Sub-percent constraints on cosmological temperature evolution
A. Avgoustidis, R. T. Génova-Santos, G. Luzzi +1
The redshift dependence of the cosmic microwave background temperature is one of the key cosmological observables. In the standard cosmological model one has , where…
SN 2014J at M82: I. A middle-class type Ia supernova by all spectroscopic metrics
L. Galbany, M. E. Moreno-Raya, P. Ruiz-Lapuente +20
We present the intensive spectroscopic follow up of the type Ia supernova (SN Ia) 2014J in the starburst galaxy M82. Twenty-seven optical spectra have been acquired from January 22…
The QUIJOTE experiment: project overview and first results
R. Génova-Santos, J. A. Rubiño-Martín, R. Rebolo +50
QUIJOTE (Q-U-I JOint TEnerife) is a new polarimeter aimed to characterize the polarization of the Cosmic Microwave Background and other Galactic and extragalactic signals at medium…
Planck Intermediate Results. XXXVI. Optical identification and redshifts of Planck SZ sources with telescopes in the Canary Islands Observatories
Planck Collaboration, P. A. R. Ade, N. Aghanim +187
We present the results of approximately three years of observations of Planck Sunyaev-Zeldovich (SZ) sources with telescopes at the Canary Islands observatories as part of the gene…
Planck intermediate results. XXXVII. Evidence of unbound gas from the kinetic Sunyaev-Zeldovich effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +189
By looking at the kinetic Sunyaev-Zeldovich effect (kSZ) in Planck nominal mission data, we present a significant detection of baryons participating in large-scale bulk flows aroun…
Planck 2015 results. XXII. A map of the thermal Sunyaev-Zeldovich effect
Planck Collaboration, N. Aghanim, M. Arnaud +199
We have constructed all-sky y-maps of the thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored component separation algorithms to the 30 to 857 GHz frequency ch…
Planck 2015 results. XXI. The integrated Sachs-Wolfe effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +229
This paper presents a study of the ISW effect from the Planck 2015 temperature and polarization data release. The CMB is cross-correlated with different LSS tracers: the NVSS, SDSS…
Measurements of the Intensity and Polarization of the Anomalous Microwave Emission in the Perseus molecular complex with QUIJOTE
R. Génova-Santos, J. A. Rubiño-Martín, R. Rebolo +27
Anomalous microwave emission (AME) has been observed in numerous sky regions, in the frequency range ~10-60 GHz. One of the most scrutinized regions is G159.6-18.5, located within…
