Revisiting the WMAP - NVSS angular cross correlation. A skeptic view (2009)
In the context of the study of the ISW, we revisit the angular cross correlation of WMAP CMB data with the NVSS radio survey. We compute 2-point cross functions between the two surveys in real and in...
Simulations of the Microwave Sky (2009)
Sehgal, Neelima, Bode, Paul, Das, Sudeep, Hernandez-Monteagudo, Carlos, Huffenberger, Kevin, Lin, Yen-Ting, ...
We create realistic, full-sky, half-arcminute resolution simulations of the microwave sky matched to the most recent astrophysical observations. The primary purpose of these simulations is to test...
Non-Gaussian Distribution and Clustering of Hot and Cold Pixels in the WMAP Five-Year Sky (2009)
Rossi, Graziano, Sheth, Ravi K., Park, Changbom, Hernandez-Monteagudo, Carlos
We present measurements of the clustering of hot and cold patches in the microwave background sky as measured from the Wilkinson Microwave Anisotropy Probe (WMAP) five-year data. These measurements...
Galaxy Clusters as mirrors of the distant Universe. Implications for the kSZ and ISW effects (2009)
Hernandez-Monteagudo, Carlos, Sunyaev, Rashid A.
It is well known that Thomson scattering of CMB photons in galaxy clusters introduces new anisotropies in the CMB radiation field, but however little attention is payed to the fraction of CMB photons...
Smith, Robert E., Hernandez-Monteagudo, Carlos, Seljak, Uros
We investigate the impact of nonlinear evolution of the gravitational potentials in the LCDM model on the Integrated Sachs-Wolfe (ISW) contribution to the CMB temperature power spectrum, and on the...
On the peculiar momentum of baryons after Reionization (2009)
Hernandez-Monteagudo, Carlos, Ho, Shirley
The peculiar motion of ionized baryons is known to introduce temperature anisotropies in the CMB by means of the kinetic Sunyaev-Zel'dovich effect (kSZ). In this work, we present an all sky...
Observing the Evolution of the Universe (2009)
Aguirre, James, Amblard, Alexandre, Ashoorioon, Amjad, Baccigalupi, Carlo, Balbi, Amedeo, Bartlett, James, ...
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed...

Menanteau, Felipe, Hughes, John P., Jimenez, Raul, Hernandez-Monteagudo, Carlos, Verde, Licia, Kosowsky, Arthur, ...
We present first results from the Southern Cosmology Survey, a new multiwavelength survey of the southern sky coordinated with the Atacama Cosmology Telescope (ACT), a recently commissioned...
Missing baryons, bulk flows and the E-mode polarization of the Cosmic Microwave Background (2008)
Hernandez-Monteagudo, Carlos, Sunyaev, Rashid A.
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 should be closely...
Implementation of a Fourier Matched Filter in CMB Analyses. Application to ISW Studies (2008)
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 on a Integrated...
Righi, Mattia, Hernandez-Monteagudo, Carlos, Sunyaev, Rashid
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, are redshifted in the...
Hernandez-Monteagudo, Carlos, Haiman, Zoltan, Verde, Licia, Jimenez, Raul
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 soft UV background...
Righi, Mattia, Hernandez-Monteagudo, Carlos, Sunyaev, Rashid
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 from merging...
The Kinetic Sunyaev-Zel'dovich Effect Due to the Electrons of Our Galaxy (2007)
Hajian, Amir, Hernandez-Monteagudo, Carlos, Jimenez, Raul, Spergel, David, Verde, Licia
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 pulsar dispersion...
Oxygen Pumping: Mapping the Reionization Epoch with the CMB (2006)
Hernandez-Monteagudo, Carlos, Haiman, Zoltan, Jimenez, Raul, Verde, Licia
We consider the pumping of the $63.2 \mu$m fine structure line of neutral OI in the high--redshift intergalactic medium (IGM), in analogy with the Wouthuysen--Field effect for the 21cm line of cosmic...
The thermal Sunyaev-Zel'dovich Signature of Baryons in the Local Universe (2006)
Hernandez-Monteagudo, Carlos, Trac, Hy, Jimenez, Raul, Verde, Licia
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 find that at least...
