Lyα Emission-Line Galaxies at z = 3.1 in the Extended Chandra Deep Field-South
- C. Gronwall, R. Ciardullo, +13 authors E. Treister
- Physics
- 28 May 2007
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… Expand
Lyα-Emitting Galaxies at z = 3.1: L* Progenitors Experiencing Rapid Star Formation*
- E. Gawiser, H. Francke, +19 authors for the Musyc Collaboration
- Physics
- 14 October 2007
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… Expand
Planetary Nebulae as Standard Candles. XI. Application to Spiral Galaxies
- J. Feldmeier, R. Ciardullo, G. Jacoby
- Physics
- 5 November 1996
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]… Expand
Planetary nebulae as standard candles. II. The calibration in M31 and its companions
- R. Ciardullo, G. Jacoby, H. Ford, J. Neill
- Physics
- 1 April 1989
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… Expand
A HUBBLE SPACE TELESCOPE Survey for Resolved Companions of Planetary Nebula Nuclei
- R. Ciardullo, H. Bond, +7 authors Towson University
- Physics
- 3 April 1999
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… Expand
The physical nature of Lyα-emitting galaxies at z = 3.1
- E. Gawiser, P. V. Dokkum, +21 authors for the Musyc Collaboration
- Physics
- 9 March 2006
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… Expand
Lyα-EMITTING GALAXIES AT z = 2.1 IN ECDF-S: BUILDING BLOCKS OF TYPICAL PRESENT-DAY GALAXIES?*
- L. Guaita, E. Gawiser, +8 authors S. Virani
- Physics
- 12 October 2009
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… Expand
THE HETDEX PILOT SURVEY. II. THE EVOLUTION OF THE Lyα ESCAPE FRACTION FROM THE ULTRAVIOLET SLOPE AND LUMINOSITY FUNCTION OF 1.9 < z < 3.8 LAEs
- G. Blanc, J. Adams, +51 authors S. Barbara
- Physics
- 1 November 2010
We study the escape of Lyα photons from Lyα emitting galaxies (LAEs) and the overall galaxy population using a sample of 99 LAEs at 1.9 (3-6) × 1042 erg s–1 (0.25-0.5 L*), have a mean E(B – V) = 0.13… Expand
The planetary nebula system and dynamics of NGC 5128. I - Planetary nebulae as standard candles
- X. Hui, H. Ford, R. Ciardullo, G. Jacoby
- Physics
- 10 September 1993
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… Expand
Planetary Nebulae in Face-On Spiral Galaxies. I. Planetary Nebula Photometry and Distances

- Physics
- 7 May 2008
As the first step to determine disk mass-to-light ratios for normal spiral galaxies, we present the results of an imaging survey for planetary nebulae (PNe) in six nearby, face-on systems: IC 342,… Expand
