, 2007
We review the current understanding of the emission line regions in radio galaxies at redshifts z 1. First, we consider the evolution of the emission line gas properties from the nearby Universe out to z 1.

Ground- and Space-based Dust Observations of VV 191 Overlapping Galaxy Pair

The Astronomical Journal
The Balmer decrement (H α /H β ) provides a constraint on attenuation, the cumulative effects of dust grains in the ISM. The ratio is a reliable spectroscopic tool for deriving the dust properties of galaxies that determine many different quantities such

Detection of an oxygen emission line from a high-redshift galaxy in the reionization epoch

, 2016
The physical properties and elemental abundances of the interstellar medium in galaxies during cosmic reionization are important for understanding the role of galaxies in this process.

Observations of DNC and DCO+ toward the ∫-shaped Filament and Starless Cores in the Orion Molecular Clouds

The Astrophysical Journal Supplement Series
Although the deuterium fraction is known to be a powerful evolutionary tracer, its variation within individual molecular cloud cores is still poorly understood.

Cold Water Emission Cannot Be Used to Infer Depletion of Bulk Elemental Oxygen [O/H] in Disks

The Astrophysical Journal
We reexamine the constraints provided by Herschel Space Observatory data regarding cold water emission from protoplanetary disks. Previous disk models that were used to interpret observed water emission concluded that oxygen (O/H) is depleted by at least

The MURALES survey

Astronomy & Astrophysics
We present the results of VLT/MUSE integral-field spectroscopy of the radio galaxy 3C 313 at z = 0.459, combined with HST and Chandra images. The high-resolution optical and X-ray images show the presence of two sources separated by 0.​​″63 (3.7 kpc ...

Stellar formation in HI interstellar bubbles around massive stars [PDF]

, 2006
Stellar winds from O and WR stars transfer large amounts of mechanical energy and momentum into the interstellar medium. They sweep up and compress the interstellar material, creating interstellar bubbles.

A New Framework for Interstellar Medium Emission Line Models: Connecting Multiscale Simulations across Cosmological Volumes

The Astrophysical Journal
The James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array have detected emission lines from the ionized interstellar medium (ISM) in some of the first galaxies at z ≳ 6.

Molecular cloud structure in the star-forming region W43

, 2013
In the struggle toward an understanding of the process of star formation it is one of the most important tasks to study the initial properties of the cold and dense interstellar medium. Stars are known to form in dense molecular clouds, but it is not yet
