Coronagraph Workshop papers (2007)

Traub, Wesley A., Abe, Lyu, Angel, Roger, Arenberg, Jon, Balasubramanian, Bala, Baudoz, Pierre, ...

This volume contains the written contributions corresponding to the oral presentations of about 45 authors at the Coronagraph Workshop 2006.

The Color Selection of Quasars from Redshifts 5 to 10: Cloning and Discovery (2005)

Chiu, Kuenley, Zheng, Wei, Schneider, Donald P., Glazebrook, Karl, Iye, Masanori, Kashikawa, Nobunari, ...

We present simulations of quasar colors, magnitudes, and numbers at redshifts 54.7 quasars increases by a factor of 3X by extending 0.7 i-magnitudes deeper than the SDSS spectroscopic survey limit of...

A Redshift z=5.4 Lyman alpha Emitting Galaxy with Linear Morphology in the GRAPES/UDF Field (2004)

Rhoads, James E., Panagia, Nino, Windhorst, Rogier A., Malhotra, Sangeeta, Pirzkal, Norbert, Xu, Chun, ...

We have discovered an extended Lyman alpha plume associated with a compact source at redshift 5.4 in slitless spectroscopic data from the Grism ACS Program for Extragalactic Science (GRAPES) project....

Type Ia Supernova Discoveries at z>1 From the Hubble Space Telescope: Evidence for Past Deceleration and Constraints on Dark Energy Evolution (2004)

Riess, Adam G., Strolger, Louis-Gregory, Tonry, John, Casertano, Stefano, Ferguson, Henry C., Mobasher, Bahram, ...

We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to provide the first conclusive evidence for cosmic deceleration that preceded the current...

Three Lyman-alpha Emitters at z approx 6: Early GMOS/Gemini Data from the GLARE Project (2003)

Stanway, Elizabeth R., Glazebrook, Karl, Bunker, Andrew J., Abraham, Roberto G., Hook, Isobel, Rhoads, James, ...

We report spectroscopic detection of three z~6 Lyman-alpha emitting galaxies, in the vicinity of the Hubble Ultra Deep Field, from the early data of the Gemini Lyman-$\alpha$ at Reionisation Era...

Identification of Type Ia Supernovae at Redshift 1.3 and Beyond with the Advanced Camera for Surveys on HST (2003)

Riess, Adam G., Strolger, Louis-Gregory, Tonry, John, Tsvetanov, Zlatan, Casertano, Stefano, Ferguson, Henry C., ...

We present discoveries of SNe Ia at z > 1 and the photometric diagnostic used to discriminate them from other types of SNe detected during the GOODS Hubble Space Telescope Treasury program with the...

A Catalog of Broad Absorption Line Quasars from the Sloan Digital Sky Survey Early Data Release (2003)

Reichard, Timothy A., Richards, Gordon T., Schneider, Donald P., Hall, Patrick B., Tolea, Alin, Krolik, Julian H., ...

We present a catalog of 224 broad absorption line quasars (BALQSOs) from the Sloan Digital Sky Survey's Early Data Release Quasar Catalog, including a relatively complete and homogeneous subsample of...

Broad Absorption Line Quasars in the Early Data Release from the Sloan Digital Sky Survey (2002)

Tolea, Alin, Krolik, Julian H., Tsvetanov, Zlatan

A new broad absorption line quasar (BAL) sample is derived from the first data released by the Sloan Digital Sky Survey. With 116 objects, it is the largest BAL sample yet assembled. Over the...

Sloan Digital Sky Survey: Early data release (2002)

Stoughton, Chirs, Lupton, Rpbert H., Bernardi, Mariangela, Blanton, Michael R., Burles, Scott, Castander, Francsico J., ...

The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of 10 6 galaxies, 100,000...

Optimal multihump filter for photometric redshifts (2001)

Budavari, Tamas, Szalay, Alexander S., Csabai, Istvan, Connolly, Andrew J., Tsvetanov, Zlatan

We propose a novel type filter for multicolor imaging to improve on the photometric redshift estimation of galaxies. An extra filter - specific to a certain photometric system - may be utilized with...

WFPC2 Images of the Central Regions of Early-Type Galaxies - I. The Data (2001)

Rest, Armin, Jaffe, Walter, Tran, Hien, Tsvetanov, Zlatan, Ford, Holland C., ...

We present high resolution R-band images of the central regions of 67 early-type galaxies obtained with the Wide Field and Planetary Camera 2 (WFPC2) aboard the Hubble Space Telescope (HST). Our...

The Nuclear Disk in M87: A Review (1998)

Ford, Holland, Tsvetanov, Zlatan

Three sets of HST+COSTAR FOS and FOC observations provide strong evidence that the nuclear disk in M87 is in Keplerian rotation around a black hole with a mass of (2 - 3)x10^9 M_sol. A deep (6...
