Correlated X-ray/Optical Variability in the Quasar MR2251-178
P. Arévalo, P. Uttley, S. Kaspi +3
Emission from Active Galactic Nuclei is known to vary strongly over time over a wide energy band, but the origin of the variability and especially of the inter-band correlations is…
Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
An infrared study of the double nucleus in NGC3256
P. Lira, V. Gonzalez-Corvalan, M. Ward +1
We present new resolved near and mid-IR imaging and N-band spectroscopy of the two nuclei in the merger system NGCA3256, the most IR luminous galaxy in the nearby universe. The res…
Ly-alpha Emission-Line Galaxies at z = 3.1 in the Extended Chandra Deep Field South
C. Gronwall, R. Ciardullo, T. Hickey +13
We describe the results of an extremely deep, 0.28 deg^2 survey for z = 3.1 Ly-alpha emission-line galaxies in the Extended Chandra Deep Field South. By using a narrow-band 5000 An…
The rest-frame optical luminosity functions of galaxies at 2<z<3.5
Danilo Marchesini, Pieter van Dokkum, Ryan Quadri +7
We present the rest-frame optical (B, V, and R band) luminosity functions (LFs) of galaxies at 2<z<3.5, measured from a K-selected sample constructed from the deep NIR MUSYC, the u…
