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

JWST observations of polycyclic aromatic hydrocarbon (PAH) emission provide some of the
deepest and highest resolution views of the cold interstellar medium (ISM) in nearby …

Recent analyses of 21 cm neutral hydrogen (H i) emission have demonstrated that H i gas is
organized into linear filamentary structures that are preferentially aligned with the local …

The density structure of the interstellar medium determines where stars form and release
energy, momentum and heavy elements, driving galaxy evolution,,–. Density variations are …

We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive
galaxy group RO-1001 at z= 2.91 in the Cosmic Evolution Survey field. Keck Cosmic Web …

Context. The availability of large bandwidth receivers for millimeter radio telescopes allows
for the acquisition of position-position-frequency data cubes over a wide field of view and a …

Our understanding of the dynamics of the interstellar medium is informed by the study of the
detailed velocity structure of emission line observations. One approach to study the velocity …

We present the most sensitive and detailed view of the neutral hydrogen () emission
associated with the Small Magellanic Cloud (SMC), through the combination of data from the …

Abstract The North Celestial Pole Loop (NCPL) provides a unique laboratory for studying the
early-stage precursors of star formation. Uncovering its origin is key to understanding the …

Context. The amount of data collected by spectrometers from radio to ultraviolet (UV)
wavelengths opens a new era where the statistical and chemical information contained in …
