A hyper luminous starburst at z=4.72 magnified by a lensing galaxy pair at z=1.48
L. Ciesla, M. Béthermin, E. Daddi +23
[Abridged] We discovered in the Herschel Reference Survey an extremely bright IR source with ~120mJy (Red Virgo 4 - RV4). Based on IRAM/EMIR and IRAM/NOEMA detections of t…
Onset of Cosmic Reionization: Evidence of An Ionized Bubble Merely 680 Myrs after the Big Bang
V. Tilvi, S. Malhotra, J. E. Rhoads +14
While most of the inter-galactic medium (IGM) today is permeated by ionized hydrogen, it was largely filled with neutral hydrogen for the first 700 million years after the Big Bang…
MusE GAs FLOw and Wind (MEGAFLOW) XII. Rationale and design of a MgII survey of the cool circum-galactic medium with MUSE and UVES: The MEGAFLOW Survey
N. F. Bouché, M. Wendt, J. Zabl +11
We present the design, rationale, properties and catalogs of the MusE Gas FLOw and Wind survey (MEGAFLOW), a survey of the cool gaseous halos of galaxies using low-ionizat…
UltraVISTA: a new ultra-deep near-infrared survey in COSMOS
H. J. McCracken, B. Milvang-Jensen, J. Dunlop +18
In this paper we describe the first data release of the UltraVISTA near-infrared imaging survey of the COSMOS field. We summarise the key goals and design of the survey and provide…
Faint end of the luminosity function of Lyman-alpha emitters behind lensing clusters observed with MUSE
G. de La Vieuville, D. Bina, R. Pello +21
We present the results obtained with VLT/MUSE on the faint-end of the Lyman-alpha luminosity function (LF) based on deep observations of four lensing clusters. The precise aim of t…
Thirty-fold: Extreme gravitational lensing of a quiescent galaxy at
H. Ebeling, M. Stockmann, J. Richard +4
We report the discovery of eMACSJ1341-QG-1, a quiescent galaxy at located behind the massive galaxy cluster eMACSJ1341.92442 (). The system was identified as…
MusE GAs FLOw and Wind (MEGAFLOW) IX. The impact of gas flows on the relations between the mass, star formation rate and metallicity of galaxies
I. Langan, J. Zabl, N. F. Bouche +13
We study the link between gas flow events and key galaxy scaling relations: the relations between star formation rate (SFR) and stellar mass (the main sequence, MS), gas metallicit…
Determining the fraction of reddened quasars in COSMOS with multiple selection techniques from X-ray to radio wavelengths
K. E. Heintz, J. P. U. Fynbo, P. Møller +8
The sub-population of quasars reddened by intrinsic or intervening clouds of dust are known to be underrepresented in optical quasar surveys. By defining a complete parent sample o…
A Method to improve line flux and redshift measurements with narrowband filters
J. Zabl, W. Freudling, P. Møller +5
High redshift star-forming galaxies are discovered routinely through a flux excess in narrowband filters (NB) caused by an emission line. In most cases, the width of such filters i…
Recovering the systemic redshift of galaxies from their Lyman-alpha line profile
A. Verhamme, T. Garel, E. Ventou +23
The Lyman alpha (lya) line of Hydrogen is a prominent feature in the spectra of star-forming galaxies, usually redshifted by a few hundreds of km/s compared to the systemic redshif…
On-sky characterisation of the VISTA NB118 narrow-band filters at 1.19 micron
B. Milvang-Jensen, W. Freudling, J. Zabl +9
Observations of the high redshift Universe through narrow-band filters have proven very successful in the last decade. The 4-meter VISTA telescope, equipped with the wide-field cam…
The COSMOS2015 Catalog: Exploring the 1<z<6 Universe with half a million galaxies
C. Laigle, H. J. McCracken, O. Ilbert +34
We present the COSMOS2015 catalog which contains precise photometric redshifts and stellar masses for more than half a million objects over the 2deg COSMOS field. Including n…
Deep rest-frame far-UV spectroscopy of the giant Lyman-alpha emitter 'Himiko'
J. Zabl, H. U. Nørgaard-Nielsen, J. P. U. Fynbo +3
We present deep 10h VLT/XSHOOTER spectroscopy for an extraordinarily luminous and extended Lya emitter at z=6.595 referred to as Himiko and first discussed by Ouchi et al. (2009),…
Emission line selected galaxies at in GOODS South: Stellar masses, SFRs, and large scale structure
I. Kochiashvili, P. Møller, B. Milvang-Jensen +7
We have obtained deep NIR narrow and broad (J and Y) band imaging data of the GOODS-South field. The narrow band filter is centered at 1060 nm corresponding to redshifts $z = 0.62,…
The properties of GRB 120923A at a spectroscopic redshift of z=7.8
N. R. Tanvir, T. Laskar, A. J. Levan +37
Gamma-ray bursts (GRBs) are powerful probes of early stars and galaxies, during and potentially even before the era of reionization. Although the number of GRBs identified at z>6 r…
