A Streamer Driving Misalignment in the Circumtriple Disk of GW Ori
The Astronomical JournalGW Ori is a triple stellar system with a disk featuring three misaligned dust rings. We present Atacama Large Millimeter/submillimeter Array molecular line data of CO isotopologues, revealing a streamer feeding the disk in ^12 CO and ^13 CO.

Contribution of neutral gas to Faraday tomographic data at low frequencies
Astronomy & AstrophysicsContext. The LOFAR observations of diffuse interstellar polarization at meter wavelengths reveal intricate polarized-intensity structures with an unexpected correlation with neutral H i filaments that cannot be reproduced in simulations with a low cold ...

The Astrophysical Journal, 1992 Spatial heterodyne spectroscopy (SHS) is a new instrumental technique for interference spectroscopy which promises to extend into the FUV (1200-2000 A) spectral region the large throughput advantage at high spectral resolution usually associated with Fabry-Perot and Michelson interferometers.

Diffuse Ionized Gas in the Anticenter of the Milky Way
The Astronomical JournalUsing data from the Large Area Multi-Object fiber Spectroscopic Telescope Medium-Resolution Spectroscopic Survey of Nebulae, we create a sample of 17,821 diffuse ionized gas spectra in the anticenter region of the Milky Way by excluding fibers in the ...

The Astrophysical JournalWe 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.

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.

Simulating the ISM and its Line Emission
, 2018 Integral field observations of galaxies now produce spatially resolved emission line diagnostic diagrams that can reveal the diverse processes impacting the ISM, and are necessarily dependent on the geometry and distribution of their gas clouds ...

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