A linear filter to reconstruct the ISW effect from CMB and LSS observations
R. B. Barreiro, P. Vielva, C. Hernandez-Monteagudo +1
The extraction of a signal from some observational data sets that contain different contaminant emissions, often at a greater level than the signal itself, is a common problem in A…
Implementation of a Fourier Matched Filter in CMB Analyses. Application to ISW Studies
Carlos Hernandez-Monteagudo
Aims: Implement a matched filter (MF) cross-correlation algorithm in multipole space and compare it to the standard Angular Cross Power Spectrum (ACPS) method. Apply both methods o…
Missing baryons, bulk flows and the E-mode polarization of the Cosmic Microwave Background
Carlos Hernandez-Monteagudo, Rashid A. Sunyaev
If the peculiar motion of galaxy groups and clusters indeed resembles that of the surrounding baryons, then the kinetic Sunyaev-Zel'dovich (kSZ) pattern of those massive halos shou…
Carbon monoxide line emission as a CMB foreground: tomography of the star-forming universe with different spectral resolutions
Mattia Righi, Carlos Hernandez-Monteagudo, Rashid Sunyaev
The rotational lines of carbon monoxide and the fine structure lines of CII and of the most abundant metals, emitted during the epoch of enhanced star formation in the universe, ar…
Oxygen pumping II: Probing the Inhomogeneous Metal Enrichment at the Epoch of Reionization with High Frequency CMB Observations
Carlos Hernandez-Monteagudo, Zoltan Haiman, Licia Verde +1
At the epoch of reionization, when the high-redshift inter-galactic medium (IGM) is being enriched with metals, the 63.2 micron fine structure line of OI is pumped by the ~ 1300 AA…
The clustering of merging star-forming haloes: dust emission as high frequency arcminute CMB foreground
Mattia Righi, Carlos Hernandez-Monteagudo, Rashid Sunyaev
Future observations of CMB anisotropies will be able to probe high multipole regions of the angular power spectrum, corresponding to a resolution of a few arcminutes. Dust emission…
The Kinetic Sunyaev-Zel'dovich Effect Due to the Electrons of Our Galaxy
Amir Hajian, Carlos Hernandez-Monteagudo, Raul Jimenez +2
We compute the effect of local electrons on the CMB temperature anisotropies. The number density and distribution of free electrons in our Galaxy has been accurately measured from…
Oxygen Pumping: Mapping the Reionization Epoch with the CMB
Carlos Hernandez-Monteagudo, Zoltan Haiman, Raul Jimenez +1
We consider the pumping of the m fine structure line of neutral OI in the high--redshift intergalactic medium (IGM), in analogy with the Wouthuysen--Field effect for the 21…
The thermal Sunyaev-Zel'dovich Signature of Baryons in the Local Universe
Carlos Hernandez-Monteagudo, Hy Trac, Raul Jimenez +1
Using cosmological hydrodynamical simulations, we investigate the prospects of the thermal Sunyaev-Zel'dovich (tSZ) effect to detect the missing baryons in the local universe. We f…
Tomography of the Reionization Epoch with Multifrequency CMB Observations
Carlos Hernandez-Monteagudo, Licia Verde, Raul Jimenez
We study the constraints that future multifrequency Cosmic Microwave Background (CMB) experiments will be able to set on the metal enrichment history of the Inter Galactic Medium a…
Galaxy cluster merger kinematics by Rees-Sciama effect
Matteo Maturi, Torsten Ensslin, Carlos Hernandez-Monteagudo +1
We discuss how to use the Rees-Sciama (RS) effect associated with merging clusters of galaxies to measure their kinematic properties. In a previous work (Rubino-Martin et al. 2004)…
Correlation properties of the kinematic Sunyaev-Zel'dovich effect and implications for Dark Energy
C. Hernandez-Monteagudo, L. Verde, Raul Jimenez +1
In the context of a cosmological study of the bulk flows in the Universe, we present a detailed study of the statistical properties of the kinematic Sunyaev-Zel'dovich (kSZ) effect…
