A Vigorous Explorer Program (2009)

Elvis, Martin, Beasley, Matthew, Brissenden, Roger, Chakrabarti, Supriya, Cherry, Michael, Devlin, Mark, ...

Explorers have made breakthroughs in many fields of astrophysics. The science from both these missions contributed to three Nobel Prizes - Giacconi (2002), Mather, and Smoot (2006). Explorers have:...

First Steps in Direct Imaging of Planetary Systems Like our Own: The Science Potential of 2-m Class Optical Space Telescopes (2007)

Stapelfeldt, Karl, Trauger, John, Traub, Weslay, Clampin, Mark, Oegerle, William, Wiseman, Jennifer, ...

We summarize the scientific potential of high contrast optical space imaging for studies of extrasolar planets, debris disks, and planet formation. The unique scientific capabilities offered by a 2-m...

Abell 2111: An Optical and Radio Study of the Richest Butcher-Oemler Cluster (2006)

Miller, Neal A., Oegerle, William, Hill, John

We present an in-depth analysis of the Butcher-Oemler cluster A2111, including new optical spectroscopy plus a deep Very Large Array (VLA) radio continuum observation. These are combined with optical...

Intrinsic Absorption in the Spectrum of NGC 7469: Simultaneous Chandra, FUSE, and STIS Observations (2005)

Scott, Jennifer E., Kriss, Gerard A., Lee, Julia C., Quijano, Jessica Kim, Brotherton, Michael, Canizares, Claude R., ...

We present simultaneous X-ray, far-ultraviolet, and near-ultraviolet spectra of the Seyfert 1 galaxy NGC 7469 obtained with the Chandra X-Ray Observatory, the Far Ultraviolet Spectroscopic Explorer,...

Quasars and the Big Blue Bump (2004)

Shang, Zhaohui, Brotherton, Michael S., Green, Richard F., Kriss, Gerard A., Scott, Jennifer, Quijano, Jessica Kim, ...

We investigate the ultraviolet-to-optical spectral energy distributions (SEDs) of 17 active galactic nuclei (AGNs) using quasi-simultaneous spectrophotometry spanning 900-9000 Angstrom (rest frame)....

Intrinsic Absorption in the Spectrum of Mrk 279: Simultaneous Chandra, FUSE, and STIS Observations (2004)

Scott, Jennifer E., Kriss, Gerard A., Lee, Julia C., Arav, Nahum, Ogle, Patrick, Roraback, Kenneth, ...

We present a study of the intrinsic X-ray and far-ultraviolet absorption in the Seyfert 1.5 galaxy Markarian 279 using simultaneous observations from the Chandra X-ray Observatory, the Space...

An I-Band-Selected Sample of Radio-Emitting Quasars: Evidence for a Large Population of Red Quasars (2003)

White, Richard L., Helfand, David J., Becker, Robert H., Gregg, Michael D., Postman, Marc, Lauer, Tod R., ...

We present a new sample of 35 quasars selected from the FIRST radio survey and the Deeprange I-band survey (Postman et al. 1998, 2002). A comparison with the FIRST Bright Quasar survey samples...

The KPNO/Deeprange Distant Cluster Survey: I. The Catalog & the Space Density of Intermediate Redshift Clusters (2002)

Postman, Marc, Lauer, Tod R., Oegerle, William, Donahue, Megan

We have conducted an automated search for galaxy clusters within a contiguous 16 square degree I-band survey in the north Galactic hemisphere. A matched filter detection algorithm identifies 444...

Observational Constraints on Higher Order Clustering up to $z\simeq 1 (2000)

Szapudi, István, Postman, Marc, Lauer, Tod R., Oegerle, William

Constraints on the validity of the hierarchical gravitational instability theory and the evolution of biasing are presented based upon measurements of higher order clustering statistics in the...

Clustering at High Redshift: Precise Constraints from a Deep, Wide Area Survey (1998)

Postman, Marc, Lauer, Tod R., Szapudi, Istvan, Oegerle, William

We present constraints on the evolution of large-scale structure from a catalog of 710,000 galaxies with I_AB

Clustering at High Redshift: Observational Constraints from a Deep, Wide Area Survey (1998)

Marc Postman, A. Fontana, E. Giallongo, Tod R. Lauer, William Oegerle

. We present constraints on the evolution of large-scale structure from a catalog of 710,000 galaxies with I AB 24. The catalog is derived from a CCD imaging survey of a contiguous 4 ffi \Theta 4 ffi...
