Laboratory Measurement of CH317OH Transitions in the Frequency Range from 216 to 264 GHz for Astronomical Application

The Astrophysical Journal
Methanol is one of the most abundant complex organic molecules in interstellar environments. Molecular lines of its rare isotopologues ^12 CH _3 ^17 OH and ^12 CH _3 ^18 OH therefore play a crucial role in examining the column density of ^12 CH _3 ^16 OH,

Mapping the interstellar medium in galaxies with Herschel [PDF]

, 2010
The standard method of mapping the interstellar medium in a galaxy, by observing the molecular gas in the CO 1-0 line and the atomic gas in the 21-cm line, is largely limited with current telescopes to galaxies in the nearby universe.

Spatially Resolved Star Formation Rate and Dust Attenuation of Nearby Galaxies from CALIFA, GALEX, and WISE Data

The Astrophysical Journal
We study star formation rate (SFR) indicators and dust attenuation of 74 nearby star-forming galaxies on kiloparsec scales, based on GALEX far-ultraviolet (FUV) and WISE mid-infrared (MIR) images with CALIFA optical integral field spectroscopic data.

Classifying spectra of emission-line regions with neural networks

Emission-line regions are key to understanding the properties and evolution of galaxies, as they trace the exchange of matter and energy between stars and the interstellar medium (ISM).

The Local Group L-band Survey: Probing Cold Atomic Gas in IC 10 with Neutral Hydrogen Absorption

The Astrophysical Journal
We present the first localized detections of the cold neutral medium (CNM) in IC 10, offering a rare view of dense atomic gas in a low-metallicity ( Z / Z _⊙  ∼ 0.27) dwarf galaxy.

Gamma ray lines from interstellar grains

, 1976
The existence of very narrow (FWHM or approximately = 5 KeV) gamma ray line emission from interstellar grains is pointed out. The prime candidate for detection is the line at 6.129 Mev from O-16, but other very narrow lines could also be detected at 0 ...

The nature and origin of disky elliptical galaxies [PDF]

, 2002
The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

Investigating the Interstellar Medium Conditions of Star Formation in High Redshift Galaxies by studying Dust Emission and Emission lines [PDF]

, 2015
This thesis presents the search for the \cii 158 $\mu$m emission line, one of the brightest far-infrared (FIR) emission lines, in a selection of $z>6$ (the Universe was less than 1 Gyr old) galaxies. These galaxies have been observed with CARMA and PdBI millimeter interferometers and no \cii nor continuum emission is detected.

JWST Observations of Cosmic-Ray-excited H2 in Barnard 68: Spatial Variations and Constraints on Cosmic-Ray Attenuation

The Astrophysical Journal
We present James Webb Space Telescope (JWST) NIRSpec observations of the starless dark cloud Barnard 68 (B68) that reveal the spatially resolved signature of cosmic-ray-excited molecular hydrogen (CRXH _2 ) emissions for the first time.
