSS…
On Modified Dispersion Relations and the Chandrasekhar Mass Limit
Michael Gregg, Seth A. Major
Modified dispersion relations from effective field theory are shown to alter the Chandrasekhar mass limit. At exceptionally high densities, the modifications affect the pressure of…
A Survey of z>5.7 Quasars in the Sloan Digital Sky Survey II: Discovery of Three Additional Quasars at z>6
Xiaohui Fan, Michael A. Strauss, Donald P. Schneider +14
We present the discovery of three new quasars at z>6 in 1300 deg^2 of SDSS imaging data, J114816.64+525150.3 (z=6.43), J104845.05+463718.3 (z=6.23) and J163033.90+401209.6 (z=6.05)…
