The Intergalactic medium transmission towards z>4 galaxies with VANDELS and the impact of dust attenuation
R. Thomas, L. Pentericci, O. Le Fèvre +22
Aims. Our aim is to estimate the intergalactic medium transmission towards UV-selected star-forming galaxies at redshift 4 and above and study the effect of the dust attenuation on…
Inferences on the Timeline of Reionization at z~8 From the KMOS Lens-Amplified Spectroscopic Survey
Charlotte A. Mason, Adriano Fontana, Tommaso Treu +12
Detections and non-detections of Lyman alpha (Ly) emission from galaxies ( Gyr after the Big Bang) can be used to measure the timeline of cosmic reionization. Of key i…
To Stack or Not to Stack: Spectral Energy Distribution Properties of Lya-Emitting Galaxies at z=2.1
Carlos J. Vargas, Hannah Bish, Viviana Acquaviva +13
We use the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) GOODS-S multi-wavelength catalog to identify counterparts for 20 Lya Emitting (LAE) galaxies at…
The Lyman alpha Reference Sample: II. HST imaging results, integrated properties and trends
Matthew Hayes, Göran Östlin, Florent Duval +16
We report upon new results regarding the Lya output of galaxies, derived from the Lyman alpha Reference Sample (LARS), focusing on Hubble Space Telescope imaging. For 14 galaxies w…
The Lyman alpha Reference Sample: Extended Lyman alpha Halos Produced at Low Dust Content
Matthew Hayes, Göran Östlin, Daniel Schaerer +14
We report on new imaging observations of the Lyman alpha emission line (Lya), performed with the Hubble Space Telescope, that comprise the backbone of the Lyman alpha Reference Sam…
High resolution study of the cluster complexes in a lensed spiral at redshift ~1.5; constraints on the bulge formation and disk evolution
Angela Adamo, Goeran Ostlin, Nate Bastian +3
We analyse the clump population of the spiral galaxy Sp 1149 at redshift 1.5. Located behind the galaxy cluster MACS J1149.5+2223, Sp 1149 has been significantly magnified allowing…
Magellan/MMIRS near-infrared multi-object spectroscopy of nebular emission from star forming galaxies at 2<z<3
Lucia Guaita, Harold Francke, Eric Gawiser +4
To investigate the ingredients, which allow star-forming galaxies to present Lyalpha line in emission, we studied the kinematics and gas phase metallicity (Z) of the interstellar m…
Searching for Neutral Hydrogen Halos around z ~ 2.1 and z ~ 3.1 Ly-alpha Emitting Galaxies
John Feldmeier, Alex Hagen, Robin Ciardullo +9
We search for evidence of diffuse Ly-alpha emission from extended neutral hydrogen surrounding Ly-alpha emitting galaxies (LAEs) using deep narrow-band images of the Extended Chand…
Detecting gravitationally lensed population III galaxies with the Hubble Space Telescope and the James Webb Space Telescope
E. Zackrisson, A. Zitrin, M. Trenti +6
Small galaxies consisting entirely of population III (pop III) stars may form at high redshifts, and could constitute one of the best probes of such stars. Here, we explore the pro…
Stacked Rest-Frame UV Spectra of Ly-Emitting and Continuum-Selected Galaxies at 2<z<3.5
Michael Berry, Eric Gawiser, Lucia Guaita +6
We present properties of individual and composite rest-UV spectra of continuum- and narrowband-selected star-forming galaxies (SFGs) at a redshift of 2<z<3.5 discovered by the MUSY…
The Curious Case of Lyman Alpha Emitters: Growing Younger from z ~ 3 to z ~ 2?
Viviana Acquaviva, Carlos Vargas, Eric Gawiser +1
Lyman Alpha Emitting (LAE) galaxies are thought to be progenitors of present-day L* galaxies. Clustering analyses have suggested that LAEs at z ~ 3 might evolve into LAEs at z ~ 2,…

Viviana Acquaviva, Eric Gawiser, Lucia Guaita
We present GalMC (Acquaviva et al 2011), our publicly available Markov Chain Monte Carlo algorithm for SED fitting, show the results obtained for a stacked sample of Lyman Alpha Em…
The Evolution of Ly-alpha Emitting Galaxies Between z = 2.1 and z = 3.1
Robin Ciardullo, Caryl Gronwall, Christopher Wolf +11
We describe the results of a new, wide-field survey for z=3.1 Ly-alpha emission-line galaxies (LAEs) in the Extended Chandra Deep Field South (ECDF-S). By using a nearly top-hat 50…

Zhen-Ya Zheng, Sangeeta Malhotra, Jun-Xian Wang +7
We have coadded X-ray flux of all known Lyman Alpha Emitters (LAEs) in the 4 Msec Chandra Deep Field South (CDF-S) region, to place sensitive upper limits on the average unobscured…
