Lyα Emission-Line Galaxies at z = 3.1 in the Extended Chandra Deep Field-South
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 Anstrom filter and
PLANETARY NEBULAE AS STANDARD CANDLES. XII. CONNECTING THE POPULATION I AND POPULATION II DISTANCE SCALES
We report the results of [O III] λ5007 surveys for planetary nebulae (PNe) in six galaxies: NGC 2403, NGC 3115, NGC 3351, NGC 3627, NGC 4258, and NGC 5866. Using on-band/off-band [O III] λ5007
Planetary Nebulae as Standard Candles. XI. Application to Spiral Galaxies
We report the results of an [O III] λ5007 survey for planetary nebulae (PNs) in three spiral galaxies: M101 (NGC 5457), M51 (NGC 5194/5195), and M96 (NGC 3368). By comparing on-band/off-band [O III]
Planetary nebulae as standard candles. II. The calibration in M31 and its companions
The results of a PN survey of M31's bulge are reported. A total of 429 PNs were detected, of which 104 are members of a statistically complete and homogeneous sample covering the top 2.5 mag of the
Lyα-Emitting Galaxies at z = 3.1: L* Progenitors Experiencing Rapid Star Formation*
We studied the clustering properties and multiwavelength spectral energy distributions of a complete sample of 162 Lyα-emitting (LAE) galaxies at z 3.1 discovered in deep narrowband MUSYC imaging of
A HUBBLE SPACE TELESCOPE Survey for Resolved Companions of Planetary Nebula Nuclei
We report the results of a Hubble Space Telescope "snapshot" survey aimed at finding resolved binary companions of the central stars of Galactic planetary nebulae (PNe). Using the the Wide Field and
The physical nature of Lyα-emitting galaxies at z = 3.1
We selected 40 candidate Lyα-emitting galaxies (LAEs) at z 3.1 with observed-frame equivalent widths greater than 150 A and inferred emission-line fluxes above 2.5 × 10-17 ergs cm-2 s-1 from deep
The High-Z Supernova Search: Measuring Cosmic Deceleration and Global Curvature of the Universe Usin
The High-Z Supernova Search is an international collaboration to discover and monitor Type Ia supernovae (SNe Ia) at z > 0.2 with the aim of measuring cosmic deceleration and global curvature. Our
Lyα-EMITTING GALAXIES AT z = 2.1 IN ECDF-S: BUILDING BLOCKS OF TYPICAL PRESENT-DAY GALAXIES?*
We discovered a sample of 250 Ly{alpha} emitting (LAE) galaxies at z {approx_equal} 2.1 in an ultra-deep 3727 A narrow-band MUSYC image of the Extended Chandra Deep Field-South. The LAEs were
The planetary nebula system and dynamics of NGC 5128. I - Planetary nebulae as standard candles
We present the result of a planetary nebula (PN) survey of the nearby giant elliptical galaxy NGC 5128 performed with CCD cameras at the prime focus of the CTIO 4 m telescope. By comparing CCD images
