Atomic hydrogen (Hi) is a critical step** stone in the gas evolution cycle of the interstellar
medium (ISM) of the Milky Way. Hi traces both the cold, premolecular state before star …

Context. Measurement of the Galactic neutral atomic hydrogen (H i) column density, NH i,
and brightness temperatures, TB, is of high scientific value for a broad range of astrophysical …

ABSTRACT Context. Measurement of the Galactic neutral atomic hydrogen (H i) column
density, NH i, and brightness temperatures, TB, is of high scientific value for a broad range of …

The region around the Galactic Center (GC) is now well established to be brighter at
energies of a few GeV than what is expected from conventional models of diffuse gamma …

Abstract The Widefield ASKAP L-band Legacy All-sky Blind surveY (wallaby) is a next-
generation survey of neutral hydrogen (H i) in the Local Universe. It uses the widefield, high …

Planck has mapped the microwave sky in temperature over nine frequency bands between
30 and 857 GHz and in polarization over seven frequency bands between 30 and 353 GHz …

The excess of γ rays in the data measured by the Fermi Large Area Telescope from the
galactic center region is one of the most intriguing mysteries in astroparticle physics. This …

We present new measurements of cosmic infrared background (CIB) anisotropies using
Planck. Combining HFI data with IRAS, the angular auto-and cross-frequency power …

Context. The Effelsberg-Bonn H i Survey (EBHIS) is a new 21-cm survey performed with the
100-m telescope at Effelsberg. It covers the whole northern sky out to a redshift of z~ 0.07 …

We present new upper limits on the neutral hydrogen (H i) content within the stellar half-light
ellipses of 15 Galactic dwarf spheroidal galaxies (dSphs), derived from pointed observations …
