TL;DR: In this paper, the authors extended the Fisher matrix analysis to a point analysis of the wide field survey data, and showed that removing 50% of the observed galaxies in the photometric clustering part of the analysis decreases the dark energy Figure of Merit (FOM).

TL;DR: In this paper, the authors present a new experiment dedicated to the study of the Cosmic Microwave Background (CMB) polarization, called QUBIC (Q and U Bolometric Interferometer for Cosmology).

TL;DR: In this article , the authors present a new calibration of the analytic HMF, at the level of accuracy and precision required for the uncertainty in this quantity to be subdominant with respect to other sources of uncertainty in recovering cosmological parameters from Euclid cluster counts.

TL;DR: In this paper, the authors used the Hot Big Bang theory with the inflation hypothesis to detect very low contrast sub-horizon scale structures in the Cosmic Microwave Background (CMB).

Abstract: In the 1998-99 flight, BOOMERanG has produced maps of ˜ 4 % of the sky at high Galactic latitudes, at frequencies of 90, 150, 240 and 410 GHz, with resolution ≳ 10'. The faint structure of the Cosmic Microwave Background at horizon and sub-horizon scales is evident in these maps. These maps compare well to the maps recently obtained at lower frequencies by the WMAP experiment. Here we compare the amplitude and morphology of the structures observed in the two sets of maps. We also outline the polarization sensitive version of BOOMERanG, which was flown early this year to measure the linear polarization of the microwave sky at 150, 240 and 350 GHz.
