The 3rd Fermi GBM Gamma-Ray Burst Catalog: The First Six Years
P. Narayana Bhat, Charles A. Meegan, Andreas von Kienlin +30
Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two gamma-ray bursts (GRB) every three days. Here we present th…
The remarkable warped and twisted gas disk in NGC 3718
Linda S. Sparke, Gustaaf van Moorsel, Ulrich J. Schwarz +1
We have mapped NGC 3718, a nearby bright galaxy in a loose group, and its companion NGC 3729 in the 21cm line of neutral hydrogen. NGC 3718 is a strikingly unusual galaxy with a st…
Geometrical and Physical Properties of Circumbinary Discs in Eccentric Stellar Binaries
Barbara Pichardo, Linda S. Sparke, Luis A. Aguilar
In a previous work (Pichardo et al. 2005), we studied stable configurations for circumstellar discs in eccentric binary systems. We searched for "invariant loops": closed curves (a…
Photometry of Polar-Ring Galaxies
Arturo Godínez-Martínez, Alan M. Watson, Lynn D. Matthews +1
We have obtained photometry in B and R for seven confirmed or probable polar-ring galaxies from the Polar-Ring Catalog of Whitmore et al. (1990). The rings show a range of colors f…
The Photometric and Kinematic Structure of Face-On Disk Galaxies. I. Sample Definition, H-alpha Integral Field Spectroscopy, and HI Line-Widths
David R. Andersen, Matthew A. Bershady, Linda S. Sparke +5
We present a survey of the photometric and kinematic properties of 39 nearby, nearly face-on disk galaxies. Our approach exploits echelle-resolution integral-field spectroscopy of…
Stellar kinematics for the central spheroid in the Polar Disk Galaxy NGC4650A
E. Iodice, M. Arnaboldi, R. P. Saglia +7
We have obtained high angular resolution, high signal-to-noise spectra of the Calcium triplet absorption lines on the photometric axes of the stellar spheroid in the polar disk gal…
