AtLAST -- Determination of Halo Mass Density Profiles at kpc Scales through Magnification Bias
Joaquín González-Nuevo, Laura Bonavera, Juan Alberto Cano +9
Magnification bias, the lensing-induced modification of background source number counts, provides a uniquely powerful probe of the mass density profiles of galaxies and clusters do…
AtLAST -- Cosmology with submillimetre galaxies magnification bias
Laura Bonavera, Joaquin Gonzalez-Nuevo, Juan Alberto Cano +10
Magnification bias offers a uniquely powerful and independent route to cosmological information. As a gravitational-lensing observable, it probes galaxy-matter correlations without…
Close-up view of a luminous star-forming galaxy at z=2.95
S. Berta, A. J. Young, P. Cox +35
(Abridged) Exploiting the sensitivity and broad band width of NOEMA, we have studied the molecular gas and dust in the galaxy HerBS-89a, at z=2.95. High angular resolution images r…
Setting new Cosmology constraints with ALMA
Hugo Messias
I make a short revision of Cosmology questions which ALMA was built to address. Without diving into much detail, I point out the ALMA specifications and strategies which are expect…
Hot-Dust (690K) Luminosity Density and its Evolution in the last 7.5Gyr
Hugo Messias, Bahram Mobasher, José Manuel Afonso
[Abridged] We study the contribution of hot-dust to the luminosity density of galaxies and its evolution with cosmic time. Using the Spitzer-IRAC data in the COSMOS field, we estim…
The Spitzer Extragalactic Representative Volume Survey (SERVS): survey definition and goals
J. -C. Mauduit, M. Lacy, D. Farrah +81
We present the Spitzer Extragalactic Representative Volume Survey (SERVS), an 18 square degrees medium-deep survey at 3.6 and 4.5 microns with the post-cryogenic Spitzer Space Tele…
A new infrared color criterion for the selection of 0<z<7 AGN: application to deep fields and implications for JWST surveys
Hugo Messias, Jose M. Afonso, Mara Salvato +2
[Abridged] It is widely accepted that observations at mid-infrared (mid-IR) wavelengths enable the selection of galaxies with nuclear activity, which may not be revealed even in th…
A multiwavelength study of near- and mid-infrared selected galaxies at high redshift: ERGs, AGN-identification and the contribution from dust
Hugo Messias
The main focus of this thesis is the IR spectral regime, which since the 70's and 80's has revolutionised our understanding of the Universe. A multi-wavelength analysis on Extremel…
Clustering properties of BzK-selected galaxies in GOODS-N: environmental quenching and triggering of star formation at z ~ 2
Lihwai Lin, Mark Dickinson, Hung-Yu Jian +19
Using a sample of BzK-selected galaxies at z~2 identified from the CFHT/WIRCAM near-infrared survey of GOODS-North, we discuss the relation between star formation rate (SFR), speci…
How Do Star-Forming Galaxies at Z>3 Assemble Their Masses?
Kyoung-Soo Lee, Henry C. Ferguson, Tommy Wiklind +8
We investigate how star-forming galaxies typically assemble their masses at high redshift. Using the deep multi-wavelength coverage of the GOODS dataset, we measure stellar mass of…
Rest-frame UV--Optically Selected Galaxies at 2.3<z<3.5: Searching for Dusty Star-forming and Passively-Evolving Galaxies
Yicheng Guo, Mauro Giavalisco, Paolo Cassata +17
A new set of color selection criteria (VJL) analogous with the BzK method is designed to select both star-forming galaxies (SFGs) and passively-evolving galaxies (PEGs) at 2.3<z<3.…
Ultra Steep Spectrum radio sources in the Lockman Hole: SERVS identifications and redshift distribution at the faintest radio fluxes
J. Afonso, L. Bizzocchi, E. Ibar +26
Ultra Steep Spectrum (USS) radio sources have been successfully used to select powerful radio sources at high redshifts (z>~2). Typically restricted to large-sky surveys and relati…
Dissecting Photometric redshift for Active Galactic Nuclei using XMM- and Chandra-COSMOS samples
M. Salvato, O. Ilbert, G. Hasinger +61
With this paper, we release accurate photometric redshifts for 1692 counterparts to Chandra sources in the central square degree of the COSMOS field. The availability of a large tr…
EMU: Evolutionary Map of the Universe
Ray P. Norris, A. M. Hopkins, J. Afonso +54
EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~ 10 m…
A multi-wavelength approach to the properties of Extremely Red Galaxy populations: I - Contribution to the Star Formation Rate density and AGN content
Hugo Messias, Jose Afonso, Andrew Hopkins +3
We present a multi-wavelength analysis of the properties of Extremely Red Galaxy (ERG) populations, selected in the GOODS-South/Chandra Deep Field South field. By using all the pho…
