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…
The - relation and the internal shock model
R. Mochkovitch, L. Nava
The validity of the - correlation in gamma-ray bursts and the possibility of explaining the prompt emission with internal shocks are highly debated questi…
The stellar mass - halo mass relation from galaxy clustering in VUDS: a high star formation efficiency at z~3
A. Durkalec, O. Le Fèvre, S. de la Torre +45
The relation between the galaxy stellar mass M_star and the dark matter halo mass M_h gives important information on the efficiency in forming stars and assembling stellar mass in…
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…
An optimal estimator for resonance bispectra in the CMB
Moritz Münchmeyer, P. Daniel Meerburg, Benjamin D. Wandelt
We propose an (optimal) estimator for a CMB bispectrum containing logarithmically spaced oscillations. There is tremendous theoretical interest in such bispectra, and they are pred…
Cosmological Perturbation Theory for streams of relativistic particles
Hélène Dupuy, Francis Bernardeau
Motion equations describing streams of relativistic particles and their properties are explored in detail in the framework of Cosmological Perturbation Theory. Those equations, der…
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…
A Novel, Fully Automated Pipeline for Period Estimation in the EROS 2 Data Set
Pavlos Protopapas, Pablo Huijse, Pablo A. Estevez +2
We present a new method to discriminate periodic from non-periodic irregularly sampled lightcurves. We introduce a periodic kernel and maximize a similarity measure derived from in…
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…
Bayesian inference of CMB gravitational lensing
Ethan Anderes, Benjamin Wandelt, Guilhem Lavaux
The Planck satellite, along with several ground based telescopes, have mapped the cosmic microwave background (CMB) at sufficient resolution and signal-to-noise so as to allow a de…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
Dark Matter vs. Neutrinos: The effect of astrophysical uncertainties and timing information on the neutrino floor
Jonathan H. Davis
Future multi-tonne Direct Detection experiments will be sensitive to solar neutrino induced nuclear recoils which form an irreducible background to light Dark Matter searches. Inde…
