The European Space Agency's Planck satellite, dedicated to studying the early Universe
and its subsequent evolution, was launched 14 May 2009 and has been scanning the …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

Planck has produced detailed all-sky observations over nine frequency bands between 30
and 857 GHz. These observations allow robust reconstruction of the primordial cosmic …

Measurements of the anisotropies in the cosmic microwave background (CMB) radiation
have provided a wealth of information about the cosmological model that describes the …

We present the Black Hole Explorer (BHEX), a mission that will produce the sharpest images
in the history of astronomy by extending submillimeter Very-Long-Baseline Interferometry …

In the past few decades, the field of cosmology has undergone a period of dramatically rapid
progress in which a standard model of cosmology has emerged, ΛCDM. The precision with …

The European Space Agency's Planck satellite, launched on 14 May 2009, is the third-
generation space experiment in the field of cosmic microwave background (CMB) research …

The European Space Agency's Planck satellite was launched on 14 May 2009, and has
been surveying the sky stably and continuously since 13 August 2009. Its performance is …

Context. The High Frequency Instrument (HFI) is one of the two focal instruments of the
Planck mission. It will observe the whole sky in six bands in the 100 GHz–1 THz range …

In this paper we present the Low Frequency Instrument (LFI), designed and developed as
part of the Planck space mission, the ESA programme dedicated to precision imaging of the …
