Seven broad absorption line quasars with excess broad band absorption near 2250 Å
Shaohua Zhang, Jian Ge, Peng Jiang +6
We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results fr…
Recent stellar mass assembly of low-mass star-forming galaxies at redshifts 0.3 < z < 0.9
Lucía Rodríguez-Muñoz, Jesús Gallego, Camilla Pacifici +5
The epoch when low-mass star forming galaxies (LMSFGs) form the bulk of their stellar mass is uncertain. While some models predict an early formation, others favor a delayed scenar…
Galactic nebular lines in the fiber spectra of background QSOs: Reaching a hundred QSO-galaxy pairs with spectroscopic and photometric measurements
Lorrie Straka, Pasquier Noterdaeme, Raghunathan Srianand +6
We present photometric and spectroscopic measurements of 53 QSO-galaxy pairs from the Sloan Digital Sky Survey, where nebular emission lines from a 0<z<0.84 foreground galaxy are d…
A Critical Look at the Mass-Metallicity-SFR Relation in the Local Universe. I. An Improved Analysis Framework and Confounding Systematics
Samir Salim, Janice C. Lee, Chun Ly +5
It has been proposed that the mass-metallicity relation of galaxies exhibits a secondary dependence on star formation rate (SFR), and that the resulting M-Z-SFR relation may be red…
The evolution of the cluster optical galaxy luminosity function between z=0.4 and 0.9 in the DAFT/FADA survey
Nicolas Martinet, Florence Durret, Loic Guennou +8
We compute optical galaxy luminosity functions (GLFs) in the B, V, R, and I rest-frame bands for one of the largest medium-to-high-redshift (0.4 < z < 0.9) cluster samples to date…
Structure of the nucleus of 1928+738
J. Roland, S. Britzen, E. Kun +3
Modeling of the trajectories of VLBI components ejected by the nucleus of 1928+738 shows the VLBI jet contains three families of trajectories, i.e. VLBI components are ejected from…
Evolution of the Milky Way with radial motions of stars and gas II. The evolution of abundance profiles from H to Ni
M. Kubryk, N. Prantzos, E. Athanassoula
We study the role of radial motions of stars and gas on the evolution of abundance profiles in the Milky Way disk. We investigate, in a parametrized way, the impact of radial flows…
Scaling Relations Between Warm Galactic Outflows and Their Host Galaxies
John Chisholm, Christina A. Tremonti, Claus Leitherer +3
We report on a sample of 51 nearby, star-forming galaxies observed with the Cosmic Origin Spectrograph on the Hubble Space Telescope. We calculate Si II kinematics and densities ar…
Disk fragmentation and the formation of population III stars
M. A. Latif, D. R. G. Schleicher
Our understanding of population III star formation is still in its infancy. They are formed in dark matter minihalos of at . Recent high resoluti…
The evolution of the cold interstellar medium in galaxies following a starburst
K. Rowlands, V. Wild, N. Nesvadba +4
We present the evolution of dust and molecular gas properties in a sample of 11 starburst to post-starburst (PSB) galaxies selected to span an age sequence from ongoing…
Evolution of the Milky Way with radial motions of stars and gas I. The solar neighborhood and the thin and thick disk
M. Kubryk, N. Prantzos, E. Athanassoula
We study the role of radial migration of stars on the chemical evolution of the Milky Way disk. In particular, we are interested in the impact of that process on the local properti…
On the importance of using appropriate spectral models to derive physical properties of galaxies at 0.7<z<2.8
Camilla Pacifici, Elisabete da Cunha, Stéphane Charlot +14
Interpreting observations of distant galaxies in terms of constraints on physical parameters - such as stellar mass, star-formation rate (SFR) and dust optical depth - requires spe…
The evolving SFR-M_star relation and sSFR since z~5 from the VUDS spectroscopic survey
L. A. M. Tasca, O. Le Fevre, N. P. Hathi +44
We study the evolution of the star formation rate (SFR) - stellar mass (M_star) relation and specific star formation rate (sSFR) of star forming galaxies (SFGs) since a redshift z~…
Galaxy merger histories and the role of merging in driving star formation at z>1
S. Kaviraj, J. Devriendt, Y. Dubois +5
We use Horizon-AGN, a hydrodynamical cosmological simulation, to explore the role of mergers in the evolution of massive (M > 10^10 MSun) galaxies around the epoch of peak cosmic s…
Exceptional AGN-driven turbulence inhibits star formation in the 3C 326N radio-galaxy
P. Guillard, F. Boulanger, M. D. Lehnert +4
We detect bright [CII]158m line emission from the radio galaxy 3C 326N at z=0.09, which shows weak star formation (M~yr) despite having strong H l…
Reconstructing the star formation history of the Milky Way disc(s) from chemical abundances
O. Snaith, M. Haywood, P. Di Matteo +4
We develop a chemical evolution model in order to study the star formation history of the Milky Way. Our model assumes that the Milky Way is formed from a closed box-like system in…
Why the Milky Way's bulge is not only a bar formed from a cold thin disk
P. Di Matteo, A. Gomez, M. Haywood +6
By analyzing a N-body simulation of a bulge formed simply via a bar instability mechanism operating on a kinematically cold stellar disk, and by comparing the results of this analy…
The formation of supermassive black holes in rapidly rotating disks
M. A. Latif, D. R. G. Schleicher
Massive primordial halos exposed to moderate UV backgrounds are the potential birthplaces of supermassive black holes. In such a halo, an initially isothermal collapse will occur,…
Marginal likelihoods of distances and extinctions to stars: computation and compact representation
