XMM-Newton Detection of Hot Gas in the Eskimo Nebula: Shocked Stellar Wind or Collimated Outflows?
M. A. Guerrero, Y. -H. Chu, R. A. Gruendl +1
The Eskimo Nebula (NGC 2392) is a double-shell planetary nebula (PN) known for the exceptionally large expansion velocity of its inner shell, ~90 km/s, and the existence of a fast…
alpha-, r-, and s-process element trends in the Galactic thin and thick disks
T. Bensby, S. Feltzing, I. Lundström +1
From a detailed elemental abundance analysis of 102 F and G dwarf stars we present abundance trends in the Galactic thin and thick disks for 14 elements (O, Na, Mg, Al, Si, Ca, Ti,…
Discovery of Irradiation Induced Variations in the Light Curve of the Classical Nova Cygni 2001 No.2 (V2275 Cyg)
S. Balman, A. Yilmaz, A. Retter +3
We present the CCD photometry, light curve and time series analysis of the classical nova V2275 Cyg (N Cyg 2001 No.2). The source was observed for 14 nights in total using an R fil…
The Zone of Avoidance: Optical Compared to Near-Infrared Searches
Renee C. Kraan-Korteweg, Thomas Jarrett
Galaxies uncovered in the Zone of Avoidance (ZOA) with deep optical searches are compared to the distribution of objects in the 2MASS Extended Source Catalog (2MASX). While the gal…
Keck Adaptive Optics Imaging of 0.5<z<1 Field Galaxies from the Hubble Space Telescope Archive
Eric Steinbring, A. J. Metevier, Stuart A. Norton +6
We have employed natural guide star adaptive optics (AO) on the Keck II telescope to obtain near-infrared (H and K') images of three field galaxies, each of redshift greater than 0…
The Clustering of AGN in the Sloan Digital Sky Survey
David A. Wake, Christopher J. Miller, Tiziana Di Matteo +6
We present the two--point correlation function (2PCF) of narrow-line active galactic nuclei (AGN) selected within the First Data Release of the Sloan Digital Sky Survey. Using a sa…
