The Gaia-ESO Survey: Separating disk chemical substructures with cluster models
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +24
(Abridged) Recent spectroscopic surveys have begun to explore the Galactic disk system outside the solar neighborhood on the basis of large data samples. In this way, they provide…
The Lyman alpha Reference Sample VI: Lyman alpha escape from the edge-on disk galaxy Mrk1486
Florent Duval, Göran Östlin, Matthew Hayes +16
While numerical simulations suggest that the strength of the Lyman alpha (Lya) line of star-forming disk galaxies strongly depends on the inclination at which they are observed (i.…
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
Detecting Direct Collapse Black Holes: making the case for CR7
Bhaskar Agarwal, Jarrett L. Johnson, Erik Zackrisson +4
We propose that one of the sources in the recently detected system CR7 by Sobral et al. (2015) through spectro-photometric measurements at harbors a direct collapse black…
Ionization processes in a local analogue of distant clumpy galaxies: VLT MUSE IFU spectroscopy and FORS deep images of the TDG NGC 5291N
J. Fensch, P. -A. Duc, P. M. Weilbacher +2
We present IFU observations with MUSE@VLT and deep imaging with FORS@VLT of a dwarf galaxy recently formed within the giant collisional HI ring surrounding NGC 5291. This TDG-like…
The Gaia-ESO Survey: New constraints on the Galactic disc velocity dispersion and its chemical dependencies
G. Guiglion, A. Recio-Blanco, P. de Laverny +27
Understanding the history and the evolution of the Milky Way disc is one of the main goals of modern astrophysics. We study the velocity dispersion behaviour of Galactic disc stars…
Star Cluster Properties in Two LEGUS Galaxies Computed with Stochastic Stellar Population Synthesis Models
Mark R. Krumholz, Angela Adamo, Michele Fumagalli +14
We investigate a novel Bayesian analysis method, based on the Stochastically Lighting Up Galaxies (slug) code, to derive the masses, ages, and extinctions of star clusters from int…
Extragalactic SETI: The Tully-Fisher relation as a probe of Dysonian astroengineering in disk galaxies
E. Zackrisson, P. Calissendorff, S. Asadi +1
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxi…
The Brightest Young Star Clusters in NGC 5253
D. Calzetti, K. E. Johnson, A. Adamo +43
The nearby dwarf starburst galaxy NGC5253 hosts a number of young, massive star clusters, the two youngest of which are centrally concentrated and surrounded by thermal radio emiss…
Kinematics of Haro11 - the miniature Antennae
Göran Östlin, Thomas Marquart, Robert Cumming +5
(abridged) Luminous blue compact galaxies are among the most active galaxies in the local universe in terms of their star formation rate per unit mass. They may be seen as the loca…
The Gaia-ESO Survey: Characterisation of the [alpha/Fe] sequences in the Milky Way discs
G. Kordopatis, R. F. G. Wyse, G. Gilmore +30
We investigate, using the Gaia-ESO Survey internal Data-Release 2, the properties of the double sequence of the Milky Way discs (defined chemically as the high-alpha and low-alpha…
The Gaia-ESO Survey: Insights on the inner-disc evolution from open clusters
L. Magrini, S. Randich, P. Donati +37
Context. The inner disc, linking the thin disc with the bulge, has been somehow neglected in the past because of intrinsic difficulties in its study, due, e.g., to crowding and hig…
Kinematics and chemistry of recently discovered Reticulum 2 and Horologium 1 dwarf galaxies
Sergey E. Koposov, Andrew R. Casey, Vasily Belokurov +17
Photometry alone is not sufficient to unambiguously distinguish between ultra-faint star clusters and dwarf galaxies because of their overlap in morphological properties. Here we r…
The Gaia-ESO Survey: a quiescent Milky Way with no significant dark/stellar accreted disc
G. R. Ruchti, J. I. Read, S. Feltzing +26
According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will…
The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
The Lyman alpha reference sample: IV. Morphology at low and high redshift
L. Guaita, J. Melinder, M. Hayes +3
We measured the sizes and morphological parameters of LARS galaxies in the continuum, Lya, and Ha images. We studied morphology by using the Gini coefficient vs M20 and asymmetry v…
Local starburst galaxies and their descendants
Nils Bergvall, Thomas Marquart, Michael J. Way +4
Despite strong interest in the starburst (hereafter SB) phenomenon, the concept remains ill-defined. We use a strict definition of SB to examine the statistical properties of local…
The Science Case for Multi-Object Spectroscopy on the European ELT
Chris Evans, Mathieu Puech, Jose Afonso +68
This White Paper presents the scientific motivations for a multi-object spectrograph (MOS) on the European Extremely Large Telescope (E-ELT). The MOS case draws on all fields of co…
