Extragalactic CO emission lines in the CMB experiments: A forgotten signal and a foreground
Lagache, Guilaine; Pullen, Anthony R.; Maniyar, Abhishek S. +3 more
High resolution cosmic microwave background (CMB) experiments have allowed us to precisely measure the CMB temperature power spectrum down to very small scales (multipole ℓ∼3000 ). Such measurements at multiple frequencies enable separating the power spectrum of the primary CMB anisotropies with the power spectrum of other signals like CMB lensing…
Investigating starburst-driven neutrino emission from galaxies in the Great Observatories All-Sky LIRG Survey
Privon, G. C.; van Eijndhoven, N.; Merckx, Y. +3 more
We present a phenomenological framework for starburst-driven neutrino production via proton-proton collisions and apply it to (ultra)luminous infrared galaxies (U/LIRGs) in the Great Observatories All-Sky LIRG Survey (GOALS). The framework relates the infrared luminosity of a GOALS galaxy, derived from consistently available Herschel Space Observa…
Atacama Cosmology Telescope: Combined kinematic and thermal Sunyaev-Zel'dovich measurements from BOSS CMASS and LOWZ halos
Hilton, Matt; Sifón, Cristóbal; Battaglia, Nicholas +56 more
The scattering of cosmic microwave background (CMB) photons off the free-electron gas in galaxies and clusters leaves detectable imprints on high resolution CMB maps: the thermal and kinematic Sunyaev-Zel'dovich effects (tSZ and kSZ respectively). We use combined microwave maps from the Atacama Cosmology Telescope DR5 and Planck in combination wit…
Atacama Cosmology Telescope: Modeling the gas thermodynamics in BOSS CMASS galaxies from kinematic and thermal Sunyaev-Zel'dovich measurements
Hilton, Matt; Sifón, Cristóbal; Battaglia, Nicholas +52 more
The thermal and kinematic Sunyaev-Zel'dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups, and clusters, since they are proportional, respectively, to the integrated electron pressure and momentum along the line of sight. We present constraints on the gas ther…
The Atacama Cosmology Telescope: Probing the baryon content of SDSS DR15 galaxies with the thermal and kinematic Sunyaev-Zel'dovich effects
Bond, J. R.; Calabrese, E.; Huffenberger, K. M. +51 more
We present measurements of the average thermal Sunyaev Zel'dovich (tSZ) effect from optically selected galaxy groups and clusters at high signal-to-noise (up to 12 σ ) and estimate their baryon content within a 2.1' radius aperture. Sources from the Sloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey DR15 catalog overlap wi…
Constraints on large-scale dark acoustic oscillations from cosmology
Cyr-Racine, Francis-Yan; de Putter, Roland; Raccanelli, Alvise +1 more
If all or a fraction of the dark matter (DM) were coupled to a bath of dark radiation (DR) in the early Universe, we expect the combined DM-DR system to give rise to acoustic oscillations of the dark matter until it decouples from the DR. Much like the standard baryon acoustic oscillations, these dark acoustic oscillations (DAO) imprint a characte…
Amplitudes of thermal and kinetic Sunyaev-Zel'dovich signals from small-scale CMB anisotropies
Melchiorri, Alessandro; Cooray, Asantha; Pagano, Luca +4 more
While the arcminute-scale cosmic microwave background (CMB) anisotropies are due to secondary effects, point sources dominate the total anisotropy power spectrum. At high frequencies the point sources are primarily in the form of dusty, star-forming galaxies. Both Herschel and Planck have recently measured the anisotropy power spectrum of cosmic i…
