HerMES: SPIRE/Sub-millimetre Emission from Radio Selected AGN
N. Seymour, M. Symeonidis, M. Page +1
We examine the rest-frame far-infrared emission from powerful radio sources with 1.4GHz luminosity densities of 25<=log(L_1.4/WHz^-1)<=26.5 in the extragalactic Spitzer First Look…
The ISW-tSZ cross correlation: ISW extraction out of pure CMB data
N. Taburet, C. Hernandez-Monteagudo, N. Aghanim +2
If Dark Energy introduces an acceleration in the universal expansion then large scale gravitational potential wells should be shrinking, causing a blueshift in the CMB photons that…
Observing the Big Bounce with Tensor Modes in the Cosmic Microwave Background: Phenomenology and Fundamental LQC Parameters
J. Grain, A. Barrau, T. Cailleteau +1
Cosmological models where the standard big bang is replaced by a bounce have been studied for decades. The situation has, however, dramatically changed in the past years for two re…
Influence of the Environment on PAH Emission in Star-Forming Regions
V. Lebouteiller, J. Bernard-Salas, D. G. Whelan +5
We investigate the emission properties of polycyclic aromatic hydrocarbons (PAHs) in various metallicity environments with the Infrared Spectrograph on board Spitzer. Local giant H…
Bispectra from two-field inflation using the long-wavelength formalism
Eleftheria Tzavara, Bartjan van Tent
We use the long-wavelength formalism to compute the bispectral non-Gaussianity produced in two-field inflation. We find an exact result that is used as the basis of numerical studi…
The black holes of radio galaxies during the "Quasar Era": Masses, accretion rates, and evolutionary stage
Nicole P. H. Nesvadba, Carlos De Breuck, Matt D. Lehnert +3
We present an analysis of the AGN broad-line regions of 6 powerful radio galaxies at z>~2 (HzRGs) with rest-frame optical imaging spectroscopy obtained at the VLT. All galaxies hav…
The Detection of a Population of Submillimeter-Bright, Strongly-Lensed Galaxies
Mattia Negrello, R. Hopwood, G. De Zotti +86
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual p…
Herschel-ATLAS: Statistical Properties of Galactic Cirrus in the GAMA-9 Hour Science Demonstration Phase Field
Andrea Bracco, Asantha Cooray, M. Veneziani +35
We study the Spectral Energy Distribution (SED) and the power spectrum of Galactic cirrus emission observed in the 14 deg^2 Science Demonstration Phase field of the Herschel-ATLAS…
Spitzer Imaging of Herschel-ATLAS Gravitationally Lensed Submillimeter Sources
R. Hopwood, J. Wardlow, A. Cooray +49
We present physical properties of two submillimeter selected gravitationally lensed sources, identified in the Herschel Astrophysical Terahertz Large Area Survey. These submillimet…
Spectroscopic confirmation of a galaxy at redshift z=8.6
M. D. Lehnert, N. P. H. Nesvadba, J. -G. Cuby +6
Galaxies had their most significant impact on the Universe when they assembled their first generations of stars. Energetic photons emitted by young, massive stars in primeval galax…
The Spitzer High Redshift Radio Galaxy Survey
Carlos De Breuck, Nick Seymour, Daniel Stern +8
We present results from a comprehensive imaging survey of 70 radio galaxies at redshifts 1<z<5.2 using all three cameras onboard the Spitzer Space Telescope. The resulting spectral…
The far-infrared view of M87 as seen by the Herschel Space Observatory
M. Baes, M. Clemens, E. M. Xilouris +29
The origin of the far-infrared emission from the nearby radio galaxy M87 remains a matter of debate. Some studies find evidence of a far-infrared excess due to thermal dust emissio…
Dark energy constraints from a space-based supernova survey
P. Astier, J. Guy, R. Pain +1
We present a forecast of dark energy constraints that could be obtained from a large sample of distances to Type Ia supernovae detected and measured from space. We simulate the sup…
Modeling the evolution of infrared galaxies: A Parametric backwards evolution model
Matthieu Béthermin, Hervé Dole, Guilaine Lagache +2
We aim at modeling the infrared galaxy evolution in an as simple as possible way and reproduce statistical properties among which the number counts between 15 microns and 1.1 mm, t…
HerMES: Deep Galaxy Number Counts from a P(D) Fluctuation Analysis of SPIRE Science Demonstration Phase Observations
J. Glenn, A. Conley, M. Bethermin +71
Dusty, star forming galaxies contribute to a bright, currently unresolved cosmic far-infrared background. Deep Herschel-SPIRE images designed to detect and characterize the galaxie…
Jet-Powered Molecular Hydrogen Emission from Radio Galaxies
Patrick Ogle, Francois Boulanger, Pierre Guillard +5
H2 pure-rotational emission lines are detected from warm (100-1500 K) molecular gas in 17/55 (31% of) radio galaxies at redshift z<0.22 observed with the Spitzer IR Spectrograph. T…
HerMES: Herschel-SPIRE observations of Lyman Break Galaxies
D. Rigopoulou, G. E. Magdis, R. J. Ivison +47
We present first results of a study of the submillimetre (rest frame far-infrared) properties of z~3 Lyman Break Galaxies (LBGs) and their lower-redshift counterparts BX/BM galaxie…
The Herschel Multi-Tiered Extragalactic Survey: Source Extraction and Cross-Identifications in Confusion-Dominated SPIRE Images
